Non-invasive Trace & Find leak detection

Tracer gas detection is one of the most effective methods for locating concealed leaks in water pipework. Once the water supply has been isolated and the pipework prepared, a safe, non-toxic mixture of hydrogen and nitrogen gas is introduced into the system.

Because the tracer gas molecules are significantly smaller than water molecules, they escape through even the smallest defects in the pipework. Using a highly sensitive gas detector, our technician traces the escaping gas above ground to accurately identify the location of the leak.

Thermal imaging enables us to detect subtle temperature differences across floors, walls and ceilings that may indicate the presence of moisture or leaking pipework.

Thermal imaging is entirely non-contact and non-destructive, allowing us to quickly survey large areas without causing damage. While thermal imaging does not directly see water, it provides valuable information that helps narrow down the area requiring further investigation.

Acoustic leak detection uses highly sensitive electronic listening devices to detect the sound produced by pressurised water escaping from damaged pipework.

Leaks create distinctive noise frequencies as water escapes under pressure. Our specialist equipment amplifies these sounds while filtering out background noise, allowing the technician to identify the point where the leak noise is strongest.

A borescope is a compact inspection camera that allows us to view concealed spaces through a very small access point.

This enables us to visually inspect hidden pipework and building cavities without the need for extensive removal of finishes, helping confirm the presence of leaks, moisture damage or failed plumbing components while keeping disruption to a minimum.

Moisture meters are used throughout the investigation to assess moisture levels within building materials.

By comparing moisture readings across affected and unaffected areas, we can establish the extent of water migration, identify likely leak paths, and distinguish between active moisture and historical dampness.

Moisture meter readings also assist in confirming our findings and provide valuable evidence for insurance reports and recommendations for drying and reinstatement works.
