  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • Interest Growing in Mining Applications for Geosynthetics

    Some 40 percent of the geosynthetics manufactured today are used by the mining industry, according to one estimate, and there are predictions that figure will increase as the industry continues to adopt mining technologies that help improve efficiency and protect the environment. Jack Caldwell, an engineer at Robertson GeoConsultants, has gone as far as to say, “We believe that ...

  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Watch your Language! Geosynthetics vs Traditional Materials

    During GeoAmericas 2016, Dr. Neil Dixon’s sustainability keynote touched upon many topics for the future of geosynthetics. While sustainability drove most of the lecture, a few of his ideas simply approached how the field positioned itself in the marketplace. He suggested, for example, moving the field away from isolating language like “versus traditional materials.” ...

  • Landfill Capping Systems: An Introduction to Options

    Geomembranes, predominately linear low-density polyethylene (LLDPE), have been used for landfill caps for decades. Waste Management World has noted how,” Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.” Currently, there are four commonly used options for landfill caps, each with ...

  • Performance assessment of deformation behaviour of landfill barriers at the onset of differential settlement

    The present study focuses on the performance of various impervious barriers of cover systems subjected to differential settlements. Various impervious barriers, namely Compacted Clay Liner (CCL), Geosynthetic Clay Liner (GCL) and Fibre Reinforced Clay Liner (FRCL) were subjected to differential settlements artificially in a centrifuge using hydraulic trap-door system. Distinct delay in water ...

  • 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 ...

  • The Lighter Side of Geomembranes

    Geomembrane installations often cover substantial areas. Landfill cells pose enormous footprints. Oil and gas pits, industrial processing ponds, and wastewater containment ponds are large installations too, and each year they tend to be built a little larger. The scaling up of these facilities is not just a matter of achieving better operational economics for the ...
