Leak Location Services, Inc. (LLSI) pioneered commercial electrical leak location technology and remains the industry’s most trusted independent testing provider for geomembrane liner integrity surveys. Since 1980, LLSI has set the global standard for geomembrane leak detection, helping owners, engineers, and regulators protect the environment, maintain compliance, and reduce long-term risk.
WHAT WE DO
Leak Location Services, Inc. specializes in electrical leak location surveys used to verify the integrity of geomembrane liners in critical containment systems. Our proven methods apply a controlled electrical current to detect breaches in liners that are invisible to visual inspection alone.
Geomembrane integrity testing is essential for environmental protection, regulatory compliance, and long-term asset performance. Even small leaks can lead to groundwater contamination, costly remediation, and regulatory penalties if left undetected.
As a fully independent leak detection provider, LLSI operates without conflicts of interest. We are not affiliated with geomembrane manufacturers or installation contractors, ensuring unbiased results you can trust. Our LLSI leak location services are compatible with all geomembrane types, including HDPE, LLDPE, PVC, and reinforced liners, across a wide range of applications.

FREQUENTLY ASKED QUESTIONS
What is the electrical leak location?
Electrical leak location is a testing method that uses electrical current to detect and locate holes in geomembrane liners.
How sensitive are your surveys?
Our methods can detect leaks as small as 1 mm, depending on survey type and site conditions.
Do we need to drain our pond or facility?
In most cases, no. Water surveys allow testing without draining operational facilities.
How long does a survey take?
Survey duration depends on liner size, access, and method, but most projects are completed efficiently within days.
What’s the difference between bare liner, water, and soil surveys?
Each method is designed for specific construction stages and cover conditions.
Are you independent from manufacturers or installers?
Yes. LLSI is a fully independent leak detection provider.
What areas do you serve?
We provide services worldwide, with projects completed in 28 countries.
