　　Biaxially stretched plastic geogrid:

　　Biaxially stretched geogrid is made of high molecular polymer through extrusion, plate forming, punching and then longitudinal and transverse stretching. This material has great tensile strength in both longitudinal and transverse directions. This structure can also provide an ideal interlocking system for more effective force bearing and diffusion in the soil, which is suitable for large-area permanent load-bearing foundation reinforcement.
