Composite Drainage Net
Application
Landfill,railway system drainage,road or subgrade dewatering,tunnel and retaining wall structure drainage
Feature
1. Strong drainage (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3. Reduce the probability of geotextile inserting into mesh core, and maintain long-term water conductivity.
4. Corrosion resistance, acid and alkali, long service life.
5. Convenient construction, shorten the construction period and reduce costs.
Geotextile drainage matting, also called composite drainage net, is made of a unique tri-dimensional geonet heat bonded with a
nonwoven needle-punched geotextile, which is coated on one side or both sides. It has the property of geotextile (filtration
function) and geonet (drainage and protection) and provide a functional system filtration-drainage-protection.
Geonet drainage net core is extruded by high density polyethylene raw materials adding carbon black, ultraviolet and antioxidant
stabilizer. The unique tri-dimension structure of geonet drainage net can bear high compressed load in construction and remain the
certain thickness. The interlaced geonet forms into a drainage channel which has good vertical drainage properties.
