Product Details
HDPE drainage dimpled membrane for foundation dampproofing and wall waterproofing
Product introduction
Drain Board is made from HIPS or HDPE, and is formed as dimple shape. There are filtration geotextiles on the top of dimples to prevent silt passing through the drain board so that the drainage system will not be obstructed. Traditional drainage method is using the cobblestones or gravels as the filter layer to drain the water to the designated place. Using drain board to replace cobblestone filter layer is more economical and practical, also can reduce the load of the construction.
