Our Services

At Leif Koch A/S we are specialised in finding leakages, by listening to the sound of water leaking from buried water pipes. Besides finding the leaks, we also educate people, teach them how to do it themselves and supply the necessary equipment.

We provide:
  • Leakages detection
  • Pipe detection
  • Pinpointing of leakages
  • Guidance
  • Consulting
  • Instruments
  • Courses
The principle of leakage detection and what we do is simple. If there is a sound of running water, when all taps are turned off, there must be a leak. However it is not always this simple and other parameters such as traffic and surrounding noise can affect the listening process, which means that in practice the work is more demanding and know-how becomes essential.
In order to preform our best and make a precise detection of leakages, we apply several different methods in our work, such as:
  • Acoustic detection & monitoring
  • Acoustic correlation analysis
  • Measurement of pressure and flow
  • Sectioning
  • Trace gases
