Paving tiles

First, for the construction of roads used stone in its raw form, then they started to give him a cubic form, so there was sett. However, the current level of road construction to extract and process natural stone is very expensive, so it appeared a concrete paving stone - paving slabs. Today there are two common ways to cover the ground surface: paving roads pavement and asphalt. Curly paving tiles are laid on leveled gravel or gravel-sand cushion. For complex conditions provided for sand-cement mixture that contains from 100 to 150 kg. cement per 1 cubic meter. sand. Each layer of pillows, and then she laid tile thoroughly Compacting plate. Tile is laid with gaps of 2 mm-10 mm, which are filled with dry sand all coated and firmly. With this method of laying the water is not going on the tile surface, and goes into the ground. The presence at the base of the gravel does not allow water to rise upward, leaving the tile dry and thereby prolonging its service life. The advantages of paving slabs. Manufacturability Pavement - very tech material, laying it can be done manually or by using plitkoukladochnyh machines, and the presence shovoobrazovateley can do it as quickly as possible without pre-fitting with a guaranteed clearance. Convenience on the surface of paving slabs are no puddles. The presence of gaps allows moisture to evaporate freely penetrate through the tile flooring and eliminates the formation of a surface water mirrors. Environmentally Recent studies have shown that asphalt when heated above 25 degrees Celsius in the atmosphere starts to produce carcinogens. This means that on sunny summer days are in danger! Sidewalk tiles with natural climatic heating does not soften and retain their strength properties, it does not emit, unlike asphalt, volatile hazardous substances. Unlike asphalt does not violate the natural needs of green plants in gaseous and water exchange, which favorably affects the city appearance and health of citizens. Longevity of life pavement at least 25 years (since the frost pavement is 200-300 cycles). The porous structure allows water to go through the tile to the substrate, so the tile surface is not destroyed. Maintainability If necessary repairs (such as underground pipelines, etc.), paving tiles can be easily dismantled, to undertake the necessary work and lay it again. "Cobbles" is recommended to use in urban environments in places proleganiya underground utilities. Aesthetics Colours tiles can be varied, and color saturation with time is not lost. So summing up, cover with our proposed paving slabs have the following advantages: - high quality architectural and decorating - ease of use (ability to conduct road work at any time of year) - durability (frost resistance of paving blocks is 200-300 cycles) - in the summer does not soften and does not emit toxic substances - is excluded rising water tables.
