There was a time when the asphalt confidently entered the lives of not only urban but also rural residents, edging out second place cobbled streets and squares. Ribbons of roads, large parks and modest little park, paths and alleys were made of asphalt. Over the years, under stress and environmental factors are faded, cracked, eroded and after repairs took on the dark patches. People are accustomed to impersonal road differing from one another only in the number of holes, cracks and patches of fresh asphalt. Yet irresistibly attracted to you those rare places that still meets a bizarre mosaic of stone where you want to slow down and be absorbed, albeit briefly, in an atmosphere of past centuries in the history of the city, the amazing power of natural beauty. Feet to cross the small stone on stone, unique pattern of carefully selected old masters rocks attracts the eye, and it seems that even a merciless time stood still and gone before the joint creation of man and nature. Such bridge there, perhaps, in all the old cities. They remember the feet of thousands of horses hooves, the wheels of carriages and the Phaeton. On these roads passed the first cars, and now to him confidently modern life.
Appeared flagstones and eliminated the need to select stones of various sizes to create a road surface. Articles made of artificial materials have a definite shape and standard dimensions, so their installation does not take much time. In addition, Pavement strong and durable and beautiful. Different colors and the possibility of combining several shades allow you to create coatings with a completely unique pattern. And although the paving stone is still relevant, artificial tratuarnaya jets, simulating a variety of natural materials, is becoming increasingly popular. It is used almost everywhere: for paving the sidewalks, grounds in front of shops and cafes, gas stations, parks – for creating tracks and, of course, without it can not do in the regeneration of the territory of country cottages, guest houses and holiday homes. Cobbles pleases the eye, creates a special mood and gives the area a neat finished appearance.
Sidewalk tiles in two ways: vibropressing and vibrocasting. The first involves the use of harsh mixes with low water content, the second used plastic compositions, and embedded in vibroformy. Both methods allow to obtain excellent results, and the choice of method of production or that kind of tiles depends on the shape of the finished product, the solution composition and preferences of the manufacturer. To date vibrocasting became more widespread in the Russian factories for the production of paving slabs. With it, get the tiles of different sizes and shapes. Along with a smooth surface produced products that simulate brick, paving stones, boards, and even wood sawn. And the use in the production of color pigments to satisfy the most demanding consumers.
Of what is concrete used for the production of paving slabs? Like everyone else, it includes cement, aggregates, water and additives. But given the high demands for strength and durability of finished products, manufacturers use only the special materials. High-quality Portland cement M500 finished coating allows for a long time to withstand the daily load. As the filler used sand and gravel, and only certain factions and high compressive strength. To improve moisture resistance and resistance to temperature changes in the composition of the concrete mix is introduced plasticizers, air-entraining and hydrophobic additives, and the finest fibers of polypropylene, polyamide, or glass tiles make more endurance, longevity. Forming a three-dimensional lattice, synthetic fibers, thereby improving traction concrete components, and thus prevent the destruction of products made of it.
And, of course, since we’re talking about color tile in the production process can not do without color pigments. That they can get a simulation of various breeds of natural stone and even wood. By coating pigments for sidewalk special requirements: In addition to the stability of dyes in an alkaline environment of hardening concrete, they must withstand weathering and sunlight.
But the availability of quality components do not guarantee quality finished products. Only in strict compliance with the proportions and production technology can be obtained sidewalk coverage as all the requirements of regulatory documents.
Determine the quality of road paving tiles or without special instruments and equipment is almost impossible. However, if you know what it is worth paying attention to when choosing a product of this kind, can insulate itself from some errors.
First, remember that good tiles can not be cheap. One pigment for its production costs up to $ 10 per kilogram and per square meter of tiles used about 0.5 kg. Other components of the concrete mix, too, costs money, and modern equipment requires a certain cost. Too low prices suggest that the most likely products are made without compliance with technical requirements, and perhaps the materials were not of the best.
Smooth surface paving slabs not necessarily indicate its quality. If the gloss was obtained by the introduction of the concrete mixture of special additives, it can only rejoice. But practically the same external effect can be achieved by increasing the amount of water, and this impacts negatively on the strength of products. Check the quality of tiles or paving stones can be in mild shock products of each other: the ringing sound indicates that they were made by all the rules and meet the standard, a blank – indicates that the water is clearly overdone.
Special attention should be paid to the brightness of colors tratuarnoy tiles or paving stones. She can be reached either using expensive pigments, and this necessarily affects the price, or an overdose of conventional dye – in this case along with the price decreases and strength.
In addition there are external signs of specifications that products must meet. When buying a sidewalk coverage is necessary to ask the certificate and the results of laboratory tests. Any major manufacturer of such documents has and presents them on demand. With unknown companies offering tile for unreasonably low price case it is better not to have: most likely, the product looks decent and does not last for five years.
Paving tiles (pavers) has several advantages over the asphalt. First and foremost is the high environmental impact. In contrast to the asphalt coating of the tiles are not softened in the heat and do not emit volatile petroleum products. The gaps between the tiles prevent the accumulation of moisture and the formation of puddles, being a natural drainage systems. Artificial stone not prevent water and gas exchange of greenery, so parks, gardens and courtyards will entertain their visitors with fresh grass, flowering shrubs and trees healthy.
The second tangible benefits – durability. Stone, even if man-made, durable material and very durable. When the asphalt is covered with cracks from temperature changes and mechanical influences, Pavement does not lose its strength and attractiveness. But even if somewhere in the load on it is too high, correct the damage does not pose a big problem.
In contrast to the asphalt coating of tiles tratuarnoy parsed as easy as going. This allows you to effortlessly replace any of its elements, repair, which is under the ground water or cable, and then quickly restore the tile in place of its dismantling.
Elements of the covering of artificial stone can be compared only with similar products made from natural, but even before them, they have obvious advantages: lower prices, wide selection of colors, can deliver almost any amount of product desired shade.
Regardless of what kind of sidewalk coverage chosen to design parks, alleys, urban or suburban gardens, public transport or playgrounds, all of these places become strong defense and effective attractive appearance. By curly colored tile or imitating ancient cobbled pavements to walk much nicer than the faceless gray asphalt. High performance, environmental friendliness and beauty have made prefabricated pavement cover some of the most popular in urban areas and cottage communities. Neat paths and squares with a unique pattern confidently enter into our everyday lives, are hallmark prestigious areas and places of public resort. Along with the tile and pavers manufacturers offer borders, corner units, ramps for paving at differences of heights and even drains. And if laying paving slabs or pavers is done correctly, then the coating will last for many years without repair and replacement of its individual components.
