Green Sanjiang build drainage method of laying: 3, drainage board covered with geotextile, geotextile overlap each 10 ~ 20cm, to prevent mud and water through the geotextile clogging build drainage system, resulting in poor drainage, reduce storage capacity; 4, geotextile covered it 10 ~ 20mm coarse sand, forming a penetration filter layer can prevent the planting soil erosion; 5, covering the appropriate planting soil thickness. 6, to make drainage board product protection. After the pavement drainage board build drainage board manufacturers, wholesale, should not be allowed to direct the drainage board pushing trolleys, laying wood, bridleways transport material. To do with the shop with the filling. Build drainage board using high-density polyethylene (HDPE) or polypropylene (PP) shape formed by heat and pressure both to create a three-dimensional space has a drainage channel support stiffness, but also a light sheet water storage. This kind of plate itself on having water, drainage of two integrated functions, plates with high stiffness characteristics of space, compression is superior to similar products (by field test test), can withstand high compressive loads 400Kpa above, Meanwhile planted roof can withstand the extreme load conditions backfill process of mechanical rolling. Shandong Green Sanjiang build drainage board manufacturers | Construction build drainage board laying methods: 1. Waterproof layer and protective layer construction is completed, start paving drainage board. Drainage slope requires grassroots meet 2 ‰ ~ 5 ‰; 2.
