Leak Detection Experts

A comprehensive leak detection service is available to Insurers, Loss Adjusters, Builders, Plumbers, Maintenance Managers, Facilities Management companies and homeowners to trace the location of water leaks. Such leaks may be visible in a variety of positions within a property, but originate from another area that is often hidden within the buildings structure.

Following the detection of the source of such leaks, a full remediation programme is also provided to restore both domestic and commercial properties back to their original condition, with minimal disruption to the work or living environment.


Thermal Leak Detection

A variety of specialist equipment is required for locating leaks from pipes hidden in structural materials. Perhaps the most commonly used is a thermal imaging camera which works by looking for differentials in surface temperatures, and will show leaking water at a different temperature to the other mass of building material (eg. a wall or floor slab). The initial survey would be undertaken using a Thermal Imaging Camera. These cameras are able to identify very small differences in temperature on the surface of different materials. This allows us to identify pipe runs that are buried in sub-floors and other areas hidden within the building structure. One of the main advantages of these cameras is that they are non-invasive and the survey can be undertaken causing minimum disruption very quickly, often avoiding major excavation work.

Acoustic Testing

Thermal imaging is not always appropriate for the conditions within the building structure. On occasions pipes can be very well insulated or buried deep in structural materials so that a change in temperature can not be identified at the surface. If this process is unsuccessful we switch to using specialist acoustic listening devices. When a pressurised water pipe is damaged the water leaks out into the surrounding ground which causes the pipe and surrounding material to vibrate at the exit point. By using sophisticated ground microphones we can trace and pinpoint the location of the leak.

Leak Detection Using Tracer Gas

This is a slightly more involved process. Water is drained from the suspected system and a tracer gas is introduced under pressure to the system. The gas is made up of 95% nitrogen and 5% hydrogen. Hydrogen being the smallest and lightest molecule will escape from the pipe at the point of the leak and make its way to the surface where it can be detected by a sensitive gas detector. The advantages of this particular mixture of gas are that it is non flammable, non toxic, non corrosive and does not damage the environment in any way.

Where there’s water damage, there’s always a risk that mould will start growing. In fact, you only have 48-72 hours to get your property dry. That’s not a lot of time, and it will be difficult to do without professional drying equipment that is used correctly. The sooner you can get started recovering your property, the better your chances of a simpler, less expensive restoration.

Unless you have access to professional flood damage equipment and experience using it, Here at Rainbow International, we would not recommend it. A professional restoration can prevent mould growth by quickly and effectively removing water and humidity using professional equipment that is specifically designed for this type of damage recovery.

While you are waiting for our professional flood damage team to arrive, here are a few things you can get started on:

    • Safety first – if the water damaged areas include electrical appliances, stay out of the area. Do NOT put yourself or anyone else at risk of electrocution.


    • You need to stop the flow of water. If there is a burst pipe, turn off the water mains from the stop clock. If there is a leak from the roof, put a container under it to catch as much water as possible.


  • Remove light pieces of furniture, electronics or other belongings out of the path of the water, if safe to do so.
