Hi, Did a raised ranch with a moisture problem that I can't pin point. The worst part is dead center of the building in the lower living space. The carpet in this area has been cut out and there is a dehumidifier running 24/7. There is no sign of staining, repair, or replacement of any of the perimeter walls. (original rock,paneling,and trim) Is it possible that it's ground water that is permeating through the pad? If so, what do you do about it?
