Tri-Dimension Composite Geonet for Drainage for Road Railway Highway Tunnel

Product Description

Geocomposite drainage Geonet 
Three dimensional composite drainage network is a new type of geosynthetics. Its structure is a three dimensional geonet core, and there are needle punched non woven geotextiles on both sides. The three dimensional geogrid core consists of a thick vertical rib and an inclined rib at the top and bottom, which can rapidly drain the around water from the road. 
It also has a pore maintenance system, which can block capillary water under high load. At the same time, it can also play the role of isolation and foundation reinforcement.


  • Product name: three dimensional composites drainage network.

Technical Parameter


The characteristics of 3D composite drainage net:
The drainage ability is strong, can withstand the long-term high load
The high tensile strength and shear strength of the pit
To reduce the probability of the geotextile is embedded in the network core, can protect the long-term stability of the rate of water
The three-dimensional composite drainage net can withstand more than 2000kpa compression load
Far greater than the ordinary drainage network resilience

1) Landfill drainage;
2) Roadbed and road drainage;
3) Railway drainage, tunnel drainage, underground structure drainage.
4) The retaining back wall drainage,
5) gardens and sports grounds drainage.
