Geocomposite is a whereby geotextile is bonded together with a Geonet to become a manufactured composite liner. For example, a Drainage Net encapsulated in a Non-Woven Geotextile.

The geotextile filters out finer particles (silt/clay) that would otherwise tend to clog the drainage net. May be used under a liner system in contact with the soil /CCL subgrade to handle Groundwater.
