3D Composite Geonet

(Three-dimensional composite drainage geonet)

Product Inroduction:

3D composite drainage geonet is made of special geonet with double -side bonded geotextile.The combination of geotextile (reverse filtration) and geonet(drainage and protection) provides a cpmplete "reverse filtration-drainage-protection" effect.The special 3D structure of the mesh can with-stand high compressive loads during the entire use process,and can maintain a considerable thickness,provide good permeability.It can replace traditional sand and gravel layers,and is mainly used for drainage of landfills,roadbeds and inner walls of tunnels.

Product Feature:

1. Good drainage capacity(equivalent to one meter depth of gravel drainage).

2 high tensile strength.

3. Reduce the probability of geotextiles embedded in the network core and maintain

long-term stable drainage.

4. High pressure load for a long period of time (can withstand about 3000Ka compression load).

5 Corrosion resistance, acid and alkali resistance, long service life.

6.Convenient construction, shorten construction period and reduce cost.
