  • Creep not a factor for Geocell load support

    An accurate understanding of creep resistance is essential to proper material selection when using polymers, and in the case of geocells, this science is being misapplied.  The definition of creep deformation is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stress.  Creep is something that creates fear and uncertainty with all ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • Case study - Log storage handling yard

    The logging yard at Canfor’s Fort St. John mill is subject to the heaviest loading operations in the worst soil conditions. Saturated peat with a CBR Cat 988H loaders weighing more than 43,000 kg, heavy hauling trucks, and other mechanical equipment created heavy rutting in the soft soil. The logs, stockpiled in huge, 6-metre high stacks, suffered from large settlement, which further ...

  • Millstone Manor Parking Lot Stabilization - Case Study

    Shallow utilities won’t get in the way of our high strength woven geotextile’s ability to stabilize this parking lot. Millstone Manor, an apartment complex located right next to the Ogden River at the base of the Wasatch Mountains, had been having difficulty stabilizing their parking areas for years. Due to its proximity to a water source and resulting soil types, the CBR ...

  • 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 ...

  • Preventing Soil Erosion - Protecting Humanity

    When discussing environmental concerns, soil erosion is not the first issue that comes into mind. The world’s media focuses on fossil fuel problems, climate change, biodiversity and forest fires, while soil depletion is less spectacular and is seldom mentioned. However, societies in the past have even collapsed or disappeared as a result of soil erosion. For centuries Easter Island was ...

  • Poor quality soil can lead to harmful impact: Stop erosion now

    Soil erosion is known as the wearing away of topsoil, leading to poor quality soil that is less conducive for plant and vegetation growth. In our series of blog posts focusing on erosion control, today we take a look at the harmful effects of soil erosion, and how they cause concerns not only to the environment, but also to human health and the economy as a whole. Poor Quality Soil ...

  • Geotextile Gravel Pavers keep lake clean in Denver - Case Study

    Denver’s City Park is an iconic symbol of the Mile High City. The oft-photographed park is home to the city’s zoo and the Denver Nature and Science Museum, as well as sports and recreational areas. In 2014, the asphalt parking lot for the Denver Pavilion inside the park was scheduled to be resurfaced. The city, with the help of StudioCPG, a landscape architecture and planning firm, ...

  • Biological regeneration of ferric (Fe3+) solution during desulphurisation of gaseous streams: effect of nutrients and support material

    This paper evaluates the biological regeneration of ferric Fe3+ solution during desulphurisation of gaseous streams. Hydrogen sulphide (H2S) is absorbed into aqueous ferric sulphate solution and oxidised to elemental sulphur, while ferric ions Fe3+ are reduced to ferrous ions Fe2+. During the industrial regeneration of Fe3+, ...

  • 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 ...

  • Cox creek spillway improvements access road, Baltimore, MD - Case Study

    GEOTERRA® mats were employed for site access roads to an outfall from a dredge material containment facility. Because the outfall is located on the bay side of a containment dike, it is considered an environmentallysensitive area and lies within Maryland’s Critical Area—the naturally vegetated area within specified boundaries of the state’s tidal waters. Low Impact ...

  • Treatment of domestic greywater by geotextile filter and intermittent sand filtration bioreactor

    Intermittent sand filtration (ISF) is an efficient system for treatment of greywater; however, the high quality of effluent and the simple set-up contrast with the high failure rate due to clogging of surface layers. The efficacy of several polypropylene non-woven geotextiles (apparent opening size from 0.10 to 0.18 mm) used as primary treatment filters to remove suspended particles from ...

  • Geotex® 4x4 used in Missouri slope failure repair project case study

    In 1993, flooding in an adjacent stream caused a slope failure along a 300 foot section of Old Highway 100 in Franklin County, Missouri. Many attempts were made over the years to stabilize the slope and roadway, and none were successful. Flooding caused the slope that supported the highway to give way and become hazardous. A porous concrete slope protection facing was used to cover approximately ...

  • Geotex® 200ST Fabric brings smooth travel to remote road case study

    Willow Creek Road is a 36-mile stretch of un-paved road. Cattle ranchers, vacationers and hunters use the road, but during wet weather it became a muddy, hazardous mess. The soil is a silty clay, and earlier attempts to use just gravel were less than successful. In addition, the nearest gravel pit is a three-hour drive, so Valley County Road Superintendent Wayne Waarvik knew he had to do more ...

  • 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 ...
