- The biaxial geogrid is made of macromolecule polymer through extruding, sheet forming, holes punching longitudinal and transversal stretching. This kind of material exhibits great tensile strength at both longitudinal and transveral directions, such structure can also provide an ideal chain system for bearing and spreading the force in the soil, which is suitable for permanent reinforcement of large-area foundation.
- Enhance the slope, and prevent soil erosion;
- Reduce cushion thickness, and save cost;
- Keep the stability of the slope of grass mat for green environment;
- Replace metal net to be used as the top net in the coal mine.
