Drainage Board with holes is made from high density polyethylene plastic and 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.

Feuatures:

(1)Waterproofing and drainage : from a channel,which water and gas can go through;
(2)Sound insulation and vibration isolation;
(3)Chemincal resistance,resist to plants' root;
(4)Easy to construction;
(5)Long life time.

1, Landscape engineering: garage top greening, roof garden, football field, golf course, beach project.
2, Municipal engineering: road base, subway, tunnel, landfill.
3, Construction engineering : upper or bottom layer of building foundation, basement wall, bedding filtration and heat insulation.
4, Traffic engineering: highway, railway basement, dam and slope.
