HDPE Dimple Drainge Board For Urban Landscaping Project
Product Description
The plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials. The plastic bottom plate is stamped into the convex points (or hollow cylindrical porous) of conical protrusions or stiffeners. After continuous innovation and research, the raw materials have been greatly improved and changed. Now it is pressed with polyvinyl chloride (PVC) as raw materials. The compressive strength and overall flatness have been greatly improved, with a width of 1 ~ 3M, The length is 4 ~ 10 meters or more.
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 Drainage board in place. A filtration geotextile covers the drainage core. The geotextile 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 Drainage board, hydrostatic pressure is virtually eliminated. Drainage board are very ligthweight, easy to handle and easy to install. They require no special equipment or skilled labor.
