HQ1: Typical Geogrid
What is Geogrid?
A geogrid is a geosynthetic made from a polymeric material. Geogrids are formed by weaving or knitting intersecting ribs with appropriate apertures (open spaces for the ribs to fit into). Primarily, a geogrid is used for reinforcement applications in various types of construction projects but can be used for separation applications as well. They are open grids that allow the soil to strike through the apertures and the two materials interlock together to give composite behavior. There is a high demand for geogrids in construction because they are good in tension and have an increased ability to distribute loads across a large area.

Applications:
Biaxial tensile plastic geogrid is applicable to the reinforcement of various dikes and subgrade, slope protection, tunnel wall reinforcement, permanent bearing foundation reinforcement of large airports, parking lots, docks and freight yards, etc. a. Bidirectional geogrid is used to increase the bearing capacity of subgrade and prolong the service life of subgrade. b. Bidirectional geogrid is used to prevent road (ground) surface collapse or crack, and keep the ground beautiful and tidy. c. The biaxial geogrid is used for convenient construction, saving time and labor, shortening the construction period and reducing the maintenance cost. d. Bidirectional geogrids are used to prevent cracks in culverts. e. Bidirectional geogrid is used to strengthen soil slope and prevent water and soil loss. f. Bidirectional geogrid is used to reduce the thickness of cushion and save cost. g. Bidirectional geogrid is used to support the stability of grass planting mesh pad on the slope and greening environment.
