Green Roof Drainage Board Dimple Board Hdpe Dimple Board
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.
