House Green Roof System Garden Dimple Drainage Mat Plastic Drain
Board
Product Description
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.
