The downside is limited backup heat, which could mean running out of hot water. There are three basic mechanisms that explain moisture accumulation in basements: Water can enter a basement or crawlspace in liquid form—through cracks in the walls, cracks in the slab, or the crack at the perimeter of the slab. Water vapor can enter a basement or crawlspace by evaporating from the interior surface of a damp wall or slab.Air conditioning can also create condensing surfaces. The same phenomenon can happen in reverse in the summertime. Let’s say the outdoor air is 85°F and the relative humidity is 75%. When outdoor air leaking inward contacts a surface below about 76°F, the moisture in the air will condense.
