The foundtations of modern buildings are mostly made of reinforced concrete. Concrete in general is not waterprooft, and groundwater outside the foundation wall or surface water that gets to the ground will eventually find its way into the interior. Then it quickly becomes and internal problem with moisture. To avoid this, the geomembrane (pvc, hdpe, ldpe, liquid membrane etc.) is installed on the foundations. Therefore its necessary to test the integrity of such geomembrane to maintain its waterproofing properties.
The leak detection and localisation technologies and methods SENSOR DDS® are quick and reliable way to check the integrity of the foundation waterproofing before they are buried in the ground.
