Moisture Mapping is a non-destructive technique employed to determine the moisture content of building materials, such as drywall, wood, and concrete. It involves using specialized equipment to measure the electrical resistance of the material, which is then correlated to moisture levels.
For most building materials, an acceptable moisture level typically ranges between 5% and 15%. Moisture levels below this range indicate a dry environment, while readings over 15% may suggest excessive moisture that can lead to problems such as mold, mildew, and structural damage.
A bad moisture reading refers to any measurement that exceeds the acceptable range. High moisture levels can occur due to various factors, including water leaks, plumbing issues, or poor ventilation. These conditions can promote microbial growth and deterioration of building materials, compromising indoor air quality and structural integrity.
