Drainage Board Foundation
Drainage board foundation is manufactured from High Density Polyethylene resins. Produced by extruding plastic sheet into dimple shape.These dimples,in spatial structure with certain height. Can resist long-term high pressure without deformation. On the top of the dimples, there is filtration geotextile to make sure the drainage channel ruing well without any block for any articles. For example,filling particles or concrete. The board is of low-cost, high efficiency; durable; chemical resistance, resistance to puncture of plant roots; diverse application; simple installation and quality guaranteed.
Drainage Board Foundation
The closed columnar and semi-conical shell boss of the SDM storage and drainage plate can form a continuous membrane and shell, with a three-dimensional space and a certain support rigidity, and liquid and gas can flow and discharge in it. It is a functional material with many potential functions. It is easy to construct an overhead layer during use to form drainage and exhaust channels to achieve the functions of sound insulation and vibration isolation.

Drainage Board Foundation
The Dimple Drainage sheet 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.
