  • Tension Creep Testing in Geomembranes

    Creep, the tendency of materials to deform over time due to applied stresses, has been a focus of the geosynthetics industry since testing first began more than 25 years ago. Creep testing methods have evolved, but the accurate assessment of tension creep (along with transmissivity) remains essential to the product evaluations of organizations considering geomembrane/geocomposite drainage ...

  • How Long Will Geomembrane Last?

    Organizations choosing from among geomembrane products evaluate options based on vital factors including containment ability, stability, and chemical resistance. So it’s only natural that they should wonder how long they can expect their chosen geomembrane to last. The answer is a complicated one. Geosynthetics magazine has reported “how all PE, whether HD or LLD, are not ...

  • ASTM D7703 - 11 standard practice for electrical leak location on exposed geomembranes using the water lance system

    Geomembranes are used as barriers to prevent liquids from leaking from landfills, ponds, and other containments. For this purpose, it is desirable that the geomembrane have as little leakage as practical. The liquids may contain contaminants that if released can cause damage to the environment. Leaking liquids can erode the subgrade, causing further damage. ...

  • ASTM D7747 - 11 standard test method for determining integrity of seams produced using thermo-fusion methods for reinforced geomembranes by the strip tensile method

    The use of reinforced geomembranes as barrier materials has created a need for a standard test method to evaluate the quality of seams produced by thermo-fusion methods. This test method is used for quality control purposes and is intended to provide quality control and quality assurance personnel with data to evaluate seam quality. This standard arose from the need for a destructive test method ...
