Polymer sand paving slabs

Considering the relatively low weight of polymer-sand paving slabs, the costs of transporting large volumes of products are significantly reduced. The combination of all properties makes it possible to use it in places of mass attendance (both external and internal use). This the best option for covering areas of recreational areas (parks, cafes, etc.).

The tile production technology ensures complete repeatability of sizes, shapes and colors, so with the help of such tiles you can reproduce any geometric and color combinations. The result obtained is an order of magnitude superior to the use of conventional tiles, both in terms of appearance, and in terms of operational parameters.

Indeed, polymer-sand paving slabs are much more durable and resistant to the external environment than conventional ones. Especially if it is an urban environment, where there must be resistance to abrasion, high mechanical loads, exposure to oils and acid-containing liquids, hardness and strength, resistance to pinpoint splitting and many other reliability indicators.

The theoretical (calculated) durability of the polymer sand material exceeds 150 years, and in terms of color fastness, the tiles do not lose the color of the pattern forever. Its coloring with modern dyes that do not fade even in direct sunlight is carried out to the full depth of the material.

An important feature is the absence of dust emission from the surface of the coating (which is typical for other materials) and fumes during the hot season. Even under the scorching sun, the coating does not “gas” carcinogens, like asphalt. Polymer sand paving slabs are easy to wash, are designed for repeated use, and make it easy to repair, disassemble and re-lay individual sections of the coating.

Technologies do not stand still, but at the moment among paving coverings, polymer sand tiles are the most effective material in terms of durability and cost, which is universal in use due to its unique properties.

Polymer sand paving slabs are superior in their characteristics to conventional cement paving slabs. Polymer sand tiles are durable, frost-resistant, have a wide range of colors, can be of any shape and size, with a variety of patterns. The method for producing polymer sand tiles is simple and consists of several stages: preparation of mixture components, mixing of initial components, melting of the mixture, molding and pressing of products, hardening process, storage finished products.

Polymer sand tile production technology

To produce polymer sand tiles, three components are required: polymers (primary or secondary), sand of a uniform fine fraction without clay inclusions, and heat-resistant pigment. Polymers suitable for the production of tiles are HDPE (low-density polyethylene), LDPE (high-density polyethylene), and crushed film. The use of recycled polymers will help save on the purchase of raw materials and solve the problem of waste disposal. Secondary polymers are obtained by crushing and granulating industrial waste and polymer products (pipes, containers, packaging materials, films, etc.). At the first stage, the polymers are crushed or ready-made polymer crumbs.

The second stage of production of polymer sand tiles includes mixing the components in the proportion of 69% sand, 30% polymer and 1% pigment in a mixing plant. Pigments can be used both mineral and organic. The color of the future tile will depend on the choice of pigment. At the third stage of production, the thoroughly mixed dry mixture is placed in a melting unit (APN). The resulting homogeneous mass, ready for molding, is loaded into molds. During the solidification process, a homogeneous monolithic, high-strength solid structure is obtained. From the mold, the tiles are laid out on a flat surface, where they should lie until they cool completely and harden. The finished material is placed on pallets and sent for storage.

A good alternative to traditional concrete paving stones is polymer sand tiles. Thanks to its high performance characteristics, the product easily copes with the tasks assigned to it. Finished elements are distinguished by their low weight, high strength and wear resistance, and a large selection of colors and shapes. In this regard, many entrepreneurs decide to build their business on the production of this paving surface. The article will describe polymer sand tiles and their production. We will also describe the production polymer tiles at home.

Characteristics and advantages of polymer tiles

Polymer-sand paving products have the following composition:

• the main volume (3/4) is occupied by quartz sand;
• a quarter of the composition is high-pressure plastic;
• pigments.

Thanks to this composition, polymer raw materials are resistant to external influences and at the same time plastic, which facilitates the molding of the future product. The advantages of this material include the following:

1. These sidewalk tiles will last up to thirty years.
2. A special production technology allows us to produce a product that is resistant to temperature changes and its extreme values ​​(withstands up to minus 70°C). The plastic content of the tile increases the moisture resistance of the product. Thanks to sand components, the paving surface is resistant to aggressive liquids and oils. The tile can withstand significant loads.
3. During the manufacturing process, the product is given the desired color and shape, which guarantees a wide range of products. There is also a choice of surface options (matte, structured, glossy).
4. Recycling of PVC waste ( plastic bottles, boxes, bags) solves the problem of their disposal.
5. Light weight, strength and low abrasion.
6. When exposed to sunlight, the product does not emit toxic fumes.
7. Maintainability and easy installation.
8. The coating does not accumulate dirt and is easy to clean.
9. Possibility of making at home.
10. Wide scope of use (as covering sidewalks and platforms in private households and in public places).

Material used

The production of polymer tiles requires the following raw materials:

• used as a binder crushed polymers, they occupy a quarter of the volume (usually polystyrene, polypropylene and LDPE are used);
• Sand acts as the main filler (it accounts for 75% of the total volume), choose well-sifted sand of medium coarseness (it must be washed and heated to high temperatures;
• inorganic pigments(iron oxide is used to obtain red, orange or brown tiles; chromium oxide is used to obtain a green coating; titanium dioxide produces white tiles).

In order to reduce the cost of purchasing raw materials, they practice making tiles from plastic bottles and other PVC products, for example, boxes or even film (but in the latter case, no more than half the volume of all polymers). Since the polymer is neutral chemical composition, nitric acid acts as a solvent. To obtain a homogeneous mixture, the plastic is melted at a temperature of 180°C and high pressure. The melting process is called extrusion.

Necessary equipment

Making paving slabs from plastic bottles is impossible without the use of special equipment:

• plastic crushing machine;
• scales;
• melting apparatus;
• Press forms;
• press;
• extruder;
• When listing equipment for the production of polymer sand tiles, it is worth mentioning devices for cooling products;
• Forklifts will be needed to move finished products.

To produce plastic tiles at home, a molding press, a melting machine and an extruder are sufficient. If production is established in industrial scale, then you can’t do without a molding unit, a thermal screw mixing machine and a polymer crusher.

Important! When making tiles for your own needs, a drill with a mixing attachment is used to mix the components.

Also, to produce tiles from plastic bottles, you will need molds for pouring the mixture. They are bought on the Internet. There are molds made of plastic, rubber and fiberglass. Rubber molds the most durable (withstands up to 500 cycles), but also expensive. Fiberglass products are suitable for large tiles, but require additional lubrication. Most often, ABS plastic molds are used.

Advice! Don't forget to buy molds for making curbstones.

Technology for making tiles at home

The production of polymer-sand tiles is carried out in several ways:

1. Method of hot pressing of a polymer mixture.
2. Vibration casting using plasticizers.

Vibrocasting allows you to produce products with low porosity. The hot pressing method produces tiles with excellent technical and performance characteristics. In factory conditions, vibration casting and hot pressing technology are used simultaneously for the production of polymer sand coating.

Tiles for your own needs are produced directly on the street or in well-ventilated areas.

The manufacturing sequence is as follows:

1. Plastic bottles are placed in an extruder to grind the raw materials. Old plastic boxes are sometimes used instead of bottles.
2. The heated mixture is then poured into the melting apparatus. Moistened sand and dyes are also added there. As a result of mixing and simultaneous heating, a mixture of viscous consistency is obtained.
3. This composition is poured into molds and pressed using special equipment.
4. The finished products are cooled.

Covering technology

Laying polymer sand tiles with your own hands is quite simple. Laying is carried out on one of two types of base:

• crushed stone;
• sandy.

When laying on a sandy base, work is carried out in the following sequence:

1. In the place where the tiles are supposed to be laid, remove the soil to a height of 150-200 mm.
2. The soil is leveled and a surface slope is created for the drainage of sedimentary water. The surface is compacted.
3. On the sides of the path or platform there are ditches for laying curb stones. The bottom of the ditches is compacted.
4. Then sand is poured into the prepared ditches for the curb to a height of 50 mm. The sand is moistened with water and compacted.
5. Strictly along the line of the curb, pegs are driven into the ground and the cord is pulled.
6. The bottom of the grooves is filled with cement mortar and curbs are installed.
7. Geotextile strips are laid on the compacted base of the paths with an overlap of up to 20 cm. The edges of the strips are connected with tape.
8. Next, sand is poured in several layers, followed by wetting with water. Also do not forget about compacting each layer.
9. A reinforcing mesh with a cell size of 5 by 5 cm is laid on the sand. A dry mixture of sand and cement is backfilled on top of the mesh (keep a ratio of 3 to 1). The backfill is slightly moistened with water.
10. Now start laying the tiles. The elements are laid out on the sand at a distance of 3-5 millimeters from each other. A rubber hammer is used for leveling.
11. The seams between the paving elements are filled with sand.

Frequently asked questions about polymer sand products

How long have polymer sand tiles been on the Russian market?

For the first time this finishing material appeared in the early 2000s, when Russian production Imported technologies for the manufacture of composite products from a half-sand mixture (sand, polymer, pigment) began to be introduced. From now on, the products of this product group confidently lead in the implementation of various projects, providing serious competition to analogues made of concrete and metal. Our company has been working in this direction since 2007, which allows us to talk about serious experience in the production of polymer sand products. According to our data, finishing materials in this category are trusted by more and more users who have been able to evaluate in practice the many advantages of polymer road surfaces.

What is the scope of application of polymer sand paving slabs?

Polymer sand tiles can be laid on almost any area - sidewalks, garden paths, industrial premises, service stations, livestock complexes, including in private garages. However, the area of ​​use is not limited by climatic conditions. Prerequisite installation of polymer functional decor in areas with increased weight impact is the presence of a concrete base on which a sand cushion is installed.

How to pave a porch with polymer tiles?

When installing tiles on a porch, it is recommended to use a metal corner as a fixing stop. Otherwise, the process is similar to conventional installation on a cement-sand base, followed by filling the joints with a dry cement-sand mixture. The permissible size of seams is 6-8 mm.

How to lay tiles on a plinth and a used flat roof?

At installation work This type uses special support stands for piece elements. In order to lighten the weight of the structure, the tiles are laid on a layer of fine crushed stone, which is installed directly on the roof waterproofing.

Is it advisable to install polymer paving slabs in car washes?

In this case, there is a risk of the filling of the tile joints being washed out, which sooner or later will lead to surface deformation, so it is better to use tile adhesive. At the same time, tiles can be successfully used for paving car service centers and parking lots as a chemically passive material with high climatic resistance.

How to cut polymer tiles?

Using an ordinary grinder. Moreover, in this case there will be much less dust and waste than when sawing a concrete analogue.

How do polymer tiles react to major climatic factors?

Due to the extremely minimal porosity and low water absorption coefficient, the use of this road decor, unlike ordinary paving stones, does not deform under the influence of rain and cold weather.

Equipment for the production of polymer sand products

At the same time, polymer tiles perfectly withstand critical heat, practically without fading under the influence of active ultraviolet radiation.

What weight loads are polymer tiles designed for?

It all depends on the thickness of the piece of decor. Terrace tiles with a thickness of 22 mm are intended for paving pedestrian road surfaces and landscape areas for general purposes. Paving slabs with a thickness of 35 mm can easily withstand the weight of a truck.

What are the environmental characteristics of polymer sand tiles?

This finishing material is made from three main components - natural sand, polymer (stretch and LDPE) and coloring pigment. The last two components have the highest environmental safety, which is reflected in the relevant certificates. And the environmental purity of the prepared sand does not raise any questions.

Is it possible to reuse polymer paving slabs in other areas?

This high-quality road decoration is characterized by the absence of deformation even after prolonged use. Therefore, dismantling allows the tiles to be reused for paving to the appropriate specification. The created surfaces are highly maintainable, allowing you to quickly replace damaged piece elements without much labor.

What are the features of using polymer sand paving slabs in the winter?

Polymer tiles are distinguished by their anti-slip coating, which ensures good adhesion of the sole or wheel of a vehicle to the working surface. Snow and ice are easily cleared from the relevant areas. Moreover, even occasional strong blows from a crowbar are not capable of fatally damaging piece elements that have enviable impact strength. With any slight thaw, the tile, like a small heat accumulator, immediately absorbs the necessary portion of heat, which contributes to the rapid thawing of the ice crust without outside intervention.

How long does the color of tiles last when exposed to active sunlight?

If the manufacturer conscientiously follows the technology for the production of polymer sand products, namely - percentage components and their quality. For example, if during the production process you do not skimp on pigmenting dye, the tile will look attractive throughout its entire service life (up to 25 years). This priority is ensured by the principle of production technology, which forms a combination of pigment with other components at the molecular level. That is, the color of the finished tile is its natural physical and chemical state.

As for pricing, in this case you can directly buy polymer-sand paving slabs from the manufacturer without unnecessary trade markups.

How does extreme heat affect the strength of tile flooring?

With active, long-term exposure to sunlight, the tiles can expand within the tile joints, that is, in a linear manner. Similar changes are included in technical conditions operation. Thus, there can be no talk of any serious deformation, much less subsidence or “swelling” of the surface.

Can polymer tiles “swell” after installation during use?

Only in case of non-compliance with the installation technology - as a result of incorrect selection of components for the “cushion”, creation of too large or small seams, as a consequence of poor-quality compaction, etc. Subject to all technical advice(TR - 158-04) regarding the installation of sidewalks there should be no problems with the operation of polymer tiles!

Production of polymer sand tiles, paving slabs, hatches

Photo galleryDelivery Production Certificates

The raw materials used in the production of polymer sand tiles are polymer materials in various types: packaging, plastic containers, household products. More and more goods are packaged in polymers, and the range of building materials made from plastics is growing. Preparation of raw materials

The proposed technology for the production of polymer sand tiles from polymer waste involves cleaning and deep sorting of raw materials. It is proposed to adhere to a ratio of 40-50/60-50 of so-called soft (polyethylenes) and hard (polypropylenes, polystyrenes, ABS plastics, PET, etc.) polymers. In addition to polymers, sand is required in the production of tiles. It is used as a filler and must be dry, sifted without clay and dusty inclusions. It doesn't matter what color the sand is or what its origin is. The permissible sand fraction is up to 3 mm. Another filler that is more accessible in the selected area can be used, but before its industrial use, it is necessary to study its effect on product quality.

Pre-processing of raw materials

At the first stage, selected and sorted plastics are crushed in a crushing machine. It is desirable to have a 50/50 ratio of hard and soft polymers. For example: polyethylenes behave better at low temperatures and it is easier to obtain gloss on a product, but “hard” polymers will add rigidity and strength when heated in the sun. It is better and more convenient to work with granulate or polymer of the same brand. The result is a geometrically even and regular tile. The better the quality of polymer sand tiles, the more evenly the polymers and sand are mixed.

Preparation of polymer sand mass

After the first grinding, the plastic goes into an extrusion machine, where it is mixed under heat. Any chemist will say that it is impossible and unscientific to mix dissimilar polymers; It’s like mixing kerosene with water. But such a task is not posed - to mix polymers at the molecular level; it is enough to mix them using the viscosity properties of molten polymers. In the structure of polymer materials, films of polyethylene and polypropylene occupy a large place. They are added to the extrusion machine without grinding. The operator removes the resulting polymer-sand mass with the consistency of yeast dough with a mitt at the exit from the extrusion unit of the line, and, having formed a ball with his hands (agglomerate up to 100 mm), throws it into water for cooling. When taken out of the water, not completely cooled, but already hardened, the agglomerate dries quickly as it cools. The entire cooled agglomerate is re-crushed into chips with a fraction size of up to 1-10 mm. Thus, ready-made raw materials for the polymer-sand mixture are obtained.

Obtaining polymer sand mass and molding tiles

This stage of production of polymer-sand tiles is final. Some separate it from the procurement area and place it in a separate room. In addition to aesthetic considerations (preparing a polymer homogeneous mixture is accompanied by the release of gases and requires the provision of exhaust), there are also practical benefits: it is easier to carry out control and accounting. Mixing of sand, polymers and dyes occurs in a thermo-mixing unit (Melting-Heating Unit). It is important to maintain the mass of the mixture in the APN constant, adding new portions as the finished mass is consumed. The crushed polymer sand mass is mixed with sand and dyes in different proportions depending on the product being manufactured. For, for example, tiles this ratio is: 29/70/1, and for paving slabs it can be 24/75/1.
The ratio of sand and polymers also affects performance - the mass that contains more sand will take longer to heat up. This property should be taken into account when calculating costs and accounting for products.
It is important to obtain a high-quality mixture - the sand particles must be completely enveloped in polymers, without gaps. This is achieved by a unique shaft design designed by Polymer Technology in Orsk. More precisely, not calculated, but tortured by experimental designs and scientific research. As a result, the blades on the shaft are located so that when the shaft rotates, the speed at which the mass moves is different in 3 heating zones, which ensures complete melting of the polymer and high-quality mixing with the filler.
By the way, in this unit we see some design flaws, the change of which leads to an increase in the productivity of the entire line.
Thus, the resulting polymer sand mass with an outlet temperature of about 170-190 degrees and the consistency of tight dumpling dough is squeezed out of the machine after opening the damper. The operator cuts off the required amount with a knife, weighs it on scales, and having received the required amount (about 2 kg), puts it into the mold with a regular scoop.

Price list for polymer sand equipment

The mold, mounted on a press with a movable bottom plate, is cooled differently.
The upper part has a temperature of about 80 degrees, and the lower 45, or cooled as much as possible, for the fastest formation of the tiles (30-50 seconds).
This is done to create gloss on the outside of the polymer-sand tiles; the polymer is, as it were, squeezed upward, filling the pores between the filler. This is another secret of technology. Although such uneven cooling can lead to bending of the tiles, for this purpose they are placed on a cooling table and pressed with a weight until final shaping.
To obtain a matte surface of polymer-sand tiles, it is enough to cool the upper mold as much as the lower one. This is used for the production of polymer-sand paving stones. The dye may not be added, and the product turns out gray in color, like concrete.

NOT BUY FROM US IF YOU DON'T BELIEVE US!

Most manufacturers justify inflating prices for their polymer-sand products by the high cost of high-quality raw materials. But this is correct only when the manufacturer does not have the equipment and production space to prepare polymer raw materials on their own.

NOT BUY FROM US, IF YOU DON ' T BELIEVE US!

Time flies quickly and everything around changes. Now we all communicate using cell phones, although some 15 years ago this was an unaffordable luxury. You look out into the courtyard: instead of wooden swings on the playgrounds, almost all courtyards have brand new, “vandal-proof” children’s rides. Break them, don’t break them... They won’t break anyway. New technologies make it possible to improve the consumer quality of goods several times.

Who would have thought that there would be paving slabs that do not crack from impacts, do not absorb moisture and are not destroyed by time? Over the past decade, we have become accustomed to the fact that new technologies bring relief to our daily work, speed up work processes and decisions, and improve the quality of life in general. And we are ready to take a risk and try to lay out the platforms and paths of our beloved dacha with new tiles, but... only if they last long enough to justify the investment made. The only thing that holds us back are the questions that arise before using a time-untested new product: what if it darkens or fades in the summer? How will she survive the winter? Won't it split? And in general, the manufacturer writes only about positive qualities, but what if it is worse than classic cement? What if it will be harmful, will it emit any odors or gases when heated?

We will try to answer the questions that inevitably arise from the buyer.

It is safe to say that any product in this category manufactured conscientious manufacturer, differs high quality and will last a long time. And one more thing: equipment for the production of polymer sand tiles is expensive.

Review of machines for making polymer sand tiles

And there are no cheap analogues. In the garage, artisanal method You can’t make such tiles, unlike cement tiles. And it will not be possible to significantly reduce the cost of technology through the use of low-quality cheap materials. By the way, high-quality concrete tiles are made only large companies, and it is expensive, and everything else that is sold in the markets is cheaper and will last less. That is, in most cases, the quality of polymer sand tiles should obviously be higher.

As for odors, it is necessary to refer to the composition of the polymer-sand composite. Composition: quarry sand (75%), mixture of plastics (25%): high and low pressure polyethylene (approved for food storage and absolutely safe plastics with markings and international system), and heat-resistant dye. These components are heated at a temperature of 250 °C. These plastics are absolutely harmless and do not release carcinogenic substances into the atmosphere when heated. In addition, you need to understand that 75% of the product still consists of sand, and plastic is the binder.

In general, the presence of plastic as a binder (compared to cement, the binder in concrete tiles) gives advantages to polymer-sand tiles.

Let's look at all the properties in order:

+ Water repellent properties plastics give polymer sand tiles almost zero water absorption, and this extends the service life of polymer sand tiles to 20 years without destruction. Polymer sand tiles do not collapse during thaws and sudden temperature changes. Let's remember physics: water during a phase transition from liquid to solid state (ice) increases in volume, which leads to the fact that water, absorbed into the pores of the product and then freezing, increases in volume and literally tears apart the tile with high water absorption from the inside. That's why it happens that in the spring on freshly laid last fall concrete The paving stones and paving slabs already show signs of destruction. And the polymer sand tiles are intact and dry.

+ The water resistance of polymer sand products makes them attractive also because on the surface of the products no ice forms in winter– the tiles do not slip at all, and snow can be easily removed with a shovel.

+ Low water absorption explains increased frost resistance of the material(i.e. cycles of complete freezing and defrosting in a state of complete moisture saturation) - more than 500 cycles.

+ Plastic is lighter than concrete, so polymer-sand products 3-4 times lighter than concrete(this ensures easy loading/unloading and manual carrying along a track or path). This property allows our customers to independently organize the delivery and installation of garden paths, blind areas, porches and burial sites. This property of the polymer-sand material was quickly appreciated by electrical installation companies - a slab for covering cables made of a polymer-sand composite, within two to three years from the date of its invention, completely replaced the brick for protecting cable lines of 0.4-35 kV.

Anyone who has tried at least once “in use” products made from polymer-sand composite no longer refuses them - their use is very convenient and accessible.

+ The presence of polyethylene in the composition gives the products unique impact resistance– plastic is a more elastic and astringent material, which gives advantages during load tests. Polymer sand tiles 20 mm thick can withstand the load of pedestrian areas comparable to the load on concrete tiles or paving stones 40 mm thick! In addition, it belongs to “vandal-proof” materials - such material can only be split with considerable effort. Polymer sand tiles do not break during cargo transportation or when dropped.

+ The plastic embraces every grain of sand and paint in the mixture and, when melted, provides uniform coloring throughout the entire mass of the product. In addition, the coloring ability of plastic is higher than that of cement - such products are brighter, their color is more durable, the paint is not subject to fading. Provided that pigments with high hiding power are used, polymer sand materials do not lose color for a long time, continuing to delight with the brightness of the color even after several years.

+ Plastic, as we know, durable material, not destroyed by time. It transfers these properties to polymer sand products. The declared service life of the coating without destruction is 20 years.

+ The properties of plastic also give the material: acid resistance, alkali resistance, low abrasion, non-sparking. This is important for coatings with high traffic (entrance areas), as well as coatings: garages, industrial premises, livestock farms, etc.

± Plastic, as a binder, transfers paving slabs from the non-combustible (NG) section to the low-flammable (G1) and low-flammability(IN 1). The material does not burn or melt in fire (since it contains ¾ sand), but is charred. This means that when exposed to an open flame for a long time, the polymer sand material may begin to smolder, however, as soon as the fire source dries up, the smoldering will immediately stop.

+ Environmental friendliness of polymer sand composite undeniable - “food grade” plastic, construction sand and dye are absolutely inactive at elevated temperatures and in aggressive environments and are harmless to humans. These are not harmful plastics, polyvinyl chloride (PVC) and polystyrene (PS), which release toxic compounds when exposed to them. In polymer sand production it is simply impossible to work with such plastics - after all production is underway by high-temperature treatment, which is only possible for harmless plastics.

± Plastic imparts longitudinal thermal expansion to polymer sand products. At unstable temperatures (sharp warming) in the bright sun, a slight increase in geometric shapes in horizontal surface- up to 1-2 mm. The solution is to leave gaps between the plates - 3-5 mm. If you do not pay attention to this fact, it is possible that individual slabs will be pushed out of the covering - perhaps the tiles will rise like a “house” and you will have to re-lay the covering. This feature must be taken into account when laying, especially since not only polymer-sand tiles have such features - even concrete slabs on the highway rise “hill” from the heat.

The expansion of polymer sand tiles should not worry gardeners - after all, they do not have a question about strictly fixing their coating - to create paths, the tiles are laid on the ground with a sand cushion (prepared area) and compacted with a mallet. The sides of the path must be securely secured with curbs. If the thermal seams are observed, this coating will serve for many years without requiring refurbishment. If, when laying tiles, geotextiles are used as a substrate, then the issue of aggressive growth of weeds will be resolved - after a while, only small weeds with a superficial root system that can be easily removed from time to time may appear on such paths.

By the way, in winter the reverse process does not occur - the tiles do not shrink when cooling, but remain within their linear dimensions.

± The presence of plastic reduces the adhesion (adhesion of surfaces) of polymer sand tiles and cement mortar– the tiles will stick to the cement mortar due to the presence of internal grooves into which the mortar will fall. Laying on a layer of mortar bed (maximum thick sand-cement mortar) is allowed. However, tile adhesive, type EK-3000, with the joints filled with grout or sealant in the color of the coating, is much better at fixing polymer-sand tiles to the concrete coating.

+ And finally, plastic in products gives ease of processing(Used angle grinder, so-called “grinder”, cutting wheel for stone), saws smoothly, easily, without “fighting” and cement dust, as when cutting concrete tiles.
