HDPE Plastic Dimple Drain Board
HDPE water drainage board also call plastic drainage sheet is a type of green roofing and foundation driange systems which are drained by a special molding plastic sheets. Water is retained and drained off within dimple on the upper sides of the drainage board; excess water spills over the edges of the plates and is carried off from the roof or foundations.
