Detecting defects in geomembranes of landfill liner systems: durable electrical method

Abstract Monitoring the geomembrane’s integrity becomes an essential part of recent quality assurance and quality control programs in order to guarantee an optimal performance of liner barrier. However, the existing electrical methods of leak detection for landfill barriers are generally expensive and allow only a temporary detection of geomembrane damages. Authors suggest a novel permanent electrical leak detection method for landfill barrier. Compared to existing methods, the proposed electrical circuits method (ECM) which is based on the installation of large parallel electrical circuits over the landfill site appears more cost effective and more affordable.
