Detects an open seam through negative pressure.
The vacuum or negative pressure system is a non-destructive leak detection method on flat roofs. It uses a vacuum bell and a testing fluid (foam-forming material) to reliably detect and visualize leaks in the waterproofing. It is paricularly suitable for seams of welded waterproofing membranes and other small areas.
The vacuum bell is placed over the seam, and a vacuum pump is used to create a vacuum. If airs enters, this indicates a leak. Pressure changes or foam formation make damage immediately visible.
After assessing the conditions and the quality of the flat roof, our team can present you with a tailor-made and sustainable concept - safe, effective and affordable.
Leaks in the waterproofing membrane must be located, documented, and remidied quickly and reliable. We take care of that.
