Product Description

DESCRIPTION:
Dimple Drainage board is made of HDPE, it has high impact resistance and pressure resistance which can resist long-term high pressure. The drainage board can be produced at different heights, from 8mm to 60mm, to meet the drainage requirements of different projects.
The top surface of the dimple drainage board is bonded with a layer of geo textile to prevent soil particles from passing through, in order to avoid blocking the drainage channel and make the drainage channel smooth. Traditional drainage methods use masonry and gravel as the filter layer. The strength of Replacing gravel layer with dimple drainage board is that it can save time, labor and energy, save investment and reduce the load of buildings.


PRODUCT FEATURES:
Dimple drainage board can quickly and effectively export the rainwater, greatly reduce or even eliminate the static water pressure of waterproofing layer, through this principle of active water conduction can achieve the effect of active waterproofing.
