Three-dimension Composite Drainage Network Introduction
Three-dimension composite drainage network is made of a unique three-dimension geonet bonded geotextile on both sides. It has properties of both geotextile (filtration function) and geonet (drainage and protection) and provides a whole function system “filtration-drainage-protection”.
The net core with its unique three-dimension structure can bear high compression load in construction and keep certain thickness, providing good hydraulic conductivity.
Specifications
Geonet thickness: 5-8mm; Width: 2-4m; Length as requested
Geotextile can be needle punched polyester geotextile, continuous filament PET nonwoven geotextile or Polypropylene nonwoven geotextile, and the unit weight normally 200g/m2.

Features
1. Excellent drainage function, able to bear long time high pressure load
2. High tensile and shear strength
3. Able to protect its long time and stable hydraulic conductivity
4. Able to bear more than 2000kpa compression load, its anti-pressure capacity much higher than common drainage network
5. Corrosion resistant, acid and alkali resistant.
Application
Landfill drainage; Roadbed and road drainage; railway drainage; tunnel drainage; underground structure drainage; the retaining back wall drainage; garden and sports ground drainage.
