Moisture mapping is a non-destructive method for assessing the moisture content of building materials. It involves using a moisture meter to measure the electrical resistance of a material, which is inversely proportional to its moisture content. Moisture mapping can be used to identify areas of high moisture that may be indicative of water damage, leaks, or other issues.
Acceptable Moisture Levels for Internal Walls
The acceptable moisture level for internal walls is typically between 5% and 15%. Higher moisture levels may indicate a problem, such as a leak or water damage.
Moisture readings for internal walls should be taken at several locations, including:
- Near the floor
- Near the ceiling
- In the center of the wall
If the moisture readings are consistently above 15%, it is advisable to contact a qualified professional to investigate the cause of the high moisture levels.
