Leak Detection

 

Leak Detection

Hidden leaks can occur in any location and can be extremely difficult to detect. If left unchecked the eventual disruption and expense associated with locating and repairing the leak can be considerable. KEM prides itself on its professionalism and experience when dealing with the detection and prevention of leaks. Using state of the art techniques, KEM engineers can locate the source of any leak quickly and efficiently, minimising disruption, repair time and restoration costs.

Damp and water leak investigations can often require a wide range of inspection and testing techniques. KEM are able to select the suitable technique or combination of techniques in order to discover leaking pipes, solve water ingress, conduct flat roof surveys, check for insulation continuity, and detect under floor heating leaks and dampness problems. These techniques may include.

 

Thermography… This is the use of an infra-red imaging camera in order to observe and measure thermal energy emitted from an object. Thermography cameras are able to identify problems that cannot be detected with the naked eye.

This technique can also be used to detect moisture which cannot be detected by moisture meters.

 

 

 

Acoustic Profiling…This technique uses ground and pipe sensitive microphones in order to enhance the sound of the leak. This method is very useful in precisely pinpointing specific leaks.

This method can also detect and plot pipe routes and can calculate the exact leakage depth.

 

 

 

Correlation….Correlators are a very accurate sound testing device which are used to identify the sound frequency when a pipe is leaking. The Correlator uses two sensors located along the pipe in order to discover the exact leak location by logging the signal delay, sensor distance and sound velocity.

 

 

Tracer Gas testing…A trace gas, which is totally safe, is introduced into the pipe with the suspected leak.

As the gas is lighter it exits at the leak and makes its way to the surface where it is detected using probes gas detection probes.

 

 

 

Pipe, cable and metal Detection… In many cases the exact position of pipes and cables are unknown owing to inaccurate or nonexistent network plans.

KEM uses high performance metal detection equipment which is able to detect and trace buried pipes and cables.

 

 

 

 

Moisture meter… This is a hand held device which is able to detect the moisture content in many materials including concrete, stone, brick, fibreglass or timber down to several centimetres.

 

 

 

 

Borescope…. This is an optical tool used to look in areas which are out of sight and very hard to reach.
