Dimple Drainage Sheet drainage board

The Dimple drainage membrane is manufactured by HDPE resin. The extruding HDPE plastic sheet, then come into dimple shape. These dimples, in spatial structure with certain height,can resist long-term high pressure without deformation.

The second layer on the top of dimples heatbounded a filtration geotextile. This composite drainage membrane removes suspended soil particles and prevents clogging of the flow passages in the dimpled core.
Features
1) Excellent drainage function.
2) High tensile and shear strength
3) Anti-clogging
4) Multipurpose
5) High pressure resistance

Typical Applications:
1. Landfill drainage;
2. Roadbed and road drainage;
3. Railway drainage;
4. Tunnel drainage,
5. Underground structure drainage,
6. Retaining wall drainage;
7. Gardens,green roof and sports ground drainage
