Geo-Net and Geocomposite Drains

Geo-Nets are used to provide lateral transmission of fluid in many applications. Geo-Nets provide drainage layers in multiple lining systems.

    Features

    • High water flow under substantial loads
    • Equivalent to about 12" (300 mm) of sand drain
    • Ideal for drainage on slopes

    Applications

    • As drainage layer in a multi-liner system
    • Used as drain layers in landfills and ponds
    • For drainage in landfill cap applications
    • Good for gas vents under ponds
    • Drainage in dam cores

Product Description

 

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.
