Plastic dimple waterproof drainage boards for roof garden
Dimple waterproof drainage boards Introduction:
dimple waterproof drainage boards is manufactured from High Density Polyethylene resins. Produced by extruding plastic sheet into dimple shape.These dimples,in spatial structure with certain height. Can resist long-term high pressure without deformation. On the top of the dimples, there is filtration geotextile to make sure the drainage channel ruing well without any block for any articles. For example,filling particles or concrete.
Dimple waterproof drainage board Property:
low-cost, high efficiency; durable; chemical resistance, resistance to puncture of plant roots; diverse application; simple installation and quality guaranteed.
Dimple waterproof drainage board Application:
1, Landscape engineering: garage top greening, roof garden, football field, golf course, beach project.
2, Municipal engineering: road base, subway, tunnel, landfill.
3, Construction engineering : upper or bottom layer of building foundation, basement wall, bedding filtration and heat insulation.
4, Traffic engineering: highway, railway basement, dam and slope.
