Product Description

20mm Dimple Drain Sheet Roof Garden Retaining Wall HDPE Composite Drainage Board for Building and Construction
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.

Dimple HDPE geomembrane is made of high molecular, produced by extrusion and adsorption. The tri-dimensional space can drain gas and fluid. It is a multi-functional material, can form channels for water and gas easily, which is sound insulation and vibration isolation. In the field of civil construction can be widely used in building roof system layer overhead, planted roof drainage ventilation, basement waterproofing system protection, thermal and moisture isolation of the interior surface, road and rail tunnel drainage protection. In the urban land, space, material resources are becoming scarce today, Dimple HDPE geomembrane to provide the most valuable option.
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.
