  • 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 ...

  • In-Plane Flow of Four Geosynthetics for Landfill Drainage

    The in-plane flow behavior of four geosynthetics, including three geonets and one geocomposite, for landfill drainage applications was investigated. Laboratory testing was performed to evaluate the effect of boundary material (cover material), hydraulic gradient, applied normal compressive stress, and time on the flow rate. The boundary materials investigated were a geomembrane, geotextile, sand, ...

  • 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 ...

  • What the Build America Bureau Means for Geosynthetics

    The Geosynthetic Materials Association anticipates higher demand for geosynthetics on the heels of the Fixing America’s Surface Transportation Act, or FAST act, and the recent addition of the Build America Bureau. The new group was created to support the $305 billion FAST Act, which provides long-term funding for U.S. infrastructure planning and ...

  • 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.” ...

  • 2000 IFAI award mud lake dam liner cover, Gardnerville, Nevada

    Situated at the base of the United States' picturesque Sierra Nevada range, the reser-voir at Mud Lake Dam, Gardnerville, Nev., was built using horse-drawn scrapers and steam shovels more than 100 years ago as an earthen dam. No longer meeting the safety standards established by the Dam Safety agency of the State of Nevada, re-habilitation was deemed necessary, A cost-effective alternative to the ...

  • Hydraulic conductivity of compacted clay liners permeated with inorganic salt solutions

    Due to their low permeability, geosynthetic clay liners (GCLs) and compacted clay liners (CCLs) are the main materials used in waste disposal landfills. The hydraulic conductivity of GCLs and CCLs is closely related to the chemistry of the permeant fluid. In this study, the effect on the hydraulic conductivity of clays of five different inorganic salt solutions as permeant fluid was ...
