HDPE Plastic Dimple Drain Board
The drain board is made of high density polyethylene (HDPE). The surface is equipped with a layer of grid and a layer of non-woven fabric to form a combined drainage board. It has the functions of drainage, waterproof, breathable, moisturizing and root blocking. It is suitable for large square greening and garage roof greening projects with deep soil layer and no water storage function. It can resist long-term high pressure without deformation. This long-term compression resistance can not only withstand the weight and load of the concrete floor, but also withstand the inevitable external pressure and impact during construction, such as the trampling of vehicles, workers and the impact of concrete pouring. Keep the bottom plate from deformation for a long time, so the original drainage can be maintained. The drainage board has only drainage function and is widely used in retaining wall, basement, tunnel, slope protection, platform and expressway subgrade.
