What is Geogrid?
Geogrid is a kind of main geosynthetics. Compared with other geosynthetics, it has unique performance and efficacy. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrids are divided into four categories: Plastic geogrids, steel plastic geogrids, glass fiber geogrids and glass fiber polyester geogrids.

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.
