Leak Location Services, Inc. Geomembrane Liner Leak Detection for Landfills, and Surface Impoundments. The personnel qualifications of Leak Location Services, Inc.

The qualifications of LLSI for performing geomembrane leak location services are unrivaled in the industry. The present eleven members of LLSI have a combined total of more than 103 years of commercial geomembrane leak location experience. A list of projects in which LLSI has performed geomembrane leak location services would include more than 1,900 leak location surveys and more than 247,000,000 square feet of survey. In the last three years we performed 473 geomembrane leak location surveys including 4,260 leaks found in more than 97,000,000 square feet (2,242 acres) of surveys. LLSI has provided leak location services in 46 states, six provinces, and 23 countries. The principals of LLSI began the development of the geoelectric leak location method in 1980 and the first commercial leak location survey was performed in 1985. are unmatched in the world. Our only business is geomembrane leak location services and we maintain excess staff to respond quickly to project requirements and to perform large leak location surveys quickly and without delay. We manufacture most of our own equipment and have several sets of leak location equipment so equipment malfunctions will not result in project delays. This unrivaled staffing and experience will ensure that leak location work will be completed successfully with efficiency and speed.

When a lined pond is already operational, “empty the whole thing” isn’t exactly an appealing first instruction.

Fortunately, it isn’t always necessary.

LLSI performs ASTM D7007 water-covered geomembrane surveys for ponds, tanks, and impoundments. The method uses the water itself as part of the electrical leak location process, allowing technicians to identify liner breaches while the facility remains filled.

That can make leak investigation considerably more practical for active facilities.

Maybe the water level is behaving differently.
Maybe monitoring data changed.
Maybe operations simply tell you something isn’t right.

Once a lined facility has a suspected leak, the conversation quickly shifts from “Do we have a problem?” to “Where is it?”

LLSI provides electrical leak location for operational containment systems and maintains rapid-response capacity for emergency leak detection.

Because searching an entire liner blindly isn’t much of a plan.

🚨 When leak location can’t wait for the next convenient opening, reach LLSI’s emergency line at 844-344- (5325).

A geomembrane can look perfectly normal from several feet away.

That doesn’t necessarily tell you what’s happening across every square foot.

Electrical Leak Location uses the liner’s insulating properties to identify areas where electrical current is passing through a breach. That can help locate punctures, tears, seam defects, and other damage that visual inspection alone may miss.

For containment systems, knowing where the problem is can be far more useful than simply knowing there might be one.

Fresh water isn’t the only liquid found above geomembranes.

Industrial containment can involve brine and liquids containing varying chemicals, which naturally raises an important question:

Can electrical leak location still be performed?

Depending on the project conditions, yes. LLSI has experience surveying facilities containing liquids beyond ordinary water.

And this is exactly why describing the actual site conditions matters when planning a survey.

Liquid chemistry. Liner configuration. Depth. Access. Conductive media.

The more the survey team knows beforehand, the better the project can be evaluated.

There’s a short period in a containment project when something incredibly useful is true:

The geomembrane is installed, and you can still get to it.

Before protective soil, drainage material, or water changes the site, an exposed liner provides an opportunity for electrical leak location and, when a defect is identified, direct access for repair.

That makes the timing of a Bare Liner Survey worth thinking about before the construction schedule reaches that stage.

Not because anyone expects something to be wrong.

Because if something is found, this may be one of the easiest times to deal with it.

A filled containment pond doesn’t automatically mean you missed your opportunity for electrical leak location.

In fact, water can become part of the testing environment.

LLSI performs electrical leak location surveys on water-covered geomembranes, with the survey approach selected around the depth and conditions of the facility.

That can be an important option when emptying a pond would be expensive, disruptive, or simply impractical.

Sometimes the question isn’t “How do we get the water out?”

It’s “How do we investigate the liner under the conditions we already have?”

When a geomembrane is already beneath soil, finding a suspected defect can feel like looking for something you can’t see in a place you don’t want to disturb.

That’s exactly why electrical leak location soil surveys are so valuable.

Rather than treating the entire covered area as one big question mark, LLSI takes systematic field measurements to identify electrical anomalies associated with potential liner breaches.

The goal isn’t unnecessary excavation.

It’s better information about where attention is actually needed.

For project owners, engineers, contractors, and CQA teams, that can make the next decision much more focused.

📞 Turn a large search area into a more focused investigation. Talk with LLSI about your covered geomembrane project at 210-408-1241.

Here’s a detail worth knowing:
Electrical leak location isn’t simply about switching on equipment and searching for a signal.

ASTM practices for these surveys are performance-based, and artificial or actual leaks can be used to verify the detection sensitivity of the equipment and field procedures.

In other words, a meaningful survey should be able to demonstrate that the method is capable of finding the size of defect the project requires, not simply say that testing occurred.

That distinction matters.

Here's the part of liner construction people don't always see.

Even with a strong QA/QC program, a completed geomembrane can be exposed to equipment, drainage materials, protective layers, penetrations, weather, and plenty of job-site activity before the facility ever enters service.

LLSI's published field experience identifies factors such as liner care and handling, environmental conditions, liner design, material characteristics, and seaming workmanship as contributors to minimizing leaks.
