What is Geogrid?
The use of unidirectional grid can enhance the subgrade of the project, reduce the loss of subgrade materials and cause unnecessary subgrade deformation and cracking, so as to effectively prevent the diffusion load, bear greater bearing load, improve the stability and bearing strength of the subgrade, and prolong the service life. Biaxial geogrid biaxial tensile plastic geogrid is a kind of high-strength geogrid formed by extrusion and then longitudinal and transverse stretching with polypropylene as the main raw material. It can also improve the bearing capacity of the soil, reduce the pressurization of external forces, reduce the cost, have a long service life, and save the cost. It is the first choice for engineering projects. Its product advantages can also be used in subgrade reinforcement, slope protection, parking lot, wharf, airport, highway, etc., which can maintain and enhance geological functions effectively and long-term.

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.
