Description
Introduction:
The drainage board is made from high density polyethylene plastic and it is a kind of geomembrane with dimples on the surface. Which have good properties such as high impact resistance and pressure resistance which can resist long-term high pressure, and avoid generate deformation. It could also be coated by non woven geotextile. The liquid and gas can go through freely between dimples.
Benefits:
- Waterproofing and drainage: form a channel, which water and gas can go through
- Sound insulation and vibration isolation
- Chemical resistance, resist to plants’ root
- Promotes fast and excellent plant growth
- Reduces urban flooding
- Reduces water contamination by filtering at source
- Strong structure can support heavy loads
- Easily installed
- Long service life
Applications:
- Landscape engineering: garage top greening, roof garden, football field, golf course, beach project.
- Municipal engineering: road base, subway, tunnel, landfill.
- Construction engineering : upper or bottom layer of building foundation, basement wall, bedding filtration and heat insulation.
- Traffic engineering: highway, railway basement, dam and slope.
