Moisture mapping is the process of measuring and recording the moisture content of a building or other structure. This information can be used to identify areas of moisture intrusion, assess the severity of the problem, and develop a plan for remediation.
Acceptable moisture levels in buildings vary depending on the climate, the type of construction, and the intended use of the space. However, as a general rule, the relative humidity (RH) should not exceed 50% and the moisture content of building materials should not exceed 15%. Higher levels of moisture can lead to mold growth, structural damage, and other health and safety concerns.
A bad moisture reading is any reading that exceeds the acceptable moisture levels for the specific building or structure. This could indicate a problem with the building envelope, such as a leak or a lack of ventilation, or it could be a sign of a more serious problem, such as a flood or a sewer backup.
If you get a bad moisture reading, it is important to contact a qualified professional to investigate the cause of the problem and recommend a course of action.
