Controlling rain and ground water are the single most important factors in the design and construction of durable buildings and in the control of mold. Mold problems cannot exist without water problems. No water problems, no mold problems. The most important water problems to address are rain and ground water.
Water management techniques are used in the design and construction of building enclosures to control rain and ground water.
This guide presents a variety of recommendations for minimizing water intrusion into homes. These recommendations are not intended to apply to every conceivable situation but are intended to illustrate principles. This guide addresses water in the liquid form — rain water and ground water. This guide is not intended to address water in the vapor form transported by either air flow or diffusion.
