Composite Drain Net
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.
Features
Geo-Net, also called drainage net, is a cost effective alternative to aggregate drains in containment systems. Geo-Nets take up less space than aggregate drains and can help to maximize volume in landfills and surface impoundments. Geo-Nets are commonly used between two geomembrane liners as part of a leak detection system. When placing Geo-Nets with geotextiles it is often effective to have the geotextile bonded to the Geo-Net in the factory. Geocomposites usually have a geotextile bonded to one, or to both sides of a Geo-Net. This creates a drainage structure that can be used between layers of geomembranes, and in many other unusual situations. The geotextile layers prevent the movement of soil fines into the Geo-Net drainage path that could lead to clogging and drainage failure.
