Earthmate WALLSTRAIN® HDPE Uni-axial Geogrids are produced from high density polyethylene (HDPE) resins. The HDPE Uni-axial Geogrids are resistant to installation damage and long-term chemical or biological degradation in both dry and wet environments. It can load high tensile strains applied in one direction and its open aperture structure interlocks with fill material to transfer the loading strains from soil to geogrids. Their primary characteristic is excellent creep performance with low strain and high tensile strength under constant load.
