Leak detection investigations
The goal of a leak detection investigation is always to locate the source of the leak as accurately as possible before any repair work begins. This helps avoid extensive demolition and unnecessary costs. After the investigation, the client receives a clear report of the findings along with recommendations for further actions.
Leak detection in pressurized water systems allows us to locate leaks in the water supply network quickly and accurately, without unnecessary demolition of structures. Properly carried out leak detection saves time and costs while preventing more extensive water damage.
The leak detection method is always selected based on the specific property and situation. We use multiple complementary techniques to ensure the most accurate possible result.
Water leaking from a pressurized pipe creates sound that travels along the pipe and surrounding structures. Using sensitive listening equipment, we can detect the sound of the leak through the ground, structures, or floors.
A safe hydrogen–nitrogen gas mixture is introduced into the piping system. The gas escapes through the leak point and rises through soil or structures, allowing precise detection with a gas detector—even in cases where the leak is not continuous.
The piping system can be divided into sections and tested separately using pressure. This helps narrow down the leak to a smaller area before more precise localization. Leak detection in drainage systems and inspection chambers can also be carried out, for example, by temporarily flooding the system.
