This six-hour course examines the science of moisture intrusion, movement, and consequences; analyzes guidance provided by building codes and standards; and assesses the performance of moisture-resistant foundations, wall systems, and roofing systems. The course concludes by examining mechanical systems that can be utilized to control moisture.

Delving into the science of thermodynamics and moisture movement, the curriculum covers how bulk water, capillary action, and vapor diffusion interact with various building materials and envelope assemblies. The course provides a thorough overview of effective mitigation strategies, including the proper use of flashing, vapor retarders, drainage planes, and ventilation techniques tailored to diverse climates. From strategic material selection to precise construction detailing, this overview emphasizes the critical practices needed to prevent mold, decay, and structural failure, ultimately promoting long-term building durability and healthier indoor spaces.
