NIS leak detection. Trust the specialists.

A flat roof is one of the most stressed elements of a structure and therefore requires special attention. Leaks are difficult to locate without the appropriate technology and are often only discovered when water enters the building. Cost-intensive and lengthy restructuring work is the result. The certified and non-destructive NIS leak detection finds damaged areas and leaks as they occur - precisely and before they become noticeable. At your request, the damage can be repaired immediately.

Precision and high-tech bring every leak to light.

Professional and non-destructive leak detection and moisture measurements using our certified measuring methods help avoid cost-intensive restructuring work and extend the service life of your flat roof. Already in the run-up to the test, a unique classification procedure for flat roofs (RTRS) can provide you with an initial forecast of the accuracy of the test.

All leaks and potential weak points are detected with pinpoint accuracy, documented in a detailed test and measurement report and presented as a visual work plan. Benefit from our know-how and secure the long-term value of your property with NIS leak detection by our experts.

With NIS, you leave nothing to chance.
