Three-Dimension Composite Geonets for Pavements Drainage

Product Description

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.

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
