Leak Detection


SES Ltd provides an experienced leak detection service to its customers throughout Ireland. Our highly experienced team have all the knowledge and equipment required to effectively detect leaks and conduct the necessary repairs. Leak detectionAs part of our service, we allow for an Initial Consultation with all clients that have a leak or suspected leak. This consultation helps us establish an overview of the problems been encountered by the client and it helps us establish the steps required to firstly locate and secondly fix leaks to save water. SES Ltd has worked with some of the largest companies in Ireland including the ESB, Kerry Group, and Element Six. SES Ltd are constantly striving to utilize all the latest methods of detection in order to provide a complete solution to their customer’s leaks.


Leaks in Plastic Pipes

In the past, finding leaks in plastic pipes such as PVC, with traditional correlators was notoriously difficult. SES Ltd have now teamed up with Echologics who are considered world leaders in producing the most advanced equipment used in leak detection due to its superior performance on plastic pipes. SES Ltd are now finding leaks where our competitors are failing. We have found leaks in PVC pipe sections over 500 Metres in length, whereas other correlators fail to find leaks in PVC sections of 60 metres. We are the only company in Ireland able to offer this service in Ireland. SES Ltd are now the Irish Distributor for their range of leak detection equipment. For more information or to organise a demonstration contact us for details.


Pipe Tracing

SES Ltd can trace both metallic and plastic piping. This is very important part of a leak detection survey. Knowing the route and distance of pipework is essential in finding leaks and carrying out repairs with the minimum of disruption. We use an Electronic Transonde for locating non metallic water pipes. The battery operated Transonde connects via an outside tap or directly at fitting. The Transonde is used to vibrate the water as it passes through it and across an internal spring system sending a minute sound wave back along the pipe which can then be located using a ground microphone. For metallic pipes a CAT (cable avoidance tool) is used to detect signals naturally radiating from metallic services.


Domestic Leaks

Leaks in heating systems are normally small and hard to find. SES Ltd use the tracer gas method to find these type of leaks. If you have a leak on your central heating system and the floors are tiled, laminated, marbled etc and you do not want to take up the whole floor searching for the hidden leak or leaks, we can help. It is fair to say that the leak/leaks are normally on the ground floor, if it was on the first floor or above you would have wet patches on your ceiling at some point. We isolate the first floor and above, then inject tracer gas into the central heating pipes; we can then trace the leak location/locations by identifying where the tracer gas rises up and by comparing the concentration levels. This method is useful for any size or type of underground pipe and does not leave any residue or require complete removal of product prior to testing. The gas mixture is made up of 5% hydrogen and 95% nitrogen and it is: inert, odourless, tasteless


Pipe Conditional Assessment

Pipe conditional assessment is a process of determining the effective remaining wall thickness of pipes laid in the ground. Metallic pipes lose thickness as a result of internal and external corrosion. Cement-based pipe types lose “effective” wall thickness by the weakening of the wall as a result of the leaching out of the cement by aggressive waters. Pre-stressed concrete cylinder pipes also lose strength as a result of the corrosion of pre-stressing steel. Plastic pipes may lose material strength as a result of mechanical fatigue and chemical attack. A direct indicator of the general structural condition of pipes is the remaining or residual wall thickness. Also, if wall thickness loss is monitored over time, the remaining service life of pipes can be estimated.
