Geogrids are a type of geosynthetic product used primarily for reinforcement in the civil engineering industry. Some common geogrid functions and applications are: construction of retaining walls, steep slopes, roadway bases and foundations.
Made from polymeric materials like polyester, high-density polyethylene and polypropylene, geogrids possess properties that make it a good reinforcement solution for soil – especially strength and flexibility. They take the form of intersecting grids so that soil can push up through the gird and allow it to interlock with the polymeric material, creating a stable composite effect.
There are many types of geogrids, which are classified in two ways: manufacturing process and the direction of stretching.
Classification according to manufacturing process:
Classification based on the direction of stretching:
Uniaxial geogrids (high tensile strength in longitudinal direction)
Biaxial geogrids (high tensile strength in both directions)
Prices of geogrids depend on a variety of factors, such as the material used, production method, as well as type and function.
