Leak Location Liner Performance Evaluation
A new geomembrane product, Leak Location Liner, developed by GSE specifically for electrical liner integrity surveys (ELIS), enables leak detection surveys for otherwise unfeasible applications and improves leak detection sensitivity for common applications. The capability of this new geomembrane to enable leak detection surveys on the primary liner of a double-lined installation, sites with complete subgrade desiccation, holes at the peak of a wrinkle, under a seam flap, and in an area of poor contact with the subgrade were all tested and verified. In order to compare the leak detection sensitivity of a survey performed on Leak Location Liner to a survey performed on traditional geomembrane, comparative bench-scale testing on both was conducted. The ratio of a leak signal obtained on the Leak Location Liner setup relative to a leak signal obtained on the traditional geomembrane setup was calculated and is here-on referred to as the improvement factor for ease in interpreting the comparative data. This improvement factor was quantified for a spectrum of subgrade soil resistivity values by varying the moisture content of the subgrade soil. The results of comparison trials with the subgrade soil condition varying from near zero moisture content to saturation show the improvement in leak detection sensitivity as a function of subgrade resistivity when Leak Location Liner is used. The results of the testing include expected improvement factors for single-lined applications as a function of subgrade soil type and moisture content, as well as in a multitude of hole conditions.
