High Tensile Modulus

High tensile modulus woven products are composed of high-tenacity polyester yarns that offer long-term tensile strength to reinforced soil structures such as walls, over-steepened embankments, and embankments constructed over weak subgrades. Contact your Hanes Sales Representative to discuss selection of these geotextiles.
