Independent, objective, certified - the NIS flat roof leak test

Are you about to have a building inspection completed or are you currently having a commercial building including a flat roof renovated? Then testing your flat roof for leaks should be a top priority. In this way you can prevent leaks or detect them early and keep damage to a minimum. The NIS leak test ensures more safety on your flat roof. With the dry detection method HV-SLD and the wet detection method LV-SLD, we find leaks with pinpoint accuracy.

Both procedures are RAL and ISO certified, so you can be on the safe side when you decide on the NIS leak test. With our objective test report, you receive reliable evidence of the condition of your flat roof on the specified test date. Since the leak test for a flat roof should be carried out as early as possible, we recommend that the test should ideally be carried out before construction acceptance or immediately after renovation work.

Get certainty thanks to the HV-SLD leak test.

Only the professional and contract-neutral inspection of a flat roof brings a secure and objective status quo about its true condition. Through NIS as an independent expert for flat roof testing in the industrial and commercial sector, you receive confirmation that the flat roof has been carefully and completely tested for its function.

Our dry location method HV-SLD is suitable for leak testing of non-conductive flat roofs and all types of seals.

The HV-SLD procedures allow a non-destructive view.

In this process, our experts check your flat roof for leaks using an electrical sensor connected to an HV-SLD module. In the event of leaks, the HV-SLD module that our technicians carry with them emits acoustic and visual signals. Using our HV-SLD leak test, leaks on a flat roof are located precisely and non-destructively and faults in the sealing layer are detected. This significantly speeds up necessary repairs.

Combine our leak testing for flat roofs with our innovative R.O.S.I. Sensor technology to additionally obtain a non-destructive insight into the roof layer package.

Eine regelmäßige Dichtigkeitsprüfung Ihres Flachdaches ist wichtig, um Schäden zu vermeiden und Undichtigkeiten von Beginn an fernzuhalten. Nur mit einer absolut zuverlässigen Dichtheitsprüfung bekommen Sie Gewissheit über den Zustand der Dachfläche und den Status quo der Abdichtung. Die tausendfach in der Praxis bewährten NIS Verfahren zur Flachdach-Dichtigkeitsprüfung erlauben eine punktgenaue Leckortung, die Ihnen Transparenz gibt.

 

Um die Dichtigkeit eines Flachdachs dauerhaft zu kontrollieren, empfehlen wir Ihnen unser Feuchte-Monitoringsystem R.O.S.I. (Read Out Sensor Information). Mit diesem innovativen Verfahren haben Sie zusätzlich zur Dichtigkeitsprüfung die exakten Feuchtewerte Ihres Flachdachs immer einfach und bequem digital im Blick. Bei NIS finden Sie unterschiedliche Messverfahren nach der SLD (Sensor Leak Detection) Methode.

With NIS, roofers always play it safe.

"Thanks to the NIS inspection protocol, we have reliable and contract-neutral proof of the work we have done. Our customers can be sure that the roof waterproofing is intact."
