Tri-dimension Composites Geonet Used for Drainage
Product Description
Tri-dimension composite geonet is a chemically resistant composite comprised of a three-dimensional extruded polyethylene geonet core, thermally laminated to non-woven geotextiles on either one or both surfaces.
Typical applications
In landfill cover systems geocomposites are used to drain surface water away from the barrier layer decreasing percolation of water into the waste. geocomposites may also be used as a gas venting layer below the barrier layer to prevent the build-up of gases generated by degrading waste or underlying soils.
In landfill bottom liner systems geocomposites are used above the primary liner for leachate drainage and as a leak detection layer between the primary and secondary liners. Similarly, in liquid impoundments gecomposiye Drain may be used underneath the primary liner as the leak detection layer.
Product Features
- Cost-effective substitute for thick layers of coarse-grained soil in drainage applications, providing savings on materials, transportation installation and airspace.
- Preserves aggregate resources for structural applications where alternative materials can’t be used.
- Three functions in one unit: filtration, drainage and protection.
- Rapid installation in comparison to conventional soil drainage layers.
- Wide range of product combinations allows performance driven product selection at an economical price.
- Chemically resistant polyethylene geonet and polypropylene geotextile construction provides long life in harsh environments.
- Exhibits good interface shear strength with adjacent geomembranes and soil, allowing a high factor of safety against sliding
