HONGXIANG composite drainage board is a dimple geomembrane,which produced by extruding plastic sheet into dimple shape.These dimples, in spatial structure with certain height ,can resist long-term high pressure without deformation.On the top of the dimples,there is filtration geotextile to make sure the drainage channel runing well without any block for any articles,for example,filling particles or concrete.

Typical application:

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.
