protective liner Applications

  • PEHD membrane sealing systems for landfill surface liners

    Unlike base liners, surface liners are not buried at some point under many metres of waste and instead are usually protected over the course of many years only by a 1-metre thick mineral layer. As a result, there can be uncertainty about the integrity of their leak-proofing characteristics, particularly if the land is subsequently used for other purposes; however, at the same time, repairs are also possible at reasonable cost if the location of any damage can be established.

    Environmental solutions for the geomembrane protection

    High-Strength Protection of Geomembrane Liners. As a protective cover for geomembranes for closure caps and stormwater ponds, the GEOWEB system prevents liner damage and degradation. With infill confined in the GEOWEB system, slopes can be designed steeper while maintaining strength and integrity, even when subjected to settlement - common in landfills.  The landfill cover system can be designed as a vegetated, aggregate armored, or concrete solution that remains flexible.  GEOWEB liner protection is a ‘complete solution’ including integral tendons and ATRA tendon load transfer clips.

  • Protection and Filtration for Industry and waste areas

    Geotextiles enhance both drainage and lining systems in environmental applications. In the large industry of waste containment, geotextiles are used to protect and cushion landfill liners and landfill capping systems, and they are used as critical components of geocomposites such as geocomposite drains and geosynthetic clay liners. Heavyweight, needle-punched nonwovens are use as cushion/protection for landfill and pond liners to keep adjacent stones in overlying or underlying drainage layers from puncturing the impermeable liner.

    Airport environmental protection solutions for the deicing / fuel containment

    Stabilization and Containment of Airport Fluids. Airports take careful measures to capture, contain, and treat deicing fluid and fuel runoff. In capturing the deicing fluid, the GEOWEB system stabilizes the pavement aggregate base layer and stores the deicing fluid in the contained aggregate voids. Stormwater containment basins built with impervious liners prevent infiltration of jet fuel and other contaminants into the groundwater. The GEOWEB system covers and protects geomembranes from puncture and solar degradation.

    Environmental solutions for the stormwater & wastewater industry

    Design high-performing, ‘low environmental impact’ GEOWEB channels for stormwater conveyance, as well as for erosion protection of containment facilities.  Protect impervious liners in lagoons and detention basins, preventing degradation and contaminant leakage.  With the GEOWEB system, channel and basin designs can be customized for each project with vegetation, aggregate or concrete infill, offering more economical solutions than rip-rap, gabions or reinforced concrete systems.  The GEOWEB system’s high-density polyethylene (HDPE) material is highly resistant to acids and bases so is ideally suited to withstand harsh chemical environments.

  • Water Containment

    Polymeric liners are prone to puncture by inclusions within the underlying soil. Thick, non-woven geotextile can be used to give protection to liners during installation. Often the upper slopes are exposed to damage and it is a good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete substance can be used to achieve a hard landscaped appearance. Our product will protect the liner from puncture whilst also providing a degree of slope stability.

  • Separation and filtration for urban areas

    In urban areas can geotextiles be found in most diverse applications. The geotextiles are being used in access and paved roads, sport fields, riverbed protection, drainage trenches and pond liner protection. The geotextiles are also being used in vertical drainage applications. Groundwater and excess rainwater can be controlled well when geotextiles are properly used. More and more floods cause serious damage to urban areas.
