What is a geonet?

A geonet is a geosynthetic material consisting of integrally connected parallel sets of ribs overlying similar sets at various angles for in-plane drainage of liquids or gases.

Transnet® geonets are an extruded three dimensional bi-planar core made from virgin high density polyethylene (HDPE) for flow under high loading.

The geonet may have, heat laminated to this core, a nonwoven polypropylene geotextile for situations when the geonet has to provide a filtered drainage path. This product is called a Transnet® Geocomposite. Dependent upon the application the geotextile may be affixed to either one or two sides of the geonet core.


Transnets® Geonets may be used as either liquid or gas collectors. The typical applications for these products are in all applications that require drainage/collection of gas and leachates (mining and landfill) and filtration of sediments contained within these liquids. Transnet® is specially formulated to allow for use in high load applications such as landfill cells and where compression resistance is critical.
