Geosynthetics Corner – A Brief Summary on Geonets
Geonet is also geosynthetic material like the geogrid. Geonets are coated with the geotextile material on either side of the geonet and are called as drainage geocomposites. Geonets are made using the analogous manner as the geogrid, but the ribs are interconnected in a homogenous way through the extrusion process. This process continuously creates a net.

Geonets can be categorized in three ways as below.
1) Biplanar: These geonets are the common forms found and the intersection of the ribs have two sets. They are joined with desired spacing and angle according to the design style used.
2) Triplanar: These geonets have more stability because the gaps between the ribs are small.
3) Other types: These are the new types of geonets, where the extrusions are done in the box shape.

Applications of the geonet:
1) Geonets can be used in the construction of the roads as a surface course for both rehabilitation and new construction,
2) Patch works and pot holes fixing on the roads,
3) Reinforcement can be given to the joints in asphalt road,
4) Acts as a layer to drain off the water behind retaining walls,
5) Used as blanket for drainage beneath the surcharge fill, and
6) Used as blanket for drainage beneath the building foundation.
