HDPE Uniaxial Geogrids use High Density Polyethylene as raw material, produced through plate-extruding, punching, heating, stretching. After stretching, the messy chain constructurt will be orioutated again to get a linear state, so that the geogrid enhances its tensile strength & rigidity. By laying it into the foundation soil, the stress transmission organ will the constructed through the meshing and lock between the mesh hole and soil, to spread the partial to wide soil base, ra-pidly & efficiently. Then the partial destroy stress will be lowed down, the lifespan will be elongated.
