Excess moisture that comes into your basements comes as majorly liquid water through rain and through groundwater. There are also internal activities that lead to excess moisture build-up in the air. Outside air that is humid and damp can also easily get into your basements. These are the reasons why basements find the need to remove humidity more than any other place in a home.
