### What is Moisture Mapping? Moisture mapping is a vital process that assesses and documents the moisture content within building materials. By using specialized equipment, moisture mapping helps professionals detect and identify areas with excessive moisture that could lead to structural damage, mold growth, or other health hazards. ### Acceptable Moisture Levels Moisture levels in building materials should be carefully monitored to prevent potential issues. The acceptable range of moisture content varies depending on the material. For instance, concrete typically has an acceptable moisture content of 4-12%, while wood typically ranges between 6-12%. It's important to note that these levels may vary slightly based on regional conditions and building codes. ### What is a Bad Moisture Reading? Moisture readings that exceed acceptable limits are considered "bad." Excessively moist building materials can compromise structural integrity, create favorable conditions for mold growth, deteriorate finishes, and affect indoor air quality. Identifying and addressing bad moisture readings is crucial for maintaining the health and safety of a building and its occupants.
