Leak test for more safety and a precise status quo.

Don't leave anything to chance and get certainty about the condition of your roof with our leak test. With our RAL GZ-717 and ISO certified location procedures, we check your flat roof for leaks using the latest technology.

Independent, objective, certified - the SLD 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 SLD 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 SLD 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 SLD 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.

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

Regular leak testing of your flat roof is important to prevent damage and keep leaks at bay from the outset. Only an absolutely reliable leak test will give you certainty about the condition of the roof surface and the status quo of the waterproofing. The SLD methods for flat roof leak testing, which have been tried and tested thousands of times in practice, allow pinpoint leak detection that gives you transparency.

We recommend our R.O.S.I. (Read Out Sensor Information) moisture monitoring system to permanently check the tightness of a flat roof. With this innovative method, you always have an easy and convenient digital overview of the exact moisture values of your flat roof in addition to the leak test. At SLD, you will find various measurement methods based on the SLD (Sensor Leak Detection) method.
