Green Roof Drainage Board Plastic Drainage 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.

Description:

HDPE Plastic Dimple Drain Board

Dimple Drain board is made by 100% pure HDPE, the use of foundation or blow molding method to produce high density polyethylene (HDPE) geomembrane, pressed on geomembrane pressure after the special craft the closed swelled the frustum of a cone shape, having a three-dimensional space and some support stiffness, liquid, gas can flow excreted within its plate.
