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. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case.
Geogrids are commonly made of polymer materials, such as polyester, polyethylene or polyproylene. They may be wovern 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.
Used in highway, railway, port, airport and municipal project. Support in the recovery working face of coal mine and roadway in the coal mine.
