The Problem

A customer called us recently about a problem concerning the geothermal heating system in his newly-built home. He told us that there was a significant drop in pressure, and he was naturally keen to find the cause and have the problem remedied. In order to be able to pinpoint the leak, our engineers first had to inspect the pipe system under pressure. This allowed them to narrow down the area in which the leak or leaks were. In this specific case the leak was in the pipes that were running under the ground through a particular part of his property.

Because our engineers had now been able to identify the position of the leak and limit it to the pipes that ran outside the house, they now opted to use the trace gas method to determine exactly where the leak was.

The Solution

First, the engineers consulted the building plans to determine the course of the pipes. Then they used a compressor to empty the entire system.

The next step comprised flooding the pipe system with trace gas. The engineers then walked along the known course of the pipes and used a gas tracer to detect the escaping gas. The leak was under a paved area. The gas tracer measured extremely high concentrations of the tracer gas…


By using non-destructive measuring technology, our engineers are able to detect leaks in pipes that run underground, even when there are no plans or the exact course of the pipes is not known beforehand.  In such cases, the course of the pipes is first determined or located and the area where a leak has occurred is then narrowed down using, for example, the trace gas detection method.

Locating leaks can be a very costly business – it can involve having to tear up whole driveways or digging up front gardens, which have to be returned to their previous condition. But it can also be a far  less costly experience:

Non-destructive measuring technology can be used to pinpoint leaks without having to be carry out large-scale excavation work.

This once again goes to show that cutting-edge technology and the right equipment in the right hands can save you thousands of pounds and ensure that the job you have in mind is well done.
