Maybe someone will think what influence the price of geotextile?
Geotextile has excellent permeability, filterability, durability, acid and alkali resistance and corrosion resistant. Non woven geotextile can be widely used in railway, highway, sports hall, dams, hydraulic structure, tunnel, coastal mud flat, reclamation, environmental protection and other projects.
Generally, there are three colors of geotextile, white, black,gray and there are no difference from the function and the price are all same. However, recycle material or raw material, gram weight ,strength of the geomaterials effects the fabric price. Recycle material will effect the service life and may be the strength is not ideally as raw material geotextile, but the price is very charming.
At the top of underground garage, generally need to do waterproof and drainage engineering,on the flat floor need to lay drainage plate,then spread a layer of geotextile on the drainage plate. The function of geotextile is protection and filtering, can filter sediment into the drainage plate, and can protect the drainage plate, then covering the soil. The process of general roof greening construction is the same.
