1.Product Description
Appearance of bidirectional tension plastic geogrid is grid shape structure with near square. It uses polypropylene and high-density polyethylene as main raw materials, is pressed into plate by melting extrusion and formed by punching, heating, vertical and horizontal directional tension. The product has a large degree of stretch in both the vertical and the horizontal direction. This structure also provide an ideal interlocking system for the more effective force bearing and diffusion in the soil. It is suitable for large-area permanent bear reinforce for roadbed.
2.Product Feature
1.High tension resistance, high plane torsion resistance modulus, good creep resistance and stable chemical nature.
2.High mechanic damage resistance and durability and large friction factor with sandy stone.
3. Improve the bearing capacity of the roadbed and extend the service life of the roadbed.
4. It can decrease 30%-40% of filling thickness for reaching same effect, save cost.
