Composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides. It has the property of geotextile(filtration function) and geonet(drainage and protection) Description
Composite geonet are composed of a high-density polyethylene (HDPE) geonet drainage core. The bi-planar geonet is made of two strands that over cross at sixty degrees whereas the tri-planar geonet is made of three strands, two that over cross at sixty degrees and one strand in between thus creating drainage channels that provide high flow capacity under high pressures and with very low ground slopes.
Composite geonet are composed of either bi-planar of tri-planar geonets combined with a layer of nonwoven geotextile either on one or two faces or with with a nonwoven geotextiles on one side and a waterproofing film on the other side.
USES & FUNCTIONS
Geonets and Drainage composites replace the traditional thick layers of gravel filters and drains therefore by reducing construction time and associated costs.
Bi-planar geonets provide high flow behavior in both cross machine and machine directions thus allowing liquid flow in all directions.
Tri-planar geonets provide high flow rates under high pressures in deep landfills and at very low side slopes.
The geonets and drainage composites are:
- resistant to chemical and biological agents that are typically present in soils and waste material areas
- Resistant against UV degradation through the addition of carbon black additives in the manufacturing process.
Application
- Landfill drainage;
- Roadbed and road drainage;
- Railway drainage, tunnel drainage, underground structure drainage.
- The retaining back wall drainage,
- Gardens and sports grounds drainage.
