When laying drains should be guided by the following considerations: – the distance between drains should not exceed 10-15 meters – cut off drains to streams of water from the site, located higher up the slope – the drain should protect the foundations of retaining walls, foundation tracks and platforms – drains should be laid with a slope as the water moves by gravity to him – to connect the drains better use of tees at 45 degrees. Joining Drain performed in the course of water movement. The drainage system of building foundations and structures for the device the system uses the same materials and the same principles as that for device drain collection system of surface waters. The only major difference, and – laying the drains running on the depth of the basement, but not less than 1.2 m (below the freezing ground). This depth is necessary, so that when winter thaws and spring snowmelt when the soil is not otmerzla, the system could work and take the resulting water off-site. System for collecting storm water problem of the system – the collection and removal off-site storm water collected from the roof gutters and pipes and drainage of water from paved areas. The volume of storm water is large enough. Not laying this system, you not only raskuete drown in the puddles after every rain, but also dampen the foundation and get swollen concrete foundation of your parking space. For a device collection systems rain water used PVC pipe with a diameter of 110 mm; dozhdepriemnye wells installed under the downpipes and gutters dozhdepriemnye, which are installed at the bottom of stairs (to collect water flowing down the stairs), and in paving, which occupies a large area (disperse water from paved areas), as well as a place where you plan to wash the car.
