  • 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 ...

  • Geosynthetic frost & salt barrier

    Terram FSB (Frost and Salt Barrier) has been successfully used to mitigate the effects of frost heave and salt damage for a road and rail project in the wetlands of western Kazakhstan. In the wetlands of western Kazakhstan the weather is characterised by very low temperatures in the winter (down to -400C) and high temperatures in the summer (up to +400C). The nature of the ...

  • CBR Strength (Puncture) of Geosynthetics

    While there exist many types of mechanical tests for use on geosynthetics, most seem to be more suitable for one type of system or another. This paper focuses on a test which may have widespread applicability to assess the strength of all types of geosynthetics. It is the forcing of a 50-mm (2.0-in.) diameter plunger through a horizontally fixed geosynthetic of 150-mm (6.0-in.) diameter. Such ...

  • Geosynthetics in the Volgermeerpolder - case study

    The Volgermeerpolder (NL), which was once a landfill site for heavily polluted household and industrial waste, has been cleaned up and turned into a nature reserve. This is the largest soil remediation operation in Dutch history. With the aid of TenCate Geotube, clean sludge was converted into a natural cap (a layer of clean soil) on top of the seal. TenCate GeoDetect is used to monitor the seal ...

  • 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 ...

  • KTK landfill capping - geosynthetic lining

    Landfill capping works are currently ongoing at KTK Landfill, Kilcullen, Co. Kildare to complete the final capping works at the facility. The capping area of the project is approximately 93,000m2 with Lining Technology providing lining crews and an excavator for the supply and installation of both smooth and double textured LLDPE liner. Works also involved sealing around existing gas wells and ...

  • Geosynthetics for a green appearance case study

    At the end of September, TenCate Geosynthetics North America introduced TenCate Miramesh SG. This is an open-mesh biaxial geotextile in which synthetic turf fibres have been integrated. It has been designed specifically to be a face wrap material for steepened slope applications and to provide an instant and permanent green appearance. The synthetic turf fibres provide an extra layer of UV ...

  • Rampere landfill capping - geosynthetic lining -case study

    Landfill capping works are currently ongoing at Rampere Landfill site, Baltinglass, Co. Wicklow for Wicklow County Council. The capping area of the project is approximately 7,500m2 with Lining Technology providing lining crews for the supply and installation of a double textured LLDPE liner and both gas and drainage collection geocomposites. The first phase of the capping works have been ...

  • 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.” ...

  • 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 ...

  • 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, ...

  • Taking Geosynthetics CQA To - New Heights - Case Study

    For years, the geosynthetics Construction Quality Assurance (CQA) industry has struggled to find a cost-effective, accurate, and sustainable solution to data collection, validation and review. Since the inception of geosynthetics CQA, the challenge with CQA has been to obtain all the required data in a logical, efficient and error free manner while insuring that the project construction and data ...

  • Laboratory Testing Apparatus for Slopes Stabilized by Anchored Geosynthetics

    A laboratory testing apparatus is described for examining slopes subjected to seepage and stabilized by anchored geosynthetics (AGS). The AGS technique can increase the stability of cohesionless slopes such as coastal dunes against surficial erosion and shallow mass failure caused by wave action and seepage forces. In the AGS, a geosynthetic fabric is placed on the face of the slope and tensioned ...
