Product Introduction
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.
The plastic or HDPE drainage board are made from HDPE(high-density polyethylene), using high pressure to inject plastic to form hole-lump-shaped shell, with stereo space and support level; in the top of the shell, covering with non-woven as filtering level for water percolation, water storage and water drainage.
Product Feature
1. Convenient construction, easy maintenance and economy.
2. Strong resistance to load and durability.
3. The water can be partially stored and the remaining water can be drained quickly.
4. It provides sufficient moisture and oxygen for plant production.
5. Light weight, the roof heat insulation function strong.
