  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • 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 ...

  • 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 ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...

  • Synthetic turf system solves landfill erosion challenge

    After four years as landfill district manager for IESI Corp., Delaney Lewis was discouraged. Although one of the Louisiana landfills for which he was responsible exhibited ideal geology, the soil characteristics were not conducive to side slope maintenance. The soil of the LaSalle/Grant landfill was highly erodible, exhibited a high plasticity index and had a natural pH of 4.0. ...

  • 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 ...

  • Canal sealing with Bentofix case study

    After the first pilot project installation of a geosynthetic clay liner (GCL) in a 1 km long section of the Havel-Oder-Waterway in 1997/98, approved by the local German Water and Ship Authority a second project followed shortly after. In a 500 m long section of the Dortmund-Ems-Canal a newly developed innovative GCL was installed under water. The installed GCL was Bentofix BZ 13-B, a ...
