Although of very similar configuration to geogrids, geonets are not installed for reinforcing purposes but rather for their in-plane drainage capabilities, which depends on the thickness of the ribs and their capillarity. They are frequently bonded with one or two layers of geofabric on each side (and are therefore often referred to as drainage geocomposites) or can be used sandwiched between two geomembranes. The geotextile/membrane stop the soil clogging the grid-like openings and reducing the drainage performance.

Geonets can be used in landfill applications within drainage layers, to drain away infiltrating water and leachate, and within the gas collection layer, to transmit gas to collection points. Geonets can also be used as wall, slope or roof drainage systems, under structures such as embankments and roads to drain away groundwater and contribute to stability of the structure and resistance to frost.
