High Modulus Polyester Bi-axial Geogrids

High Modulus Polyester Bi-axial Geogrids are produced with high molecular weight, high tenacity polyester yarns using a precision knitting process and then coated with a polymer or PVC coating to provide dimensional stability and offer resistance to installation damage. They are also chemically stable and appropriate for using in aggressive soil environments which pH levels from 3.0 to 12.0. Their primary characteristic is excellent creep performance with low strain and high tensile strength under constant load. These geogrids are dimensionally stable and through a uniform network of ribs and apertures provide tensile reinforcement to the surrounding soil to provide the long-term design strength (LTDS) required for each specific application.
