Plastic Water Storage Drainage Board Earthwork Products Water Drainage Hdpe Drain Board
Product Description
The plastic storage and drainage plates 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.

Manin features:
Water storage and drainage-Construction a drainage channel and water storage dimple with a certain three-dimensional spatial support.
Big load capacity- It is made of polymer materials, the anti-pression strength is more than 400kpa at most.
Heat insulation function- high-density polyethylene (HDPE) has good water resistance, heat insulation, high strength.
Water guiding function- the size of the gap between the protrusions of the drainage board determines the drainage capacity and the thickness of the air layer. Membrane and shell continuously form an independent space, liquid can flow inside.
Prevent puncture of plant roots- the HDPE is very strong can preven puncture of plant roots.
