Woven Geogrids (WFG & WG) are flat structures in the shape of a net. The geogrids are made from glass fiber or polyester woven together in a grid configuration, which may also be coated with a further protection layer, using synthetic material. They used for the reinforcement of asphalt roads.

Extruded Geogrids (EUG & EBG) are flat structures in a polymer (usual polypropylene) that are extruded and then pulled. This may be done in one direction (Uniaxial geogrids), or in the two main directions (Biaxial geogrids). They are used in soil and road paving reinforcement.

Composite Geogrid (CG) is a compound product made of geogrid and nonwoven geotextile, specially designed for soil stabilization and reinforcement applications. This product combined the advantage of geogrid strength with nonwoven geotextile excellent separation and filtration.
