Geoflow Geocomposites

Geoflow is a high performance geocomposite for drainage and gas management applications.

Geoflow consists of a biaxial geonet manufactured from high density polyethylene heat bonded to a polypropylene nonwoven geotextile fabric available in either a single or double-sided configuration. The geonet provides a flow path for liquid and gases and the geotextile acts as a filter and separator, keeping soil and or waste particles out of the geonet drainage core.

Features & Benefits
