BPM drainage cell had been exported to over 36 countries. Our drainage cell is widely used such applications as roof gardens, podium landscaping, retaining walls, golf course, sports fields, bridge abutments, underground car parks, basements, under drains for slabs and foundations and subsurface drainage for permeable driveways, etc.How to Lay the Drainage Cell System
1. The waterproof HDPE geomembrane liner to be laid firstly. After the concrete protective layer or concrete slope finding layer is prepared, the dross and cement leveling at the laying site should be removed. The underground garage roof and roof garden require a slope of 2-5 ‰ to determine the construction foundation. Then it is ready to lay the drain cell.
2. Lay the 20mm drainage cell in the direction of the slope and lay them from low to high. The drained water is concentrated to the surrounding sewers or nearby urban sewers. Blind ditches and water collection wells need to be designed outside the roof of the garage to ensure smooth flow Rainwater is trapped on the roof of the garage, reducing the life of the underground garage!
3. The plastic drainage cell is laid. After laying a plastic grid (supporting mesh) above the drain cell, continue to tile the nonwoven geotextile. It is necessary to pay attention to laying the drain cell in any location to ensure that no dirt, large stones, cement, yellow sand and other dregs enter the front space of the drain cell. The laying of geotextiles must be overlapped by 5-10 cm to ensure the quality of the product. If it is found, remove it as soon as possible to ensure that the space of the plastic drainage cell is clear.
