Geocomposite Drain Plastic Dimpled Drainage Board For Water Percolation
Geocomposite Drain HDPE plastic dimpled drainage board sheet
Plastic Dimpled Drainage Board Description
Plastic Dimpled Drainage Board is a type of green roof systems which are drained by a special molding plastic sheets. Water is retained within dimple on the upper sides of the drainage plates; excess water spills over the edges of the plates and is carried off the roof.
The plastic storage and drainage plates 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.
