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.
