1. Composite  drainage board with non-woven geotextile is made of high molecular, produced by extrusion and adsorption. The tri-dimensional space can drain gas and fluid. It’s a multi-functional material, can from 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 production, 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. Plastic dimple drainage sheet to provide the most valuable option.

2. Composite Dimple HDPE drainage board with non-woven geotextile use the glue to make the drainage board and geotextile together.
