3D Geonet

3D composite drainage geonet is made of special geonet with double-sided bonded geotextile. The combination of geotextile (reverse filtration) and geonet (drainage and protection) provides a complete "reverse filtration-drainage-protection" effect. The special 3D structure of the mesh can withstand high compressive loads during the entire use process and can maintain a considerable thickness, providing good water permeability.
