Foundations of a modern building are in the vast majority made of reinforced concrete. Concrete is not waterproof and ground water outside of the foundation wall or surface water that seeps in to the ground will eventually find its way to penetrate to the interior. Then it quickly becomes an interior moisture problem. To prevent this, geomembrane (pvc, hdpe etc.) or waterproofing coating is applied to the outside of the foundation. Therefore its crucial to test integrity of such layer and maintain its waterproofing properties.
SENSOR DDS® leak detection methods are quick and easy way to check the integrity of waterproofing of the foundations before its completely buried in the ground.
