Features of paving paving stones
This material is characterized by comparability of height with length and width. Such geometry allows you to ensure the high mechanical strength of each brick, which makes it possible to styling in places with increased patency. If the regulatory requirements were observed in the manufacture of paving stones, it will be:
wear -resistant;
Frost -resistant: a special production technology and a carefully selected composition allow the road surface to withstand at least 200 freezing / defrosting cycles;
environmentally friendly: even in hot summer with significant heating, the material does not emit harmful substances (unlike, for example, from asphalt);
Durable: individual manufacturers guarantee that the service life of the paving stones they offer will be at least 30 years;
aesthetically attractive: manufacturers offer paving paving stones of various shapes and colors, which allows you to form a different pattern in the laying process;
affordable: the cost depends on the characteristics of the raw materials used in the manufacture of products.
Statement technology
Laying begins with the marking of the site. For this, a detailed plan of the site is drawn up on a scale, there are places that will be bridge. These data are necessary to calculate the minimum number of paving stones. Another 10% for marriage and pruning are necessarily added to the calculated amount.
With the help of pegs and a nylon lace, the marking of the sidewalk paths on the ground is performed. In accordance with the marking, the soil is excavated to a depth, which will allow you to form a coating at ground level or slightly higher. The latter option is preferable, as it allows you to better remove melt water from the sidewalk.
Next, the base is prepared, the characteristics of which depend on the operational load. Most often this is a sandy base. To do this, put geopolrodically, pour a layer of crushed stone with a thickness of at least 15 cm, and then a layer of sand about 10 cm thick. To drain water, the surface should have a slight slope.
Next, the curbs are installed, the paving stones are laid from the edge to the center. The horizontal coating is necessarily controlled. Porridge are located as close to each other as possible, observing the selected drawing. After the laying with the help of a vibroter apparatus is completed, the pungent surface is compacted.
