From mining and industrial facilities to landfills and wastewater basins, geomembrane liners are essential for isolating hazardous materials and protecting the environment. However, even minor defects – pinholes, seam weaknesses, or installation damage – can compromise containment. Once covered by soil, water, or ballast, these breaches are almost impossible to detect without the right technology.
Conventional leak detection surveys often face limitations: unreliable results over dry or frozen subgrades, false positives near seams, and incomplete testing in areas with wrinkles or uneven contact. Engineers need a more reliable, repeatable, and cost-effective method for verifying liner integrity – both during installation and throughout a site's lifecycle.
The GSE® Leak Location Suite delivers a comprehensive, field-proven solution for locating geomembrane leaks using advanced electrical leak location (ELL) methods. The system combines a conductive-backed liner with specialized tools that enable efficient testing across both exposed and covered applications.
At the core of this suite is the GSE Leak Location Conductive geomembrane – a high-density or linear low-density polyethylene liner co-extruded with a conductive bottom layer. This design removes the need for a separate conductive substrate and enables reliable testing using Spark Testing or Dipole Surveys. .
For improved installation and survey accuracy, the Iso-wedge – a patented tool developed by Solmax – prevents conductivity breaks at welded seams and eliminates false positives. The S-100 Spark Tester, equipped with three electrode attachments, allows for precise leak detection across complex surfaces, including seams, wrinkles, and vertical panels. GSE Leak Location Suite can significantly enhance post-installation leak testing, providing an essential safeguard to the environmental containments.
