Leak Location Liners: Conductive Geomembranes for Fast Leak Detection

GSE understands that sometimes leaks happen. An accidentally dropped tool, an oversized rock, or machinery used to place cover material can cause tears or holes in the geomembrane. We also understand the challenges to finding leaks easily and repairing them quickly, before problems develop which can end up costing time, money or damage to your reputation.

Finding the Leaks

Research has shown that the most effective way to detect leaks is by using Electrical Liner Integrity (ELI) surveys. The Spark testing method is used on exposed applications and the dipole method is used once the liner is covered with soil or water. According to a landfill leakage and quality assurance study (Beck, 2012), if no geoelectric survey is performed, there is a 22.2% probability of exceeding the action leakage rate (ALR), and only a 7.1% probability exists if the Dipole Method is used. However, if both an exposed geomembrane test and a Dipole survey are performed, the probability is reduced to .00001%.

Leak Location Liners

That’s why GSE developed the Leak Location Liner, a high performance geomembrane with a co-extruded, electrically conductive bottom layer. With Leak Location Liner, Spark and Dipole surveys can be conducted on both exposed and covered applications, helping to reduce the probability of exceeding the specified Action Leakage Rate (ALR). The conductive layer makes it possible to detect leaks on wrinkles and other non-conductive surfaces, and it allows the liner to be retested as often as necessary, even after cover materials have been placed.

The liner is available with an optional white surface, which reflects sunlight to lower the temperature of the liner and reduce wrinkles. An optional textured surface is available, as well, which helps stabilize the liner, and the surface characteristics of the texture can be varied on each side of the geomembrane.
