A geogrid is geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls, as well as subbases or subsoils below roads or structures. Soils pull apart under tension.Compared to soil, geogrids are strong in tension.
Geogrids are commonly made of polymer materials, such as polyester, polyvinyl alcohol, polyethylene or polypropylene. They may be woven or knitted from yarns, heat-welded from strips of material, or produced by punching a regular pattern of holes in sheets of material, then stretched into a grid.
Currently there are three categories of geogrids. The first is punched and drawn geogrids, second is geogrids that are more flexible, textile-like geogrids using bundles of polyethylene-coated polyester fibres as the reinforcing component and third is geogrids that are made by laser or ultrasonically bonding together polyester or polypropylene rods or straps in a grid like pattern.
