Leak Detection, Trace & Access
Water leaks can be hard to trace, both inside and outside of a property. External leaking water pipes can cause an increase in your water bills and leave an unsightly mess in your garden, drive or outbuildings. Internal pipes leaking can cause severe damage to any property, if not located and fixed rapidly.
At DisasterCare, we employ a Trace & Access service for detecting leaks. Often pipes leak within buried or hard to find parts of a building structure, behind walls, under floor slabs, and where the water manifests itself is not necessarily the point of the leak. Our technologically advanced processes pinpoint the exact location of a leak, and avoids major disruption and excavation.
Simple and effective detection of leaks through :-
- Thermal Imaging
- Acoustic Testing
- Tracer Gas
- Endoscopy
- Avoid unnecessary cost and major excavation
- Saves time, cost & disruption
- For interior and Exterior Leak detection
Acoustic Testing
Some pipes are very deeply buried or are so well insulated that thermal imaging cannot be effective. Acoustic testing can then be utilised. When a pressurised water pipe is damaged the water leaks into the surrounding ground which causes the pipe and surrounding area to vibrate at the exit point. Utilising sophisticated microphones we can trace and pinpoint the exact location of the leak.

Tracer Gas
If we are unable to detect an acoustic signal, tracer gases can be utilised. Water is first drained from the system, and a tracer gas is introduced under pressure to the system. The gas is 95% nitrogen, 5% hydrogen, and as hydrogen is the lightest and smallest molecule it will escape from the point of the leak and exit to the surface, which is detected with sensitive gas detectors. The gas used is perfectly harmless and will not damage the environment in any way.

Endoscopy
This involves looking into hidden cavities in a building structure using an Endoscope/Borescope. Inserted into a cavity by drilling a small hole it has a small camera attached to the end of the apparatus, allowing a visual inspection. Endoscopes/Borescopes are also sometimes used when direct line of sight is not possible, and this is a highly reliable method of viewing inside cavities.
