It is a kind of geomembrane with dimples on the surface. The dimples can be in cylinder and semi cone shape. It could also be coated by non woven geotextile. The liquid and gas can go through freely between dimples
Specification:
Sheet material could be EVA or PE etc., thickness from 0.7mm to 2.0mm, dimple height: 8mm,12mm and 20mm, width from 2m, composite layer is non woven geotextile, length could be made according to client’s request.
Property:
1. Waterproofing and drainage: form a channel, which water and gas can go through
2. Sound insulation and vibration isolation
3. Chemical resistance, resist to plants’ root
4. Easy for construction
5. Long lifetime
