  • 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 ...

  • Geosynthetic/Soil Interface Friction Angles Using a Rotation Shear Device

    A modified rotation shear device was used for measuring interface friction angles between soils and geosynthetics. The device was modified so that a geosynthetic specimen can be attached to the upper platen. A reliable method for cutting and attaching geosynthetic specimens to the device is described. The geosynthetic mounting system is simple, strong, and easy to remove. Interface friction ...

  • Slurry Lagoon Mountmellick - case study

    Lining Tech have completed lining works to construct a cost efficient 1,000,000 gallon geomembrane lined slurry lagoon in Mountmellick, County Laois. Works included the installation of a 2.5mm smooth HDPE liner in accordance with the Department of agriculture's specification S126 for geomembrane lined slurry lagoon. Works also included the fabrication and sealing of five pipe boot details around ...

  • 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 ...

  • 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 ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Closure Options for Impoundments and Landfills

    In Kentucky, a county board votes to shut down a landfill that had long been the source of odor complaints from nearby residents. In Hawaii, residents push a city council to expedite a delayed landfill closure. Outside Beirut, Lebanon, protesters try to block trucks entering a landfill they say should have been closed a week earlier. These events, while certainly newsworthy, obscure the fact that ...
