Geo-Net, also called drainage net Geonets are composite grid constructions used for drainage capabilities. Usually a geotextile is used as the drainage core with an upper and lower section of geomembrane. Geo-Nets are commonly used between two geomembrane liners as part of a leak detection system. They are also used above and below geomembranes to move liquids or to provide a path for gases.

Geo-Net is a high flow triplanar geonet. It utilizes a tri-planar structure with rigid vertical ribs. These ribs significantly increase the tensile strength and compressive resistance of the geonet.

Features :
  • Ability of the drainage structure to maintain high long term in-plane flow;
  • Ability of the drainage structure to withstand long term compressive loads;
  • Ability of the drainage structure to provide adequate shear stability.
