  • Stabilization of steep slopes of a landfill -

    Stabilization of embankments of a landfill, covered with Geomembranes The challenge Construction of a cover of a landfill with geomembranes, in order to avoid possible penetration of water, was very complicated. The plan was to install geomembranes all around the area. Above the geomembranes a cover of local vegetated soil should be installed. Slope with a steep inclination ...

  • Why Geocells Outperform Geogrids for Road Construction

    Geocells (cellular confinement) offer a more effective and practical 3D design solution to load support challenges than multilayered 2D geogrid efforts. Geocells transfer applied loads instantaneously, delivering practical soil stabilization in a product that is fast and easy to install. How do geogrids work? Geogrids rely on rutting, displacement and lateral movement of the road ...

  • Hybrid Geosynthetic Solution for Rail Track on Expansive Clay, Geo-Americas 2016 Conference Proceedings, Kief (2016)

    Challenge – Reducing Track Maintenance on Expansive Clay Areas of expansive weak clay subgrades invariably change as a result of seasonal changes in moisture content. For rail track in these areas, the resultant heaving and shrinking causes severe degradation of rail alignment, requiring extensive maintenance. One such area is northern Israel, where the Israel Railway Authority ...

  • 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 ...

  • 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 ...

  • Q&A with Karan Jalota, Application Specialist - Roads & Rail

    In 2004, Dr. J.P. Giroud and Dr. Jie Han advanced the field of geosynthetics when they published their methodology for applying geosynthetics in unpaved structures in the ASCE Journal of Geotechnical and Geoenvironmental Engineering. The methodology has since been adopted by the Federal Highway Administration in 2008, and is considered at the forefront among industry professionals. Karan Jalota, ...
