  • Artificial lake in Swanscombe, Kent Project - Case Study

    A former quarry for cement production is being transformed into a residential area, with 6250 homes, various shops and parks, and an enormous lake. That, in a nutshell, is the megaproject that Trisoplast played a crucial role in 2009. We lined the bottom of the nearly 18-hectares-large lake with Trisoplast to ensure there would be absolutely no risk of groundwater contamination. Exceptional ...

  • Green Roofs - Case Study

    The green roofs of the buildings are completely covered with vegetation. In event of a leakage in its sealing system, its technically very difficult or in some cases even impossible to locate and repair the leakage. For that reason we developed a Sensor DDS system which is permanently implemented into the roof design. Solution for flat roofs – SENSOR DDS technology The most ...

  • Non-Hazardous Landfill - Case Study

    Municipal solid waste landfill is site for domestic day-to-day waste disposal. Its also known as tip, rubbish dump, dumping ground, etc. Material stored at solid waste landfill is isolated from the environment by sealing layer which can be HDPE or LDPE or even PVC geomembrane. If such geomembrane leaks, the contaminant from landfill is spreading in direction of the groundwater flow. ...

  • Reinforcement and safety of the road-shoulders on a rural road - Case Study

    The challenge Most of the rural roads in Europe were built at a time where the transition of one vehicle at once was enough. Today, it is impossible to respond to the evolution of the current traffic namely to allow the transition of two parallel crossover vehicles. The vehicles are forced to move on the road-shoulders which results in the formation of serious rills alongside the ...

  • Protection of a slope along a road in a semi-arid region - Case Study

    The challenge The road enlargement works in close proximity to residential areas have created particularly steep slopes. The local soil is composed of loess, materials with well-known characteristics in contact with water. A typical rainfall curve in those very dry areas, where the heavy rains, even rare, have resulted in very serious soil erosion. ...

  • 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 ...

  • Raising Dead Ships: Derelict Vessel Removal

    One of Global’s specialties is vessel salvage – if your vessel runs aground or sinks, we’ll raise it and hopefully refloat it for you. But what happens to the thousands of old, worn out vessels that sit abandoned along the coasts and harbors? Often they sink, where they pose an environmental and navigational hazard. That’s why Washington, Oregon, California and Alaska have ...

  • PRS - Neoloy Geocell Research

    This study by Kief and Toan, published in Geotec Hanoi, surveys worldwide research, demonstrating that NPA Geocells improve layer modulus by up to x5 and reduce total costs of pavement construction by up to 20%.  The study shows that NPA Geocells are a sustainable solution for the structural base ...

  • 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 ...

  • Choosing the Right Geocell

    Not all geocells are created equal. While most manufacturers can provide similar-looking written specifications, you need assurances that the material delivered for your project is of the high quality that you expect. Important factors in the success of your geocell project include: Quality The geocell material is proven, strong, and will last ...
