Acceptable Moisture Levels
Moisture mapping is a non-destructive technique used to identify areas of moisture intrusion in building envelopes. Acceptable moisture levels in walls vary depending on the type of material used and the building’s location. However, as a general rule, moisture content in walls should not exceed:
* Wood: Less than 15%
* Gypsum board: Less than 10%
* Concrete: Less than 4%
How Much Moisture is OK in Walls?
The presence of moisture in walls is not always a cause for concern. Small amounts of moisture can be absorbed by the materials without causing damage. However, if moisture levels exceed the acceptable range, it can lead to:
* Rot and decay of organic materials
* Mold growth and associated health risks
* Structural damage
* Degraded indoor air quality
To prevent these issues, it is important to address moisture intrusions promptly. If you suspect that your walls may be experiencing moisture problems, contact a qualified moisture mapping professional for an assessment.
