What is one method to stop moisture from entering a building?

• A. Increase indoor humidity
• B. Ensure air leaks are present
• C. Improve drainage
• D. Reduce ventilation

Answer: (C)

Improving drainage is an effective method to stop moisture from entering a building because it addresses the management of water around the foundation. Proper drainage systems, such as gutters, downspouts, and grading the landscape away from the building, help direct water away from the foundation. By preventing water accumulation near the base of the structure, the risk of moisture seeping into the building through walls or the foundation is significantly reduced. This is crucial in maintaining a dry and healthy indoor environment, as excess moisture can lead to issues such as mold growth and structural damage. The other options focus on increasing or allowing moisture into the space, either by increasing humidity levels, allowing air leaks, or reducing ventilation, none of which would effectively manage or prevent moisture intrusion into a building.
