Composite Drainage Geomembrane

Made from polymer resin, the composite drainage geomembrane is a waterproof and drainage material with three-dimensional space and certain support stiffness. Liquids and gases can go freely through it. It is characterized by being resistant to chemical corrosion, plant roots puncture and has the advantage of simple installation

This polymer geocomposite has both waterproof and drainage functions to fit in diversified applications. You can easily use it to build out the aerial layer to form drainage and exhaust passages, to achieve noise and vibration isolation function.

1. Sheet material: EVA, HDPE etc.
2. Dimple height: 8mm,12mm and 20mm.
3. Thickness: 0.8mm to 2.0mm.
4. Width: 2m to 3m.
