PP Biaxial Geogrid

The PP Biaxial Geogrid has the appearance of a square network structure. It is a high-strength geotechnical material that is extruded and stretched longitudinally and transversely. The material has high tensile strength in both machine and transverse directions. Because of its high longitudinal and transverse tensile strength, it is widely used in soft foundation reinforcement treatment.
