The three-dimensional composite drainage network is made of unique three-dimensional geonet bonded geotextile on both sides. The combination of geotextile (filter function) and geonet (drainage and protection function) provides complete "filter drainage protection" effect.The unique three-dimensional structure of three-dimensional composite drainage network core can bear high compression load and maintain a considerable thickness in the whole process of use, providing good hydraulic conductivity.

Application:

Three dimensional drainage net can be installed under the road base to prevent sand and gravel into geonet and provide effective drainage and reinforcement at the same time, it can also installed between the foundation and base to facilitate drainage. Drainage net is widely used in railway, tunnel, highway, municipal, dam, slope protection, garbage landfill, wall back garden, and field drainage reinforcement projects.

Features:

1.The drainage ability is strong, can withstand the long-term high load

2.The high tensile strength and shear strength of the pit

3.To reduce the probability of the geotextile is embedded in the network

core, can protect the long-term stability of the rate of water

4.The three-dimensional composite drainage net can withstand more

than 2000kpa compression load

5.Far greater than the ordinary drainage network resilience
