Inquiry about 25mm Dimple Height Roof Garden Drainage Board for Other Earthwork Product
lastic drainage board have a flat back which is pressed against an underground structure such as a basement wall or subsurface footing. The pressure of backfilled soils holds the dimple drainage board in place. A filtration geotextile covers the drainage core. The HDPE Drainage board allows unrestricted flow of moisture into the core while it restricts the passing of soil particles which could contaminate and clog the core. Since most of the soil exposed surface of a subsurface structure is covered with the HDPE Drainage board, hydrostatic pressure is virtually eliminated. Drain board are very ligthweight, easy to handle and easy to install. waterproof board require no special equipment or skilled labor.
Height: 12mm, 15mm,20mm,25mm,30mm
