OUR METHODS

Acoustic Leak Detection
Utilising high-sensitivity acoustic equipment, we detect the distinct sound of water escaping under pressure. These advanced sensors pick up vibrations that are often far beyond the range of human hearing, allowing leaks to be pinpointed with remarkable accuracy.
When water or gas escapes from a pressurised pipe, it produces a unique acoustic signature that travels through the pipe walls and surrounding materials. By analysing these sound patterns, we can locate leaks even when they are hidden deep underground or beneath concrete, paving, and landscaped areas.
This precise, non-invasive method minimises disruption, and helps protect valuable infrastructure.

Hydrogen Gas Tracing
For more complex or non-pressurised systems, we use hydrogen gas tracing - a cutting-edge technique in leak detection. This safe, non-toxic tracer gas is introduced into the pipework, escaping through even the smallest leak points. Our advanced detection equipment then pinpoints the exact location with minimal surface disruption.
Locator Guys is proud to be at the forefront of this method in Canterbury, applying innovative techniques that continue to set the standard in non-invasive leak detection.
