Damp basements are a common characteristic of Canadian houses. Excessive humidity in basements leads to deterioration of materials and finishes, as well as the growth of mold. Living in houses with wet and moldy basements has been related to the development of respiratory illnesses. This paper reviews studies on typical basement conditions, the frequency of moisture-induced damage, and the implications of high moisture levels in basements. It describes a research project that investigated the possibility of more forgiving interior insulation treatments for basement retrofits. Wall systems that tolerate an occasional wall leak or flood would be advantageous to basements with uncertain moisture performance. Ten wall systems were tested by inducing both a wall leak and a flooded floor, and their drying performance was monitored.
