Best Quality Factory Price Geocomposite Waterproof Drainage Board
The dimple drainage board factory price is a kind of inexperienced roof systems that are drained by a special molding plastic sheet. Water is maintained among dimple on the higher sides of the evacuation plates; excess water spills over the sides of the plates and is carried off the roof.
The dimple drainage board made by China dimple drainage board suppliers are made of HDPE(high-density polyethylene), mistreatment high to inject plastic to make the hole-lump-shaped shell, with the stereo area and support level; within the high of the shell, covering with non-woven as filtering level for water percolation, water storage, and water evacuation.
