What is Geogrid?
Biaxial tensile polypropylene geogrid is made of high molecular polymer through extrusion, plate forming and punching, and then stretched longitudinally and transversely. The material has great tensile strength in both longitudinal and transverse directions. This structure can also provide an ideal chain system for more effective bearing and diffusion of force in soil, which is suitable for foundation reinforcement with large-area permanent bearing.
