Drainage Board

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.

· High Load Bearing 150t/m2 unconfined.

· 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.
