All owners of private houses strive to improve their yard. They choose quality material for laying paths so that it will last for many years. The most suitable coating for paving a personal plot is polymer-sand paving slabs. This new building material features high quality and a variety of colors.
Material Composition
The composition of polymer sand paving slabs includes the following components:
- crushed polymers (polystyrene, polypropylene, high-density polyethylene), which are a binder and make up 25% of the total;
- sand;
- colorable pigments.
Tile production
In the manufacture of tiles, first of all, the constituent components are prepared, which must be of high quality. The most stringent requirements apply to sand. It should be sieved, washed, calcined and have a medium grain size. Then the components are thoroughly mixed by vibration. Next inThe extruder is loaded with the finished solution, heated to a temperature of over 250 ° C, and then formed and pressed under pressure in special forms. This technology makes it possible to obtain products of strict geometric shapes with a clearly defined pattern and the absence of voids in it.
Strength, density, uniformity, aesthetics - these are the qualities that distinguish polymer sand paving slabs. The equipment used for the production of this high-tech building material is modern automated lines that provide it with high performance.
Technical characteristics and physical and chemical properties
Polymer sand paving slabs, which are produced by vibrocompression, have excellent physical and chemical properties. The main ones are:
- compressive strength 50.2 MPa;
- density 2.05g/cm;
- % abrasion – 0.06;
- hardness (HRB) - 68-82;
- frost resistance - 300 cycles;
- % water absorption – 0.52.
Produced polymer-sand paving slabs with a thickness of 25, 35 and 40 mm. Its dimensions are 330x330 mm, in 1m2 - 9 pieces.
Benefits
Due to its manufacturing technology, polymer sand paving slabs are far superior in performance to cement-sand counterparts.
- Strength. Binders give the material plasticity. Unlike concrete tiles, it does not chip or crack,therefore, during storage, transportation and operation, its costs are minimal.
- Durability. This material is impact-resistant, resistant to temperature extremes, has a high abrasive resistance. The service life of the coating is more than 50 years.
- Sustainability. When heated, polymer sand paving slabs do not emit harmful substances, do not form concrete dust that is dangerous to others.
- Convenience. Tiles are laid with 3-5 mm gaps, thanks to which the water that enters the surface seeps into the ground without any obstacles, without forming puddles. The coating is easy to clean, does not absorb moisture and has the quality of anti-slip.
- Easy to install. Tiles are easy to process, which allows you to implement a variety of design ideas. It can be laid manually or with the help of specialized machines. Tile installation is quick and easy.
- Low cost. Polymer sand paving slabs (its price for 1 m2 is 450 rubles and more) meets all consumer requirements.
How to choose high-quality polymer paving slabs
When buying material, you should pay attention to the quality of coloring and color uniformity. It depends on the coloring pigment how long the aesthetic appeal of the coating will last. Extraneous inclusions, stains on the tile are the result of the use of low-quality dye or a violation of production technology. It's significantdegrades the quality of the material, reduces its strength and durability. The highest quality dyes are German-made.
Tile laying technology
Polymer-sand paving slabs are laid on a sand base, a concrete screed using a mortar or a cement-sand dry mix. Most often, the installation of the pavement under the tracks is carried out on a layer of sand, which requires compliance with the laying technology:
- In the place provided for laying the coating, the soil is removed by 15-25 cm.
- The surface is leveled to the slope and compacted.
- To install the curb, grooves are made, their bottom is compacted, covered with a 5 cm layer of sand. The sand is well watered and rammed.
- A cord is pulled onto the driven wooden pegs to mark the line of curbs.
- The bottom of the grooves is poured with cement and curbs are laid.
- Geotextile is laid on the surface for laying tiles, sanded, each layer is watered, leveled and compacted.
- With a gap of at least 3 cm, tiles are laid and the horizontal line is leveled with a rubber mallet.
- Sand is poured onto the surface of the laid tile to fill the joints.
Polymer-sand paving slabs can be laid using such a simple technology. The price of its masonry is from 420 rubles per 1 m2 material.
