Product Description

Drainage Membrane with Bulges

Dimple HDPEgeomembrane 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 HDPEgeomembraneto provide the most valuable option.
