Geomembrane Leak services

  • Electrical Leak Detection Surveys Service

    BHF environmental has specialised in electrical leak detection surveys since 1994.To detect and locate leaks in plastic membranes, the company uses the geco system. This application of geoelectrics is widely used as an effective tool in the process of Construction Quality Assurance in many countries, mostly for landfill applications and water ...

  • Other Services

    Leak Integrity: Studies show that nearly 75 percent of the damage found in geomembrane systems happens when the drainage/protective layer is placed over top of the geomembrane, not during geomembrane construction.

  • Bare Liner Surveys

    To avoid the logistics of flooding the geomembrane with water, the exposed geomembrane can be tested for leaks using a water puddle test. This test is used on geomembranes that are in direct contact with the supporting sub-grade or a GCL. Procedures for this method are specified in ASTM standard D-7002.

  • Soil Surveys

    Damage caused by heavy machinery while installing earth materials on geomembranes is the most significant cause of damage to geomembranes. A geoelectric leak location survey of the soil-covered geomembrane of a newly constructed landfill is a very cost effective method for finding leaks that occur while placing a protective soil cover over the ...

  • Constructions Underwater

    All of Carpi‘s geomembrane installations can be performed underwater, with technologies that Carpi started developing at the beginning of the 1990ies. The waterproofing geomembrane system can be installed on the entire upstream face, or on leaking zones, or on failing joints and cracks only.

  • Concrete Dams

    Carpi waterproofing geomembrane systems are used on these dams at the upstream face, to restore watertightness to the entire face, or at leaking zones, or at cracks.

  • Landfill Gas Surface Monitoring Services

    As USEPA's concerns over greenhouse gasses emitted from landfills increase (CFR 61, 12 March '96), I-CORP has built upon its expertise of locating leaks in geomembrane liners electrically to measure geomembrane seam strength nondestructively using infrared (IR) thermography, and by offering IR technology for rapidly and accurately mapping these ...

  • Chemical and Petrochemical Containment

    Tank farms can range in size from huge complexes in refinaries to clusters of tanks used to store heating oil or product ingredients in relatively small facilities. They all need to contain a material that is spilled or leaked before it gets into the groundwater supply. The geomembrane liner should be made from material that will resist damage ...

  • Towed Probe Survey Mode

    If the water in the geomembrane lined pond, impoundment, or tank is too deep or the water in the pond is unsuitable for personnel to wade, then the towed probe survey mode is used.  While standing on the top of the side slopes, survey personnel systematically pull the probe back and forth across the bottom of the pond along temporary survey ...
