Non-Invasive Technology Finds Hidden Water Leaks Fast
The Importance of Accurate Water Leak Detection in Commercial and Residential Buildings

Water leaks are a significant threat to the structural integrity and safety of both residential and commercial buildings. For property owners, insurance companies, loss adjusters, and local authorities a hidden water leak is far more than just an inconvenience. If unnoticed, water leaks can escalate into costly repairs and claims. In fact, the longer a leak remains undetected, the more severe and expensive the resulting damage becomes.
In this context, a fast, efficient, non-invasive solution for water leak detection is essential.
The Hidden Dangers of Water Leaks
Water leaks, particularly those hidden behind walls, under floors, or beneath concrete surfaces, can be extremely challenging to identify without the right tools and expertise. The most insidious leaks can go unnoticed for long periods, causing slow, but steady property damage, including rotting wood, mold growth, and the deterioration of walls and ceilings. Water leaks can appear in a variety of places throughout a building, often in areas that are difficult to access or see with the naked eye. Below are some of the most common places where water leaks can occur in both commercial and residential properties:
- Water Mains Leaks
- Leaks in Central Heating Systems
- Underfloor Heating Leaks
- Leaks in Drainage and Sewer Pipes
- Leaks in Swimming Pools or Spa Systems
Identifying the precise location of these leaks is crucial before any surface disruption becomes necessary.


A Non-Invasive Solution: Tracer Gas Technology
Leak detection with hydrogen tracer gas is a proven, non-invasive method for finding hidden water leaks. When injected into a system, Forming gas (5% hydrogen and 95% nitrogen) has the ability to escape through the smallest openings. This is why it is ideal for detecting leaks in hard-to-reach places, such as under floors, within walls, or even beneath concrete slabs. The hydrogen gas rises to the surface and can be easily detected with specialized instruments. This approach ensures that leaks are identified with pinpoint accuracy, no matter how concealed or difficult to access they may be.
Water leaks sometimes require tenants to vacate properties during repairs, leading to inconvenience, loss of income, and potential business interruption for landlords. Non-invasive leak detection minimizes disruption, allowing repairs to proceed more efficiently and with less impact on occupants.
The Sensistor® XRS9012 Hydrogen Leak Detector is specially designed for this application. The process starts by injecting the tracer gas into the system where the leak is expected (e.g., water system, pipes, radiators). Allow time for the tracer gas to thoroughly travel throughout the system. Depending on the length and complexity of the system, this could take several minutes to an hour. Use the leak detector’s hand probe to search for leaks. The unique sound signal and the LED indicators on the instrument display alert the operator when tracer gas escaping from the leak is found. This way leaks can be narrowed down and pinpointed fast. Pinpointing can normally be done within a few hours depending on the depending on the complexity of the system and the accessibility of the pipes (e.g., under floors, behind walls).
