Product Introduction
Composite drainage net is made of special three-dimensional geonet bonded on geotextile. The combination of geotextile (filtration) and geonet (drainage and protection) provides a complete "filtration, drainage and protection" effect. The three-dimensional structure can bear high compression load during the whole use process, and can maintain a considerable thickness to provide hydraulic conductivity.
Product Features
1.Good permeability,Strong drainage ability
2.High tensile strength
3.Long term stable drainage permeability
4.Corrosion-resistant, acid and alkali, long service life.
5.Filter soil and gravel.
6.Easy to install and save cost
