Moisture mapping is a crucial technique for assessing and controlling moisture levels in buildings. It involves measuring moisture content in building materials to determine areas with excessive moisture that could lead to damage and health concerns. Acceptable moisture levels are essential for maintaining a healthy and durable indoor environment.
The acceptable range for moisture levels in building materials varies depending on the material and environment. However, as a general rule, moisture content should not exceed 16% for gypsum wallboard (drywall) and 19% for wood. These levels help prevent mold growth, structural damage, and other moisture-related issues.
Normal moisture readings for drywall typically fall between 6% and 12%. Readings above 16% indicate excessive moisture that can lead to problems. Moisture sources can include leaks, condensation, or improper ventilation. Identifying high moisture areas through moisture mapping allows for targeted moisture management and mitigation.
