Geonets and drainage geocomposites are used in a wide variety of applications within new cells and landfill closure systems
Rainwater collection layer:
Situated on the containment geomembrane in landfill closures, drainage geocomposites are used to prevent the generation of hydrostatic pressures in the soils of coverage
Leachate collection layer:
Geocomposites offer an effective drainage layer to prevent the accumulation of leachate on the containment geomembrane without reaching saturation
Leak detection layer:
Geonets and drainage geocomposites are arranged between containment geomembranes to generate a void space through which leak points of the main geomembrane can be detected and the leachate extracted to the outside.
Formed by a light triplanar HDPE geonet thermofixed to PP geotextiles on one or two bands
