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:
Application of biaxial geogrid: biaxial plastic geogrid is used to strengthen the subgrade of various highways and railways. Increase the bearing capacity of subgrade and extend the service life of subgrade; Prevent cracks on the pavement; Reduce repair costs; Reduce the construction period. The biaxial geogrid is applicable to the permanent foundation reinforcement of large parking lot and wharf freight yard. Increase the bearing capacity of the foundation and guard the ground against collapse, which can make the ground elegant and neat; The construction is convenient, time-saving and labor-saving. Bidirectional geogrid is applied to the secondary reinforcement of soil slope reinforced by unidirectional tensile plastic geogrid.
Construction method
Construction method of biaxial geogrid: excavate the subgrade bed, set sand cushion (height difference not more than 10 cm), roll it into a platform, and lay the grid. The longitudinal axis shall be consistent with the main stress direction. The longitudinal lap shall be 20 cm and the transverse lap shall be 10 cm. The lap joint shall be bound with plastic tape, and the paved grid shall be fixed to the ground with U-nails every two meters, The geogrid laid shall be backfilled with soil materials in time, and the number of layers of geogrid laid depends on the technical requirements.
