Description

Introduction

HDPE Waterproof Dimpled drainage Sheet composite drainage board 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
