    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.
Advantage
Good flexibility and permeability
In coastal engineering, use its characteristics of good flexibility and permeability to buffer the impact energy of waves

Strong high pressure load
Can withstand a compression load of about 3000A for a long time

Good performance
Made with three-layer special structure, flexible and durable, strong acid and alkali resistance, not perishable, and long service life

Reduce cold expansion
Laying a three-dimensional composite drainage net can help reduce the impact of frost heave

Uniform mixing
It can hydrate the concrete evenly, whether it is for rigid roads or flexible road systems
