Moisture Mapping is a process that is used to identify areas of moisture in a building. This can be done using a variety of methods, including infrared cameras, moisture meters, and psychrometers. Once the areas of moisture have been identified, they can be addressed and repaired to prevent further damage to the building.
The acceptable moisture level in walls varies depending on the climate and the type of wall construction. However, in general, the moisture content of walls should be less than 15%. If the moisture content is higher than this, it can lead to problems such as mold growth, rot, and structural damage.
