HDPE Plastic Dimple Drain Board
Drainage Board 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.
