  • Size Effects for Multi-Axial Tension Testing of HDPE and PVC Geomembranes

    Geosynthetics may be subjected to multi-axial stress states from plane strain loading, such as dragdown along lined slopes and from out-of-plane loading conditions imposed by localized subsidence beneath waste containment cover and liner systems. The multiaxial tension test is useful in evaluating the performance of geosynthetics subjected to multi-axial stress states. However, widespread ...

  • Examining the benefits of HDPE geomembrane

    Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been in use for decades and during that time a number of studies have been conducted to test its longevity and ability to meet environmental sustainability project requirements. Here, we explore some of those studies to examine the benefits of HDPE ...

  • EPT New Report Solves Geomembrane Acronym Puzzle

    Elvaloy®, patented by DuPont in 1973 has been used as a geomembrane plasticizer for decades. It was developed to provide a solid plasticizer or polymer to replace liquid plasticizers that would make PVC flexible without concerns of plasticizer migration. That much is clear. But what is very blurry is the usage of many of the acronyms and names used in connection with this product. There is ...

  • Composite protection for slopes - Dallas Eastside Water Treatment Plant, Texas - Case study

    Geocells, geotextiles and geomembranes resolve the chronic erosion problems of a municipal levee. In 1996, consulting engineers under con-tract to the City of Dallas contacted Soil Stabilization Products Company Inc. (SSPCo) to discuss solutions for chronic problems caused by more than a dozen sliding failures per year on the outer slopes of a water treatment facility's lagoon. The facility, ...
