Emergency Leak Detection: 844-344-LEAK

ASTM Certified | 30+ Years Experience | Independent Third-Party Testing

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.

 

SERVICES

Bare Liner Surveys (ASTM D7002)

Water Puddle Method for Exposed Geomembranes

Bare liner surveys are conducted before a geomembrane is covered with soil, water, or aggregate. Using the ASTM D7002 water puddle method, we locate leaks as small as 1 mm in exposed liners.

This survey is ideal for pre-service inspections, helping prevent costly repairs after construction is complete. Early detection allows contractors to repair defects before protective layers or waste are placed.

Water Surveys (ASTM D7007)

Electrical Leak Location for Water-Filled Facilities

Water surveys are the most accurate method for detecting leaks in ponds, tanks, and impoundments that are already filled. LLSI performs both wading surveys and deep-water towed array surveys in accordance with ASTM D7007.

These surveys are ideal for operational facilities where draining is impractical or costly. Our methods precisely locate leaks without disrupting facility operations.

Soil Surveys (ASTM D7007)

Post-Construction Testing Beneath Soil Cover

Soil-covered surveys are performed after geomembranes have been covered with protective soil or drainage layers. This method detects damage caused during construction by heavy equipment, material placement, or settlement.

Landfill liner testing using soil surveys is critical for regulatory compliance and long-term environmental protection. LLSI’s soil surveys help owners verify liner performance before waste placement or during facility expansions.

Leak Monitoring (ELIM)

Permanent, 24/7 Geomembrane Leak Detection

Electrical Leak Imaging Monitoring (ELIM) systems provide continuous, real-time monitoring of geomembrane liners. Installed during construction, ELIM detects and locates leaks as they occur throughout the life of the facility.

Leak monitoring systems are ideal for high-risk containment applications requiring long-term protection, early warning, and rapid response.

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.
