Liquid tires for concrete waterproofing. Waterproofing materials for concrete. Materials for rolled waterproofing

Constantly wet walls, foundation, basement - how to protect yourself from this? We will tell you about relatively new on our market waterproofing mixtures, which they happen, consider the features of their use.

Previously, almost all works on waterproofing were performed using bitumen and bitumen-polymer rolled and tag materials. Over the past few years, new technologies came to our country. One of these new products became waterproofing mixtures, which are becoming increasingly popular with the device of the waterproof layer of concrete foundations, walls and basements.

There are several varieties of mixtures for waterproofing:

  • mixes for penetrating waterproofing
  • mixes for improving waterproofing
  • mixtures for plaster waterproofing
  • mixes for suture waterproofing
  • mixes for repairs of active leaks

The composition of dry mixtures for waterproofing includes cement, sand, chemical and polymer additives, which enhance the hydrophobic characteristics, frost resistance and the plasticity of the finished composition.

The leaders of the domestic market of waterproofing mixtures are Russian trademarks "Hydrothex", "Lakhta", "Calmatron", less frequently buy foreign Sika, BASF.

Waterproofing mixtures have a number of benefits:

  1. Applied on a wet or wet surface. There is no need to wait until the concrete is dry.
  2. Do not require special learning to perform work.
  3. Formulations can be applied both with external and on the inside of the building.
  4. The compositions eliminate microcracks during operation.
  5. The term of their service is equal to the service life of the entire concrete structure.
  6. Do not combustible, not toxic, environmentally friendly.
  7. Allowed for use in all sectors, including food.
  8. The waterproofing properties of the composition are preserved even with mechanical damage to the concrete structure.

Mixes for penetrating waterproofing

Waterproofing compounds of penetrating action are used in the device of the hydraulic protection of concrete and reinforced concrete structures. They cannot be used in combination with brick, foam and aerated concrete, since the pores of these materials are too large. In contrast to other waterproofing compositions, a mixture of penetrating action form a waterproof barrier is not on the surface of concrete, but in its thickness. The penetration depth of the composition can be up to 400 mm.

Concrete treated with this composition becomes more frost-resistant and durable, it increases sulphate resistance. In this case, air permeability does not suffer.

Mixes for penetrating waterproofing can be used in waterproofing foundations, basements, balconies, bathrooms, pools, water tanks and other chemicals, as well as underground storage facilities.

Works on the device of the waterproofing ball can be carried out from the inside and outside the premises. To apply the composition used ordinary tools and equipment for finishing work. The mixture is applied only on a moisturized surface. After the completion of the work, the processed concrete must be wetted every 6-8 hours for 3 days.

For a penetrating type waterproofing device, the following mixtures are used: "Lacht penetrating waterproofing" (cost 156 rub. / Kg), "Calmatron" (80 rubles / kg), "Hydrothes-y" (56 rubles / kg).

Compositions for coating waterproofing

The waterproofing mixtures of the coating type can be used when the hydraulic shore device is both concrete and brick surfaces. The thickness of the bathing of waterproofing is 2-6 mm.

There are two types of compositions: a dry mixture (one-component composition) and a polymer cement (two-component composition of a dry mixture and polymer water dispersion). The second option is used in the device of waterproofing surfaces of structures that are subject to increased formation of cracks, deformations, vibrations and sediment.

The composition is applied to a wet surface of 2-3 balls depending on the application method. Moreover, the second and third approach should be done, without waiting until the previous ball is dry, perpendicular to the penultimate.

The treated surface should be closed from direct sunlight to 24 hours. Finishing facing works can be carried out after 24-48 hours after the waterproofing device.

Important! Cannot be applied on top of the bulk sex and plaster plaster.

The most famous mixtures for coating waterproofing: "Lahta Refractory waterproofing" (cost 77 rubles / kg), IVSIL Vodostop (22 rubles / kg), "Alfapol go" (25 rubles / kg).

Plaster waterproofing

A simple way to simultaneously align the surface and arrange it with hydraulic protection. It can be used on the inner and outer surfaces of walls and foundations, on a dense concrete, on brickwork, on top of the already applied plaster. The mixtures provide increased waterproof, while maintaining vapor permeability.

It is applied to one or more layers with a conventional hand tool for finishing: a spatula, a spatula, cielma. To lay the next layer, it is not necessary to wait until the previous one dries, but there is a period of at least a period of at least between two arrivals. The thickness of the laying of the mixture in one occur - at least 2.5 mm. The composition is carefully smoothed in one direction.

In the process of work and after laying the surface should be protected from sun rays and drafts.

The most popular brands of mixtures for plaster waterproofing: Ceresit CR 65 (cost 35 rubles / kg), "Lachta plaster waterproofing" (54 rubles / kg), "Alith G-1" (38 rubles / kg).

Suture waterproofing

Mixtures for suture waterproofing are designed to seal joints and seams and their protection against the effects of aggressive media. First of all, they are used in pools, wells, balconies, foundations and walls.

The composition is applied to a wet surface. Before applying in embroidered gates, the solution should be applied and thoroughly close them. The applied mixture is necessary for 48 hours to protect against frost, drafts and sunlight. If there is a need, the surface is subjected to additional moisturizing and is protected by a polyethylene film. It is necessary to avoid drying.

Tile laying can be performed after 3-4 days after work.

For suture waterproofing, the following types of mixtures are used: IVSIL GIDROLINE (Cost 67 rubles / kg), "Lachta Suture Waterproofing" (99 rubles / kg), "Hydrothex-sh" (80 rubles / kg).

Comparative characteristics of waterproofing mixtures:

This table allows you to compare the main characteristics of the most popular waterproofing mixtures. With it, you can decide on their choice for the device waterproofs of your home.

Waterproofing mixtures are relatively new material on the domestic market, but the demand for them is constantly growing. This is due to the constant process of improving the material, improving the characteristics and production of new types of mixtures both in our country and abroad. Mixtures and compositions for waterproofing with proper selection and applying guarantee an excellent result.

Andrei Badovsky, RMNT.ru

The construction of various objects, especially buildings, requires an attentive attitude to the bearing elements. Requireors are fulfilled certain actions that contribute to increasing operational characteristics, including waterproofing concrete.

At the same time, it is important to choose the right waterproofing material and comply with the technological requirements for applying it, especially if you prefer to do everything with your own hands.

Is it possible to do without waterproofing?

For concrete, elevated porosity is characteristic. This negatively reflects on the performance of the material itself: it begins to quickly collapse under the influence of moisture surrounding inside. Therefore, he needs protection.

Action hydraulic protection

Waterproofing of concrete helps to increase its hydrophobicity. As a consequence, the climate inside the premises is significantly improved, the frost resistance of the concrete itself and the service life of the object constructed from it is increased.

That is why all surfaces should be protected, which in one way or another are exposed to moisture. Special attention should be paid to the foundation of the building.

Types of isolation

Depending on the direction of performance, waterproofing can be horizontal and vertical. The first is performed in the location of the foundation and walls, as well as at the floor level or below it for 15-20 cm. The vertical is most often running outside the building. At the same time, special materials for waterproofing concrete are used. We study them in more detail.

Bituminous or coating

Most affordable option, allowing to protect the treated surface at least 5 years. The mixture for waterproofing concrete surfaces consists of 70% of bitumen and 30% of spent oil.

To increase the service life, bitumen-polymer mastic can be used as a coating waterproofing, for example, "Slav" or Ceresit CR 65. Depending on the brand, such a mixture should be applied in a cold or hot condition.

Distinguishing accessibility, improving waterproofing has a low service life. It is poorly withstanding the external influence. After five years, and sometimes before, it may be necessary to re-perform waterproofing work.

Occake

Protection is carried out using rolled materials. It can be used independently and in conjunction with improving materials. Ruberoid received the greatest distribution. The material can be applied by burning and gluing.

In addition to the mains to the materials of this species include technolast, glassizol, hydrohoteloisol, tehnonikol, rubitex and others. Use with their manufacture as the basis of polyester made it possible to significantly improve the operational characteristics of the occasional material.
However, the calane waterproofing is characterized by small mechanical strength. When it is applied, it is necessary to carefully comply with technological requirements.

Liquid rubber

In contrast to the inlet waterproofing, liquid rubber is of greater durability, good clutch with the base. She is neo-coma. Allows you to get a smooth seamless surface. When performing work, one-component composition is most often used, for example, elastomix or elastopas.

When processing the surfaces of liquid rubber, it is worth considering the possibility of its destruction under the influence of direct sunlight. It should be necessary to provide for a special external protective layer. When choosing a sprayed liquid rubber, work on the waterproofing of concrete is better to entrust professionals.

Penetrating

Such materials are capable of penetrating the depth of concrete to a distance of up to 200 mm and crystallize there. The resulting crystals do not let the water, increase the frost resistance and prevent concrete corrosion.

"Hydrotect", Penetron and Aquatron-6 received widespread. They are often used if the foundation is required, the inner processing of basements, basement floors.
The use of penetrating compositions should be abandoned if the protected surface is made of a porous material or has a slit. In this case, the material is characterized by a high cost.

Plaster

Plaster waterproofing is a mixture consisting of a special plaster base and moisture-resistant components. As a rule, it is a hydrobeton, polymer concrete, asphalt mastic. Such waterproofing materials are produced under the trademarks "Hercules" and "Megavit".

It is worth considering that the formed protective layer can easily crack, for example, when shrinking the foundation. As a result, plaster waterproofing is distinguished by a low service life.

Screen waterproofing

Modern alternative to the clay castle. Protection is ensured using bentonite mats manufactured based on clay. It can be used separately and together with other methods. This method of waterproofing concrete is highlighted and can be used to protect non-residential premises.

Features of the installation of waterproofing materials

Sequence of execution mounting work Directly depends on the type of waterproofing material. It is important to comply with the manufacturer's requirements to ensure the necessary level of protection of concrete from water.

Separate species allow several possible options Fastening. What is preferred, depends on the operating conditions of a particular building. In order for the waterproofing of concrete and all work performed qualitatively, it is necessary to consider:

  • groundwater level;
  • inhomogeneity of the soil on a specific site;
  • feature of operation of a particular structure;
  • soil swelling force.

Applying bitumen

The prepared composition is heated to a liquid state. They produce the processing of pre-prepared surfaces using a roller or brush, thoroughly missing all sections.

The material is applied in several layers. The total thickness of such bitumen coolants should be about 3 - 5 cm. In the process of performing installation work, it is important to ensure continuous heating of the composition.

Installation of inlet waterproofing

In the case of burning before mounting the runner, it is necessary to process the protected surface with a special bitumen mastic or primer. Ruberoid canvas heated with gas burnerApplied to the vertical surface.

The layers are stacked with an overlap at 15 - 20 cm. When glueding, special adhesive masses applied to the protected surface are used.

Applying liquid rubber

For applying liquid rubber, roller, spatula or brush is used. The composition is applied on a dedicated and primed surface two hours after purification of the latter.

If elastopas is used, the protected surface must be treated twice. Before applying the next layer, you need to wait a day. On average, about 3.5 kg of material will be required to process one square. The remaining rubber can be sealed and leave for subsequent storage.

Elastomix is \u200b\u200bmore expensive, but it is applied in one layer. True, it is worth considering that this mixture is not subject to storage. Due to the addition of a special activator immediately before applying, the composition is vulcanized after two hours, further waterproofing of concrete is impossible to such material.

Application of penetrating waterproofing

The composition should be applied with brush or spatula on wet, pre-purified surface surface. Dry makeup mixed with water before use. Penetrating materials involve the application of several layers.

Application of plaster waterproofing

Plastering waterproof materials are applied in the same way as when the walls are plastered by lighthouses. Preferred is hot fashion. After a complete drying of the composition, the clay lock is necessarily performed and an inverse fill is made with clay.

Clay castle

Technology that allows you to protect, as a rule, the foundation from water. A trench is digging around the protected surfaces, on the bottom of which rolls crushed stone. The bottom and walls of the trench should be treated with clay. Before applying each subsequent layer, the previous one is dried. The existing space is covered with gravel or clay. Top is equipped with a scene.

Installation of screen waterproofing

The fastening of clay mats is carried out through special dowels. The laying is made with an overlap at 15 cm. Along the fixed mats, the clamping concrete wall is equipped, which will not allow mats to swell.

In waterproofing, almost all objects of industrial, residential, public appointment are needed, not to mention the responsible hydraulic structures. Such protection is able to extend the life building structures At least twice, ensures the long-term operation of the finish layers and coatings, the comfort of stay in the premises.

Water, without which it is impossible to ripen concrete, during operation begins to have a destructive effect on it. This is a fact caused by the capillary-porous structure of artificial stone.

Migrating on the capillaries, moisture moisturizes the enclosing structures, enhances the degradation of the material. In addition, the fluid often contains impurities alkali, salts, sulfates, which enhances the negative effect.

Finding into the pores, these substances can be repeatedly increased in the amount that provokes the destruction of carrier structures, peeling of paints and plasters, deformation of finish coatings. To avoid the entire mass of problems, effective waterproofing materials should be used.

In the design and structures, the groundwater penetrates below

Classification

The modern building market offers a mass of technological materials, helping to protect the artificial stone from the destructive action of moisture.

By chemical composition Internal waterproofing is subdivided as follows:

  • mineral - It is a dry mixture, the composition of which is represented by cement, modifiers, hydrophobizators. This solution is relevant where the concrete structure is not susceptible to cracking (internal plastered walls, monolithic floors). Before waterproofing, the base is aligned and moisturized;
  • polymer cement - This is a tricky combination of sand, cement, polymer additives, microfolocon. Such protection not only isolates, but also increases the strength of the grounds. By the way, it was the polymers that work on increased moisture resistance, cracking resistance;
  • polymer - The basis of protection is epoxy, polyurethane, acrylic resins. This solution guarantees one hundred percent waterproof, high elasticity, and active additives They work on good adhesion even with moisture concrete. Plus, polymers are capable of overlapping cracks at the base;
  • bituminous - materials of this group are made on the basis of oil refining products and amplified by synthetic or natural fillers. Application is implemented on a dry concrete, but such a layer is afraid of mechanical damage, so it requires protection with technical tissue, polystyrene plates, tie. Very economical solution, requested on horizontal surfaces;
  • bituminous polymer - This system of waterproofing is characterized by high elasticity, increased strength. Materials are divided into rolled (for roof), mastic (for underground structures), emulsions (for waterproofing mineral bases).

By type, the internal waterproofing of concrete is classified as follows:

  • occake - these are bitumen-polymeric rolls, membranes used for reliable protection of vertical and horizontal bases;
  • plaster - the product is used to protect waterproofing, creating high-strength coatings, processing docking seams;
  • painting and coating - solutions and mastic protecting concrete from capillary moisture. Good decision for internal processing and places where there are no vibrations and deformations;
  • lit. - Hot and cold waterproofing (asphalt, asphalt polymer) is represented as solutions and mastic. It is used to protect inclined, horizontal, vertical bases and temperature and shrinkage compounds;
  • penetrating - The compositions are deeply introduced into the structure of concrete, fill cracks, reliably preventing moisture penetration.

How nevertheless protect the concrete indoors? The most effective and practical processing methods are considered below.

Penetrating waterproofing of concrete indoors

The idea of \u200b\u200bpenetration (penetrating waterproofing) was born in Europe in the middle of the last century. The mechanism of work of cement materials is reduced to the free lime reaction (and it always has it in an artificial stone!), Capillary water and ingenious active reagents. As a result In the thickness of the bases, reliable protection is formed, blocking moisture penetration.

However, not everything is so rosy. Thanks to serious chemical reactions that make no sense to paint in detail, chemical equilibrium in the system can be impaired. Reducing the pH factor due to the binding of free lime can lead to early corrosion of reinforcement in railway structures.

The material must be high quality, with competently developed quantitative composition of active chemistry.

All this leads to the need for a painstaking selection of penetrating waterproofing. In practice, the effectiveness of this solution depends on the set "but", for example, the actual state of concrete, the nature of the surface, the overall dynamics of the structure. Other times more efficient to attract additives to concrete at the cooking stage.

Benefits:

  • fast standard of strength;
  • bulk waterproofing of concrete;
  • environmental safety is a perspective option for a device of economic and drinking water supply.

Disadvantages:

  • the size of capillary cracks should not exceed 0.3 mm;
  • concrete should not be subject to dynamic loads, is ordered.

Scope of application: interior walls Under the tile facing, floors and walls that act water, moisture.

Brands: Penetron, Wetonite, Lakhta, Kalmatron, Hydrothex.

Foolish waterproofing

This is a surface isolation. It can be said that thin-layer cocheutical systems on a cement basis give a very decent adhesion, becoming almost one with concrete (unlike the same rolled bitumen materials). Dry mixtures are optimal for waterproofing bases in static conditions, such as reservoirs, basements. Rigid waterproofing is indulging in water and forms a durable thin layer coating.

Polymer coating waterproofing after hardening retains elasticity, which works well in conditions of dynamic and temperature loads. This method is better to be implemented in underground garages, on foundations, in residential and industrial premises (both inside and outside). In any case, after processing, the surface can be finished with tiles or plaster, depending on the object assignment.

Benefits:

  • waterproof to the separation, which is effective in blunt rooms, basements;
  • vapor permeability;
  • crack resistance on the background of dynamic loads;
  • simplicity processing;
  • durability.

Disadvantages:

  • requires protection from mechanical wear.

Scope of application: Vertical, horizontal designs of residential and industrial premises, foundations, basements, garages.

Major brands of coating waterproofs: Bases, Liocol, Knauf

Horizontal shut-off waterproofing

This is the volume protection of concrete, by the way, one of the most efficient. The method is based on the injections of chemically active liquids in the thickness of the artificial stone. As a result after hardening, a waterproof barrier is formed. The basis of the system can be silicates, silicone compounds, and the last is an order of magnitude more efficiently, since the finest capillaries fill.

Benefits:

  • low viscosity well affects the spreadability;
  • resistance to aggressive media;
  • high grip with concrete;
  • excellent compression strength, bending.

Disadvantages:

  • high price;
  • waterproofing is arranged only at positive temperatures.

Scope of application:power closure of the cracks of concrete bases of any carrier structures.

Brands:Penetron, Baby, Insyl, Cerezit, Little

Specifications

Polyurethane waterproofing concrete

The most optimal option for high-quality waterproofing indoors becomes one-component polyurethane mastic. Such material after applying to concrete is polymerized and forms a solid seamless coating with moisture insulation properties. It is gratifying that polyurethane can be used as waterproofing under the laying of the tile, screed and as an independent finish coating.

Polyurethane isolation does not violate the vapor permeability of concrete

Benefits:

  • the polymer forms a durable elastic seamless layer;
  • excellent waterproofing properties;
  • application to any concrete, regardless of the configuration of the structure;
  • resistance to impact and abrasive loads;
  • after the work and polymerization, we can talk about the complete absence of toxicity;
  • resistance to chemistry and biological effects.

Disadvantages:

  • the material is applied under favorable conditions;
  • contains toxic xylene, which is not too nice when applied;
  • does not work for internal waterproofing tanks in contact with chlorine, say, in pools;
  • it does not work with a negative pressure of water, that is, it is not the best solution for waterproofing foundations.

Scope of application: Production and household premises with high humidity, technical zones Water treatment, insulation inter-storey overlaps In production, waterproofing under bulk polymer floors.

Brands:HyperDesmo.

Waterproofing of concrete joints

Practice is such that more than 70% of all concrete leaks occur through the seams. Therefore, the purchase of one waterproofing materials is clearly not enough - the protection of the structure from unexpected penetration of water should be complex. To solve these tasks, special waterproofing tapes have been developed.

Waterproofing tape is a high-strength, elastic material designed to strengthen the joints, moisture protection of seams and connections. Plus, self-adhesive ribbons can be conveniently sealing the corners, drain holes, commissioning of communications, compounds "Paul-Wall". As a rule, the material is used in a complex with cement solutions, polymer mastic, epoxy and polyurethane adhesives.

For laying waterproofing tape, no special tool is needed.

Benefits:

  • universality - Installation waterproofing tapes are available with the lower sticky layer, which ensures reliable and instantaneous fixation to any concrete structures;
  • durability - Modern ribbons are equipped with a solid metallized top layer. It works for high strength and protection;
  • waterproofing characteristics - the material successfully repels moisture, preventing its penetration into deep into the cracks and junctions;
  • easy use - The most convenient to lay the waterproofing tape in rolls. Special tool For this not required;
  • affordable price.

Disadvantages:

Scope of application:waterproofing of seams, joints, adjoins.

Brands: Penetron, Knauf.

Where to start treating concrete in wet and raw rooms

If the base is concrete, the beginning of the work should be based on clearing the seams, their fill with a solution, which will allow to align the surface. It will not be superfluous to attract special biocides that artificial stone from fungus, mold and in principle will not allow their occurrence. With the help of fluhatation, the salt should be transformed and deteriorated the base with metal brushes.

If the foundation asks for repair, fine-layer repair formulations should be used, eliminating the formation of cold seams.

The choice of the type of cleaning of the base depends on the degree of destruction of concrete, the nature of damage:

  • mechanical - with the help of perforators, pneumatic goods, crimes, sandblasting, grinding machines;
  • hydraulic - Here main role Plays water and devices high pressure (180-1200 atm);
  • chemical - concrete is cleaned with solutions of hydrogen, phosphoric acids;
  • thermal - Work oxygen or propane burners.

In addition, the waterproofing device will require a snap and tool:

  • for the preparation of work mixtures: Construction drill with a mixing nozzle (selected depending on the type of container used), in fact, it will also be necessary for both the net container;
  • to implement the waterproofing layer: sprayers, pumps, painting rollers, spatulas, brushes;
  • protective form.

Thin-layer repair formulations successfully operate when the device is quoted in the basements upon subsequent waterproofing

Technology of internal waterproofing by polyurethane compositions

The choice of insulation system depends on the tasks set. General recommendations are shown in the table.

Requirements for concrete

The surface must be dry, chemically neutral, durable, durable. It is unacceptable for the presence of peeling layers and rust. Traces of oils, chemicals, contaminants are removed using special chemicals.

The tensile limit is normalized - not lower than 20 MPa. If the reinforcement is not used during waterproofing, there should be no cracks above 0.5 mm on the concrete.. Large cracks and defects are expanding and repaired with sealants or repair makers.

Round roughness is normal - below 0.5 mm. If waterproofing with reinforcement is realized, the quality requirements are reduced. It is permissible to the presence of cracks and defects up to 3 mm, roughness - 1-2 mm. In any case, on the concrete there should be no protruding elements and angles.

Application technology

Before applying polyurethane waterproofing, filling of gaps around pipes, boxes, cables, inner angles is being implemented. Polyurethane sealant is taken to work.

The first operation is assigned to the priming.

When applying polyurethane waterproofing average consumption - 0.1-0.25 kg / sq. M.

Epoxy and universal primers are two-component. Before applying, they are mixed in accordance with the manufacturer's recommendation.

When 4-12 hours passed after the primary, the first layer of waterproofing was implemented. Polyurethane mastic and varnishes are mixed with the help of a construction drill and a mixing nozzle on low revs. Work is conducted manual way - With the help of brushes, maclavitz brushes or rollers (not foam) or mechanical - airless spray sprayers.

When applied, the material is evenly distributed over concrete, without non-crisis and influx. Visual control facilitates the use of non-ferrous mastic and varnishes. Recommended flow per 1 layer - 0.5-0.6 kg / sq. M. It is impossible to spend more than 1 kg per square, as this will lead to a worsening of waterproofing.

The second and the following layers are arranged with the interval of layer-by-layer drying (6-24 h). The finishing layer of polyurethane varnish or mastic is applied a day later. If the system uses quartz sand, it is pounced manually on the last layer of polyurethane mastic. When the material is polymerized, the quartz residues sweep the construction vacuum cleaner or brushes.

All specified exposure parameters are optimal to obtain high-quality inner waterproofing, but they are not considered absolutely rigid. If the application rules are followed, the term of complete polymerization is 7 days.

Speed \u200b\u200bsealing technology and seams

For internal waterproofing, two types of systems can be used:

  1. elastic waterproofing tape + single-component glue (average consumption - 400-600 ml / mp);
  2. elastic waterproofing tape + two-component epoxy glue.

The difference is that in the first case the glue retains elasticity, in the second - turns into a durable and solid material. Two-component glue is applied only on a dry surface.

Principle of work when preparing concrete:

  • low strength concrete fragments are removed mechanically (grinding, water jet, sandblasting method). For waterproofing, a durable structural concrete is required;
  • the irregularities that can prevent the tape flexible ribbon are restored by high-strength repair. The optimal choice It may be a repair mix of the M500 scraper from the brand Penetron;
  • if pressure lens are present on the design, they are eliminated using hydrophrom;
  • to ensure the high adhesion of one-component glue and concrete, the surface is designed as possible.

The choice of waterproofing tape should be based on the intended size of the deformation seam, its width. If there are no specific parameters, take the medium width + 200 mm. A glue is applied to the prepared concrete base. One-component - fully ready for work, two-component - mixed in proportion A: b - 2: 1 by volume. The mixer is working for about three minutes on low revs (up to 300).

If it is possible to apply material to wet bases, glue is applied with an effort so that water came out of concrete, air

A continuous smooth layer, 2-3 mm thick, with a width of each side of the crack - at least 80 mm should be formed. Work with a spatula. The glue is placed on the tape, making a small loop in the seam zone. The coating is tightly rolled with a plastic roller. From under the tape should be completely removed air. The correctness of actions says a small extrusion of glue along the edges of the ribbon (5-7 mm).

The outstanding composition is required to shame around the edges. Between themselves, ribbons glue 100 mm. For reliable waterproofing, welding with a construction hairdryer is used (nozzle 20-40 mm, 2300 W) at T 300-350 degrees. At the end of the tape, he is strongly pressed by any convenient method for 24 hours.

Enhancing technology of penetrating waterproofing

Work is carried out only in a stable, dry or matte wet concrete. All loose layers, paint, fats are removed. The base is necessarily moistened to complete saturation.

The cement mixture is indulging in water, in accordance with the manufacturer's recommendation. As a rule, 5-5.4 l of water is required by 20 kg of the mixture. Take a brush to work for plastering. The material is intensively applied to the surface with a flow rate of 1.5 kg / sq. M.

The second layer is implemented after binding the first (after 4-8 h). To avoid the occurrence of voltages should not exceed the regulatory consumption for one layer. For three days, the base is protected by a film from too fast drying, moisturized with water spraying, catering from mechanical loads.

Technology for applying bulk waterproofing

Works are carried out on dry or wet, purified bases. Epoxy injecting compounds Two-component and require mixing. Accurate dosage depends on the manufacturer. In any case, the hardener is mixed with the bulk of a low-robust drill.

After the kneading composition should be homogeneous, without visible rapids. To avoid poor-quality kneading, special attention is paid to the walls and the bottom of the tank. The mixing time should not exceed 2 minutes. Before the introduction of material in concrete, there should be cracks on the suitability for injection. For this, they are blocked with compressed air, all packers should be closed, except for one through which air is injected.

Application scheme:

  • according to the injection method, the material is injected under pressure. To do this, packers are driven into the drilled holes;
  • the distance between the holes depends on the slit parameters (depth and width). If the gaps pass concrete through, the holes are drilled from the inside and outside the premises;
  • packers are fixed in the excavations alternately on both sides of the crack;
  • if the cracks are very small, drilling is better to avoid, - in this case, the packer is fixed with the help of glue (injection pressure should not exceed 50 atm);
  • after fixing, the cracks are closed with surface insulation;
  • injections begin after 12 hours;
  • works can be performed using hand pump, two, one-component injection pump. By the way, in a two-component pump, the kneading composition occurs in the head of the mixer;
  • if deep vertical cracks are present on concrete, work starts from the lowest packer;
  • the material is introduced to the extent until it starts to flow from the nearest packer;
  • consistently fill all the plots;
  • when the material hardened, packers and surface isolation are removed.

Re-injection is carried out 15-30 minutes after the completion of the first

It is possible to implement the bay method. This is convenient when working on horizontal surfaces. Based on the bay holes, observing the distance of 50 cm from each other to the bottom of the crack. Next, you can start the mixture.

Safety technique

Works should be implemented in rubber gloves. Hands are pre-lubricated with protective cream. When waterproofing, it is often necessary to maintain work on the head. To avoid getting workers in the eyes, you need to wear helmets with eye protection or well-chosen protective glasses. Requires workwear, footwear.

All conditions for labor hygiene must be provided - at hand it should be sufficient number Water and soap for flushing pollution, disposable towels.

If synthetic resins hit the skin, the area is wiped with a pure tampon treated with protective cream. If the burn is serious, turn to the doctor. If the composition fell into the eye, flushing with running water 10-15 minutes. It is necessary to appeal to the doctor.

If the room is closed, you need to provide ventilation. In general, it is required to comply with the industry rules of TB. When using waterproofing, the requirements specified on the packaging signs.

Adhesives in an unlocked state can not be disposed of in the sewer, soil. It should be waited until the material hardens and can be disposed of as other construction costs.

Cost of internal waterproofing concrete

The cost of implementing the internal waterproofing of concrete depends on the selected methodology, the actual parameters of the concrete structure or structure, such as materials. The cost of preparing the grounds for work begins from 20 p / sq. M. Costs to the main spectrum of work - from 400 p / sq.m.

Approximate costs of waterproofing materials:

  • permeable compositions - from 230-300 p / kg;
  • polyurethane - from 512 p / kg;
  • bulk waterproofing - from 300 p / kg;
  • waterproofing tape - from 245 p.

conclusions

In practice, with the device internal waterproofing, random materials are often used, dry mixes from different companies and manufacturers with their properties and "know-how". The joint application of such compositions may cause the effect of rejection. A vivid example is a non-professional application in one protective "cake" of plaster and cement compositions without an intermediate primer layer. The spinning of the layers of penetrating waterproofing, which is caused by insufficient cleaning of concrete, etc.

When choosing waterproofing materials, it is advisable to use systems from one manufacturer (soil, primer, moisture protection, repair mixes, finish finishes And so on.)

The decision on the inner waterproofing is made individually. As a rule, plundered, basements, raw rooms need it in the absence of outer waterproofing, low efficiency and absence of natural drainage and drainage communications, shut-off isolation. The most effective is an integrated approach based on the use of mastic, cement mixtures, insulating tapes and bulk insulation. Polyurethane isolation is better left for walls, floors and overlaps.

Practical methods of waterproofing on the example of the floor of the basement are shown in the video:

Penetrating waterproofing for concrete is a mixture that is used to protect the foundations and other parts of the building from moisture. It is used both in private and in industrial construction. This mixture includes cement, sand, as well as various chemical components. The depth of penetration active substances Inside the concrete is 10-12 cm. This allows you to securely protect the foundation from the impact of moisture and extend its operational period.

Concrete blocks, which are part of the foundation, throughout the operation are exposed to moisture. Atmospheric precipitates contribute to the blurring of the construction of the construction, which can lead to serious consequences. Concrete has microcracks, through which moisture penetrates, falling into the basement.

It is also worth noting that water passes not only through microscopic cracks in the structure of concrete, but through the seams that are located between the individual elements of the structure. These places are vulnerable and also need reliable protection. Brickwork does not have independent resistance to moisture.

In order to ensure the protection of the foundation or any other design (for example, the garage floor made of cement) it is customary to use the waterproofing of the penetrating action for concrete. It is most often applied at the construction stage of the house. But in the case when the house is already built and there is a problem with moisture in the basement, then the waterproofing is applied from the inside.

Principle of operation protective composition simple and understandable. After applying for concrete, the process of absorption of chemical additives through microcracks begins. In case of contact with water, the mixture that filling the capillaries of the block is crystallized. Such crystals fill empty space and prevent the subsequent penetration of moisture. It is important to note that they do not dissolve in water.

Helpful information! In addition to waterproof qualities, such an impregnation strengthens concrete material, makes it more durable and wear-resistant.

To apply such a mixture, a wet surface is necessary, which distinguishes it from roll coatings and mastics based on bitumen. Before buying penetrating waterproofing for concrete, it should be clearly understood the principle of its action.

Penetrating mixtures protect the foundation not only on the effects of moisture, but also on the occurrence of mold and fungi. The process that is based on the interaction of free lime and moisture, allows you to reliably close the pores in the structure of concrete and secure the structure from destructive factors.

In which cases use waterproofing for concrete?

To speed up the process of penetration of waterproofing substances inside the concrete material, it is necessary to apply the composition on the wet surface. This method is very popular in cases where it is necessary to reconstruct the room. Often penetrating formulations use when there is no possibility to apply another protection method.

Penetrating substances are actively exploited to protect the foundations of private residential buildings. Industrial buildings also enter the list of objects that are processed by waterproofing of this type. The exposure to high humidity may be subject to objects:

  • cellar;
  • wells;
  • pools;
  • bathrooms.

This waterproofing material for concrete is not very popular, as some people simply do not know about its existence. However, the application of bitumen mastics is accompanied by certain difficulties, as they are very quickly frozen. In turn, the rolled materials do not guarantee one hundred percent protection of concrete from the destructive impact of moisture.

The main characteristics of penetrating waterproofing for the foundation

Waterproofing of any design can be carried out at the construction stage. Moreover, many experts recommend to apply this method. It takes into account the addition of dry substance to the cement solution. This mixture has an impact on the structure of the future foundation, the waterproofing properties of which manifest themselves from the very beginning.

Supplements to concrete for waterproofing contribute to the protection of the foundation from the effects of atmospheric precipitation and water in the ground at all points without exception. The operational term for this isolation will be equal to the expiration date of the foundation itself, as they are a single integer.

Note! Crystals that are formed in microscopic pores have resistance to water. They can collapse, passing water, but even in this case, with time, their restoration occurs. Regeneration of this type allows to ensure a high degree of protection of the foundation.

Advantages of penetrating waterproofing for foundation

An important advantage of such additives is their ability to speed up the construction process of the house. This is due to the fact that their use eliminates the need for a drying of concrete. Thus, time saving occurs due to penetrating waterproofing for concrete. Reviews of such compositions are predominantly positive.

When applied to a mixture on a concrete surface, it is necessary to know that it should be wet. Moreover, the higher this indicator, the faster the crystallization reaction is occurred inside the pores. The material itself after processing does not lose its properties, while maintaining all useful specifications, such as:

  • air permeability;
  • countertileness;
  • resistance to temperature fluctuations;
  • mobility.

The only indicator that is subjected to a change after applying waterproofing is waterproof. Such insulation is the most acceptable solution in the case when it is necessary to protect the foundation from moisture already the finished structure. This is due to the fact that it eliminates the need to excavate the foundation. You can buy waterproofing for concrete in a profile store or place an order via the Internet.

The penetrating composition ensures reliable waterproofing protection, regardless of which side it was applied to the foundation. Pressure groundwater In this case, there is also no impact on the quality of protection. Isolated surface, as well as all seams and butt points become immune not only to moisture, but also to an aggressive medium with different pH indicators.

Penetrating waterproofing for concrete: disadvantages

Any of the existing insulation has some drawbacks. The high characteristics of the penetrating compositions make them the most acceptable to protect the foundations and other structures, but they are not ideal. The main minus of such mixtures is that they are recommended to be used in a complex with other water refractors. For example, it is recommended to purchase a special substance intended for this to protect the sutures of the foundation from moisture.

Another disadvantage of penetrating aqueous isolation is that it is quite expensive. Depending on the brand and specialization of the mixture, the price of concrete waterproofing can vary from 50 to 350 rubles. For 1 kg.

Note! As a rule, insulation of this type is sold in bags, the weight of which is 25 kg.

Before starting work on applying such a composition to the surface, it is necessary to conduct preliminary training. It is very important to clean the wall so that there are no (even minimal) pollution left. Otherwise, the composition will not be well absorbed into the material. And also stands in advance to degrease the surface. Experts recommend using the garden hose to clean the wall, as water coming out under pressure is very well coping with this task.

The cost of waterproofing material can be very different depending on its variety and brand. The most economical and reliable option is the penetrating waterproofing of Lacht. You can buy such a mixture for a quite acceptable price (80-100 rubles per 1 kg).

All of the above manipulations are needed in order to provide free access to microscopic pores. In the presence of large slots and cracks in concrete Walls They are required to eliminate. It is recommended to smell such defects with a cement solution. This option is the most acceptable and simple.

It is also worth noting that the waterproofing mixtures of this type do not act if they use them to protect the brickwork surface. With their help, you can only protect and strengthen the seams in such a design. Thus, for brickwork, it is better to use more common and familiar protection options.

Nevertheless, taking into account all the minuses today there is no more effective means For waterproofing concrete structures. Before buying this composition, it is recommended to explore the companies that are engaged in its production. This will make it possible to choose the most reliable tool for a completely acceptable price.

Waterproofing of penetrating action: overview of popular brands

Currently, the construction market is replete various materialsdesigned to protect the foundation. Penetrating insulation for concrete is also no exception. It is implemented by different companies, each of which has its pros and cons. Experts do not recommend buying the cheapest compositions, since they are most often not distinguished by high quality.

The average price range is the most acceptable, as it includes quite good, high-quality brands of compositions. When choosing a necessary tool, consult with the seller. And also before buying penetrating waterproofing, it will be useful to learn about it on the Internet. To date, the following brands of penetrating mixtures are most common and effective:

  • Penetron;
  • Lachta;
  • Calmatron.

The first option is the most common. It is used about half a century worldwide. Lachta is distinguished by the variety of choice. A mixture of the squadron brand is considered the most universal penetrating waterproofing. Pools, wells, cellar and balconies - all these facilities can be protected by using the products of this manufacturer. There are many other brands that differ in their composition, use and action. However, the above companies have proven themselves in the production of products to protect concrete structures.

Penetron penetrating waterproofing: characteristics

The construction formulations of the brand Penetron are applied not only in private, but also for industrial purposes. These mixes appeared quite a long time, and the effectiveness of their use is tested by time. This mixture includes sand (quartz) and active chemical compounds.

The cost of such a penetrating composition is quite high - 250-300 rubles. For 1 kg. However, its technical characteristics fully justify such a price. Penetron penetrating waterproofing allows not only the foundation, but also walls, as well as floors made of concrete. Penetron consumption is quite easy to calculate, since it requires about 1 kg of composition to protect 1 m².

Note! Be vigilant, since domestic markets are filled with various kinds of fakes that can cost much cheaper than the original. The quality of such mixtures is in question, therefore it is not worth saving on the waterproofing of the foundation and other concrete structures.

Penetron penetrating waterproofing is used to protect against water wells, pools, floors and walls in bathrooms and garages. Before applying such a composition, it is advisable to get acquainted with the instructions and see the training video, in which all the nuances of the work will describe in detail.

Features of penetrating waterproofing of Lachta

The Lakhta brand is domestic, and its distinctive feature is in a wide range of dry mixes used for waterproofing concrete. Products of this brand are used for various tasks, including to enhance the waterproof of the seams.

The principle of action of such mixtures is the same as in the case of waterproofing material Penetron. The active chemical components penetrate the pores of the concrete structure and crystallized when interacting with water. Before proceeding with the application of Lacht waterproofing, it is necessary to prepare a concrete surface.

The cost of this mixture is lower than the previous composition, but the products have quite good feedback. The price for 1 kg of substance is approximately 120-180 rubles. According to the technical characteristics, such insulation is practically not inferior to the composition of Penetron. The price of penetrating waterproofing of Lacht causes its popularity and prevalence in the construction market.

This mixture is used to protect against moisture of concrete structures of industrial and domestic importance. With this waterproofing, it is possible to strengthen the water resistance of the walls and the floor in the cellar or garage. And it is actively used to protect pools, bathrooms and balconies.

Penetrating waterproofing Calmatron: price and properties

The composition of this brand is allowed to quickly and effectively eliminate small leaks that destroy the foundation of the building. This mixture helps to increase the strength of the concrete material. A feature of the waterproofing substance Calmatron is its versatility. The compositions of this type are used for insulation from the moisture of the following materials:

  • concrete;
  • reinforced concrete;
  • brick;
  • foam concrete;
  • aerated concrete.

The price of penetrating waterproofing for the concrete of this brand is the most attractive stamp of all the brands. The cost of 1 kg of product - about 80-100 rubles. Thus, for the bag whose volume is 25 kg, it will be necessary to pay approximately 2000-2500 rubles. Such formulations can be used both in the construction process and during the operation of concrete structures. Domestic consumers note quite quite good waterproofing properties of the squadron compositions.

Helpful information! Before purchasing this waterproofing material, it is necessary to consider one important moment. It is not recommended to be applied if the pH level on the object is located in the range from 3 to 11.

Liquid waterproofing for concrete: characteristics

In addition to dry mixtures, there are other ways to protect concrete structures from moisture destructive effects. One of them is the use of liquid waterproofing. Today you can meet a variety of liquid materials of this type, however, the most common are the following:

  • liquid rubber;

These materials have both advantages and disadvantages. Before purchasing one of them, it is recommended to explore the features of their use. With liquid means it is much easier to work, especially if you compare them with bitumen mastic, membrane films and rolled products.

Buy liquid waterproofing for concrete can be in the construction market, in the store or on the Internet. The cost of such compositions is above about 2 times, if you compare them with dry mixtures. Liquid substances providing waterproof of concrete are also convenient because they can be applied to an uneven surface.

Nuances of using liquid waterproofing for concrete

The process of applying the protective composition is quite simple. It does not imply heating the mixture, as in the case of bitumen mastic. It is also worth noting that the quality of waterproofing of this type is very high. Among other advantages, the liquid mixture can be allocated that it does not harm human health, since it does not allocate active chemical compounds.

Liquid aqueous insulation has resistance to high temperatures, so in the summer it is not necessary to fear that it will start melting. Such material is an excellent alternative to rolled and other insulators.

Liquid glass of concrete waterproofing is applied using the following tools: brushes, construction roller. The viscosity of the composition resembles the plow glue thickness. This mixture is applied with a thin layer, which after drying requires additional protection. This is due to the fact that the finished layer has weak resistance to mechanical effects.

Penetrating isolation of this type allows you to achieve excellent results. Impregnations based on dry mixtures increase waterproof, and liquid compounds Make a concrete structure almost invulnerable to water. But this method has some minuses. For example, make it with your own hands the layer of the required thickness is quite difficult. Therefore, it is better to use the services of a professional.

Characteristics of coating waterproofing for concrete

Many people confuse impregnation with coating insulation. There is nothing surprising in this, since they are very similar in their properties. Both of these varieties of waterproofing must be applied to the surface of the structure, after which they penetrate the microcracks in the entire microcrack. The difference of impregnation from the coating mixture is that it provides the protection of concrete from moisture, penetrating pretty deep into blocks. In turn, the coating mixture makes waterproof only the surface of the concrete.

Helpful information! Penetrating coating waterproofing is absorbed into the concrete material shallow, smoothly enough to ensure reliable and efficient adhesion with it. This is the main difference in impregnation from the coating.

A very important point is that the interlayer having such a small thickness should be applied correctly. Otherwise, it will not cope with its functions.

Requirements for modern coercive materials that ensure the impermeability of concrete for moisture, very high. It is important to note that in the case of applying a waterproofer from the side, which resists moisture movement, the claims to the material increase. This is due to the fact that it should resist the pressure of the fluid. This composition must have such characteristics:

  • good adhesion;
  • resistance to water;
  • elasticity.

The last characteristic is very important, since the concrete foundation is worn out over time and cracks appear in it. In such a situation, a good means of coating type should not be damaged.

Features of waterproofing paint for concrete

Waterproof concrete can be achieved with another means. It is waterproofing paint. It has many advantages. For example, it is very easy to apply to the surface independently, which causes its popularity among people.

Depending on the number of components that make up such paint, it may be one-component or two-component. Paint, which has a water-repellent effect, is most often one-component. This composition is enamel and is distinguished by high technical characteristics. If desired, it can be used as a suture penetrating waterproofing.

These compositions have a high degree of waterproofing, so they are most often used to protect the walls of pools and other tanks constantly in contact with water. Application of such paint is made by special pulverizers. Thus, it is possible to independently regulate the jet coming out of the tool.

Features of applying concrete waterproofing

Application of the waterproofing material for concrete is carried out strictly in accordance with the instructions. This process is conventionally divided into several stages. Experts are not recommended to retreat from them. Of course, it is much easier to use additives into a concrete for waterproofing, but not always the aqueous isolation is made at the construction stage of the building. Consider the algorithm of actions to which it is necessary to navigate when working with waterproofing compositions.

First of all, the surface should be prepared on which the penetrating material will be applied. The surface is carefully cleaned, after which it needs to be deguted. It will also be necessary to conduct a preventive check of waste communication. It should not have any damage.

Helpful information! If you want to hydroize the surface, which for many years already, then in this case it may be necessary to remove the old cladding. After that, the layer of plaster is applied. In some situations, it may be necessary to organize a new reinforcement.

Places that match the seams require special attention. They should be carefully laid. The same applies to wide cracks (more than 4 mm). The finished channels are closed using special sealing compositions. It is very important not to forget to close the slots at points corresponding to the passage of the pipes through the wall. For this purpose also apply sealants.

It is worth noting that to organize the penetrating waterproofing of the floor, the actions algorithm will be somewhat different. In this case, the work is simplified, since the need disappears in the stroke of the seams. But in general, both processes are similar to each other, as they mean careful surface preparation and application of the composition most convenient in accordance with the instructions.

In the next step, it will take to prepare a solution of penetrating aqueous isolation. At the same time, it is necessary to carefully examine the instructions in which all dosages and method of using the mixture are described. Further, the composition is applied to a pre-prepared surface. To do this, various tools are used, such as tassels, roller or special paintopult (depending on the properties of the waterproofing mixture).

Penetrating compositions are modern means that allow the foundation to be waterproof, thereby increasing its service life. Such mixtures can be very different from each other, but they all cope with their task better than traditional materials To protect concrete structures. When choosing penetrating waterproofing for the foundations of buildings, as well as other constructions from concrete, it is necessary to pay attention to its price, composition and method of applying.

In the process of operation and wear of concrete structures, cracks and other damage are formed in monolith. The situation is exacerbated by influence ambient and constant contact with moisture. To increase the service life of the construction and protect the concrete from the negative effect of precipitation and temperature drops, when installing concrete structures (or after the construction), the penetrating waterproofing is used, which protects cement surfaces much better than insulating mats and rolling backrest.

Before choosing a protective penetrating coating for concrete, it is necessary to consider the principle of operation, pros and cons of this agent.

Principle of operation of waterproofing impregnation

Penetrating waterproofing for concrete is a portland cement-based material, which includes special chemical additives (polymers, alkaline earth metals and salts). This solution to protect concrete from moisture was developed back in 1952 in Denmark, but he received widespread quite recently.

The principle of operation of penetrating waterproofing is as follows: the protective solution applied to the concrete surface penetrates the inside of the cement mass and moves along the capillar polishes filled with water. Due to this, the moisture reformable coating is formed not only on the surface of the monolith, but also inside it. At the same time, the mixture clogs all empties without disturbing the vapor permeability of concrete.

If liquid rubber is used for waterproofing, it will be impossible to achieve such an effect. The fact is that the degreasing materials, being applied to the concrete surface (inside which the moisture already contains) form a very dense and non-breathing film on it. Because of this, there is a so-called greenhouse effect - moisture inside the concrete is converted to a pair to which it is not necessary to exit. As a result, liquid rubber for waterproofing "provokes" the formation of mold on the walls and the ceiling of construction. The lack of waterproofing has the same disadvantage.

If you use the impregnation for the penetrating action concrete, then its components will join the reaction with the cement, due to which the crystals displacing pairs on the surface are formed. When moisture remains in the concrete mass, the growth of crystals stops.

Waterproofing of the penetrating action is able to fill the concrete thickness by 30-40 cm, while the moisture protection composition can be sealing cracks with a width of up to 4 mm.

The service life of the impregnation for concrete is up to 100 years (depending on the manufacturer and the composition of the means). In turn, coating or rubber mastic retains its properties not more than 30 years. In addition, the material has a mass of other advantages.

Advantages and disadvantages of penetrating waterproofing

If we talk about the advantages of the means of penetrating type to protect concrete from water, then it is worth highlighting the following advantages:

  • Waterproofing of deep penetration is suitable for almost all categories of structures (overhead and underground).
  • It is possible to apply the waterproofing material on a concrete surface even after years of operation of the structure (often such waterproofing is used in the restoration of buildings).
  • Since the material is anti-corrosion, then the reinforced concrete design will not be subject to rust formations. Protection of concrete from corrosion allows three times to increase the life of the construction.
  • Concrete does not need to be preheated before applying waterproofing.
  • Facilities for waterproofs are easily applied using a sprayer or manually.

  • Material is environmentally friendly both for people and for the environment.
  • After applying the composition, the walls do not require primer, so you can immediately apply paint for concrete and other finishing materials.
  • Waterproofing is used for temperature mode From -30 to +75 degrees, and some specialized mixtures withstand up to +105 degrees, so they are allowed to use for a hot concrete surface.
  • The waterproofing impregnation for concrete forms a strong film on the surface, which remains resistant to chemical and mechanical exposure throughout the entire operational period.

However, such protection of concrete from moisture has both definite disadvantages:

  • If it is known that the design will be subject to strong mechanical impacts that will lead to the formation of deep cracks, even when using specialized protective agents, the construction will be collapsed.
  • Not all penetrating fluids are suitable for brick surfaces, since there are no components that are missing for a reaction with bricks.
  • It is not suitable for porous concrete structures, as well as for buildings from a ceramzite concrete, Pojips, polystyrene foam concrete and other coarse blocks. Therefore, the protection of the moisture aerated concrete is rarely performed using penetrating compositions. For foam concrete, it is better to use rubber or other coating material.

To repair and protect concrete were produced efficiently, you must select best Material penetrating action.

What impregnation for waterproofing to choose

The greatest popularity today is a mixture of water and additive penetron. Such waterproofing works more active with high humidity of concrete. It also increases the frost resistance of the concrete building up to 400 cycles. It is worth such penetrating waterproofing of concrete from 300 rubles per kg.

  • Polynekrit. This composition is suitable for the processing of joints, seams and stages. The tool is distinguished by increased strength, good adhesion not only to concrete, but also to brick, natural stones and metal elements. Penekrit does not give a shrinkage and is often used together in Penetron. It costs about 250 rubles per kg.
  • Pedeplag. This tool also needs to add water. Peneplag applies if it is necessary to eliminate the fountaining lechy in concrete as soon as possible. In contrast to the analogs, this material is seized and dials the strength very quickly (for 30-90 seconds). There is also about 300 rubles.
  • Penebar. This is a good protection of concrete from destruction, especially if the monolithic cables and seams of cold type are located.

  • Ocked. Waterproofing OT. italian manufacturer Sold in the finished form and is used for both internal and external protection. Suitable for drainage systems and rooms with high humidity (bathroom, shower). Used used for concrete and brick grounds. The only drawback is to apply the wall before applying the material. Also, the mixture can withstand temperatures in the range from -35 to +85 degrees, but the composition should be applied at a temperature of more than +5 degrees. Osmiol is sold in packs of 25 kg, costs 3,500 rubles.
  • Hydrotect. This "waterproofer" includes cement, sand and special penetrating additives in concrete. Thanks to special fillers, this composition can be used even for those buildings that will be subjected to a strong shrinkage and vibration. Hydrotect can be two types: hydrotex B is used for internal waterproofing, and hydrotex y - for external. Manufacturers argue that this composition is capable of penetrating into the concrete mass per 1 m.

Useful! If the construction is exposed to shrinkage or vibrations, it is also recommended to pay attention to the compositions in which Latex is present.

How to apply penetrating waterproofing

For applying deep penetration waterproofing material, do the following:

  1. Prepare the surface. To do this, it must be cleaned from drowshes, dirt and dust. If you work with polished concrete, it must be treated with a sandblast solution of hydrochloric acid (Proportion 1:10). This is necessary in order for the pores to be opened. If there is a mold on the surface, then it must be treated with an antiseptic agent.
  2. Do at the base of the shots in the fields of joints and increase the crack to 2.5 cm deep and up to 2 cm wide. This will improve adhesion.
  3. If you treat a brick wall, then over all the masonry you need to drill the sheets with a depth of 3 cm. The distance between the spurs (drilled at an angle of 45 degrees) should be about 5 cm. After that, the recess is washed with water under pressure and filled with plaster.
  4. Moisten the surface with water using a roller or sprayer.
  5. Divide the solution as indicated in the instructions. It is better not to cook at once the whole mixture.

  1. Apply waterproofing on the wall, ceiling or floor with a conventional brush or roller. At the joints the most convenient to work with a spatula.

The compositions are usually applied in 2 layers with a thickness of 1 cm, with a break of 1-1.5 hours. The material does not need to rub or smear.

Knowing how to protect the concrete surface from moisture, you not only increase the service life of the construction, but also increase its frost resistance.
