Ensuring a leak-free construction project
Liner integrity surveys, also known as geoelectric leak detection, is a method of verifying the quality of installed geomembranes by locating leaks. Leaks can be found both before and after cover material placement. Many regulatory agencies are adding leak detection as a requirement for new construction. Liner integrity surveys can save our clients a substantial amount of time and money by identifying seaming failures, punctures, cracks, and tears in containment systems. GLA’s leak detection team has over 60 million square feet of experience.
