GeoComposite

The geomembrane liner provides containment for landfill leachate. For leachate collection, Geocomposite provide high in-plane flow. The Geocomposite is composed of HDPE geogrid with Geotextile bonded to one or both sides to keep cover soil from clogging the geogrid. Geocomposite is placed directly on top of the primary liner.

Geocomposites can be manufactured as;

1^st Type: Geotextile + Geomembrane : one or both sides of a geomembrane

2^nd Type : Geomembrane + Geogrid : bonded Geomembrane and Geogrid

3^rd Type : Geotextile + Geogrid : on one or both sides of a Geogrid

Geotextile + geogrid Geocomposite are regularly used in intercepting and conveying leachate in landfill liner and cover systems and for conducting vapour or water beneath pond liners of various types. These drainage Geocomposite also make excellent drains to intercept water in a capillary zone where frost heave or salt migration is a problem. In all cases, the liquid enters through the Geotextile and then travels horizontally within the geogrid to a suitable exit.

In brief, Geocomposite that used in landfills and rehabilitation aims to supply base stabilisation and helps liquid and vapour flow.
