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 and payments. Soils pull apart under tension. Compared to soil, geogrids are strong in tension.
Geogrid composites, apart from soil stabilization they will perform separation and filtration functions with the help of filter fabric laminate to it. Geogrid composites are utilized mostly when a high tensile strength material has to be installed between soils / aggregates with different particle sizes
