Installation of the drainage system

At a distance of 1.5-2.5 meters from the surface of the foundation, a trench is born around the entire perimeter of the building, a sand pillow 5 cm thick is spread to a rammed bottom. Then a geotextile is laid, which will serve as a filter for silt. Geotextiles, dorn in Krasnodar and Sochi. A layer of crushed stone with a height of 10 cm is sprinkled on top of the geotextile, a drainage pipe with a slope of 5 mm per 1 m is laid, a layer of crushed stone is again poured and the free edge of the geotextile is wrapped with an overwhelming line, which will serve as reinforcing the drainage system. We fall asleep with the chosen soil. At the corners of the system, it is necessary to install wells with a diameter of 30 or 40 cm for the maintenance and cleaning of the system. They will also perform the functions of rotary wells. If there is such a necessity, then at the lowest height we set the collector through which the water will be displayed into the communal storm sewer system, or it will be absorbed into the soil through the arranged gravel polling. In order for the wells not to spoil the view, their lids can be covered with decorative elements or sprinkled with a small layer of earth, closing them with a film. To do this, you need to mark the places where the wells themselves are located.
