- To work with rubber crumbs outdoors, the air temperature must be +20 ºC and without precipitation
Equipment for laying crumb rubber
Depending on the area that needs to be covered with crumb rubber, different equipment is used.
If we are talking about a large site, for example, a sports arena, exposed to, then you cannot do without an automatic crumb rubber stacker. It allows you to control the thickness and width of the coating, work at high speed (at least 800 square meters per day), and also distribute the material evenly over the surface, pressing it down so that it does not peel off.
(Pictured: auto stacker)
Usage: pour the prepared polymer mixture onto the surface in even parts, then level it using an auto-layer.
The budget and easiest-to-use equipment for laying rubber crumbs is a roller and a grater. A large roller and float are used to compact the coating, a forming roller is used for corners and joints. Before starting, the tools are soaked in turpentine so that the rubber crumbs do not stick to the surface.

Usage: pour the prepared polymer mixture onto the surface in even parts, then level it with a roller and press down with a grater.
The sprayer consists of air compressor and pumps. It is used for spraying a second layer of crumb rubber, to cover vertical surfaces with a layer of crumb up to 1 millimeter. It allows you to apply the components evenly and hide the unevenness of the first layer.

Usage: the polyurethane mixture is poured into the receiving hopper, from there it is fed to the spray gun using a pump and applied to the surface under pressure.
After laying the crumb rubber, you need to wait until it dries for 24 hours. Complete hardening of the coating occurs after five days.
Clean the equipment with organic solvents: acetone or xylene.
Description
The advantage of using special equipment is obvious. The equipment is easy to use and maintain; setting up the machine allows you to avoid wasteful use of components and produce a product of a given thickness and quality. Using the machine allows you to reduce the number of service personnel (on average, a team of specialists of up to 3-5 people is required: 2 on the machine and 1-3 auxiliary workers preparing the mixture). At the same time, labor productivity is several times higher than that of a non-mechanized team, at least 1000 m2/day. During participation production company in an open competition (tender), technical equipment plays an important role when the organizers determine the winner. Characteristics: 1. Filling width: 2500 mm 2. Movement speed: 0.8-6 m/min. 3. Filling capacity: 100-500 m/hour 4. Power: 8 kW 5. Weight: 850 kg. 6. Dimensions: (l*w*h) 3000*1800*720 mm. Description of the machine: 1. Working area: has a steel smooth surface with anti-corrosion coating, can work in harsh conditions. 2. Front scraper: Steel structure, the distance to the ground can be adjusted manually by screw, allowing you to set the coating thickness. The width can be adjusted using the upper limiter. 3. Control and working device: based on chain transmission. It has a speed controller, it can move forward, backward and along a curve. 4. Device for movement: if necessary, move the machine, on wheels. A hydraulic cylinder lifts the work surface from the tracks for manual movement. Pressure plate: has 4 functions: height setting, angle setting, temperature setting and vibration. The mixture is leveled by a plate after vibration, pressing and smoothing. Vibratory laying is necessary for proper compaction of the material, and heating up to 80 C ensures faster setting and hardening of the surface and improved coating quality. Areas of use and resulting products: The products of this equipment are seamless coatings made of crumb rubber, which are laid as a solid carpet on a hard or prepared surface. Basically, the coating is laid on playgrounds and sports grounds. The coating can be: . Colored; . Two-layer (thin colored top layer and thick black). In this case, the black layer is laid first, and after it dries, the colored layer is laid (with a layer or using a PTJ-120 sprayer). To make the colored layer, either black chips interspersed with EPDM or only colored granules from EPDM synthetic rubber are used; . Black. Crumb and glue sprayer PTJ-120 can be used as additional equipment. When spraying onto a seamless black layer, you can get 2 types of surface - water-permeable and waterproof, depending on the ratio of crumbs and glue, and the fraction of crumbs. When laying the top colored layer using a paver, you get a water-permeable surface with a drainage effect, on which puddles do not form even in rain. During the cold season, any type of surface described above can be filled with a skating rink, and in the warm season it will again be a sports or playground. Any color options are possible: any uniform color, coating with inclusions. On sports and playgrounds it is possible to apply various variations markings, drawing. Products can be from 4 to 20 mm thick (set during installation). general description technologies 1. Materials (crumbs, binder) and equipment (paver, mixer) are brought to the installation site. 2. Prepare the surface. If it is a concrete screed, dirt and dust are removed. 3. Primed with a thin layer of glue, which is used for cold installation. Glue consumption is from 100 to 300 g/m2 depending on the surface topography. This promotes improved adhesion of the material. 4. Equipment and materials are placed in place. 5. Mix the crumbs and binder (glue) using a mixer. To do this, the crumb and glue warehouse should be located next to the mixer. A scale is needed to accurately dose the binder material. Depending on the crumb fraction, type of mixer, air humidity and brand of binder, the ratio of glue to crumbs should be 15-20% by weight of the crumbs. After completing the cycle of mixing the components, the resulting mixture is moved onto a cart and transported to the laying site and poured onto the working surface of the paver. For mixing and transportation, 1-3 people are required, depending on the required productivity. 6. The scattered mass is leveled by the paver; the joints with the previously laid layer of material are leveled manually by the paver operator using special trowels. All possible surface irregularities are filled and leveled with material. 7. Drying time 8-24 hours (depending on temperature, humidity, brand of binder material). After this, you can lay or spray the top color layer. The second layer is laid without prior priming. 8. If necessary, markings or drawings are applied. The glue is mixed with the required color of dye, and the resulting mixture is applied with a brush to the pre-drawn markings. Another option is possible: the required pattern, logo, inscription is cut out of a roll of rubber material according to a template and laid with glue on the first black layer. Next, it is covered, sealed with a protective coating and a second colored layer of coating is applied on top. After drying, the protective material is removed, and we get a coating with a pattern, inscription or logo. -The surface on which the material is applied must be dry and clean. -Working at negative air temperatures and precipitation is not allowed. -The crumbs used must be dry. The size of the crumb fractions is from 1 to 4 mm. -Weight of 1 m2 of coating, 10 mm thick: 7-8 kg. -The service life of the coating is at least 10 years.
The Alfa-SPK company offers high-quality pavers for laying seamless coatings from crumb rubber.
The semi-automatic paver is designed for the production of seamless coatings based on crumb rubber and polyurethane glue of various thicknesses and purposes. Seamless rubber coatings are laid on a solid base: concrete or asphalt.
The main scope of application of the rubber paver is sports, playgrounds, playgrounds, sports arenas, running tracks and so on.
In the field of using crumb rubber, the direction of seamless coatings is considered one of the most profitable and most in demand. Laying high-quality rubber base on pedestrian roads, garden plots, children's playgrounds, at store entrances, in swimming pools, water parks, on staircases, in the subway, etc. It is becoming more and more part of our lives as a natural thing that we cannot do without in the modern world.
Automatic laying of rubber coatings using a paver has a number of advantages over manual application of seamless coatings:
- Significantly higher productivity than a non-mechanized team (at least 800 m² per day).
- Reduction of maintenance personnel (for laying coatings using a paver, depending on the volume of the site, 3-5 people are needed: 1-2 to manage the pavers and 1-3 auxiliary workers to prepare the mixture and transport it to the laying site.
- Laying seamless coatings of a given thickness and quality, reducing waste of materials.
- The ease of use and maintenance of the paver is obvious.
The pavement laid using a paver can be
- Black or colored. Numerous color combinations are possible. To make the colored layer, either black colored chips or colored EPDM synthetic rubber granules can be used;
- Single layer or double layer. In the case of laying a two-layer coating, a thick black layer is laid first, and a thin colored layer is laid on top after drying. The bottom layer - the substrate creates the necessary density, elasticity or softness, can be thicker or thinner, the top layer performs fastening and aesthetic functions. The top layer can be laid different ways: stacker, or using a Sprayer.
- Waterproof or waterproof. When laying the top colored layer using a paver, you get a permeable surface with a drainage effect, on which puddles do not form even in rain. A crumb sprayer can be used as additional equipment. When applying a top layer to a black seamless layer using a Sprayer, you can also obtain two types of surface - water-permeable and waterproof, depending on the ratio of crumbs and glue, and the fraction of crumbs.
- Thickness from 4 to 20 mm: this parameter is set during installation (the thickness of the coating depends on the safety of injuries in the event of a fall due to the shock-absorbing ability of the material).
- Width from 1500 to 2500 mm: this parameter depends on the paver model. The service life of the rubber coating is at least 10 years.

Work of the crumb rubber / rubber coating stacker
Automated laying of rubber coating has significant advantages over conventional manual installation. The use of a stacker makes it possible to reduce the number of maintenance personnel. Typically, on average, three to five specialists are needed. At the same time, labor productivity is noticeably higher than that of a team not equipped with equipment.
The crumb rubber stacker consists of several main elements.
- Firstly, the work area, which has a smooth steel surface with a coating that is not susceptible to corrosion, and therefore can function even in harsh conditions.
- Secondly, the front scraper, which is a steel structure with an adjustable distance to the ground to control the thickness of the coating. It is also possible to adjust its width thanks to the upper limiter.
- The third element is a control and working movement device based on a chain transmission. Equipped with a speed controller, it is also capable of moving forward/backward and along a curve.
- The next element is a device for movement. Designed to move the stacker. Runs on wheels. Hydraulics lift the work surface from the tracks for manual movement.
- Finally, the fifth part is the pressure plate. The most functional element. Performs four functions at once: setting height, setting angles and vibration, as well as temperature setting. The rubber coating, after vibration, pressing and smoothing, is leveled using a plate. Vibration processing is necessary for proper compaction of the material, and heating to a temperature of 800 degrees allows the surface to set and harden faster, which improves the quality of the final product.
Seamless rubber coverings that are laid as a solid carpet on a previously prepared hard surface. Based on the type of future site, its design and project, the paver allows you to create a wide variety of coatings.
They are:
- Black or colored. For the latter, pigment is added to the mixture of crumb rubber and polyurethane binder, or the coating is laid using pre-painted black crumbs or EPDM rubber crumbs.
- Single-layer or double-layer. When laying a two-layer coating, a thick black layer is laid first, and a thinner colored layer is laid on top. In this case, the bottom sets the required density, elasticity and other parameters, and the top is responsible for aesthetics and fastening.
- Waterproof and waterproof. The top layer can be made with a drainage effect, so that puddles will not appear on it.

In our country in Lately Rubber crumb coating is becoming increasingly popular. produced in sports facilities, children's playgrounds, both outdoors and indoors. This is primarily due to its shock-absorbing properties. Plus, the safety of rubber coatings, high anti-slip properties, elasticity, and resistance to abrasive wear. And the most important advantage of this coating is its seamlessness.
The final result, that is, the durability and quality of the coating, will subsequently depend on such a simple operation. If for some reason the granules are poorly coated with glue, and there is no connection between the rubber crumbs and the glue, this often leads to the appearance of holes, brittleness, cracks and bald spots in the coating. By the way, the lifespan of a poorly mixed coating is not long at all - a maximum of 2 years. And if all recommendations are followed, the coating will last more than 10 years. The quality of the coating is greatly influenced by the quality of the components included in the composition.
If in rubber crumb a large number of metal cord and textiles, this may affect appearance and the coating in this case will become very dangerous for use. The presence of dust will also worsen the adhesion of the granules to the glue and often causes the destruction of the coating. If the quality of the glue is very low and does not provide the required viscosity of the mixture, then the laid coating will become brittle, brittle and lack shock-absorbing properties.
Methods for laying crumb rubber
It is best to entrust the installation of the coating to professionals, so as not to change it several times a year in the future. Although the necessary components for such work are low cost. As you know, today there are four methods of laying crumb rubber coatings:
- sprayer;
- manual method;
- combined method;
- method using an automated stacker.
It is better to entrust the laying of crumb rubber to professionals, then the coating will be of high quality and durable
Types of equipment used
It is recommended to use special equipment for laying rubber coating. This allows you to reduce maintenance personnel and increase labor productivity. One of the specialized tools is the automated stacker rubber tiles. It is a steel structure on crawler and consists of a pressure plate and a front scraper, which is equipped with manual adjustment, which allows you to set the required coating thickness. The width can be adjusted using the upper limiter, and the plate has 4 functions.
