### What is Moisture Mapping?
Moisture mapping involves assessing the moisture content of building materials and structures to identify dampness or water damage. This process is essential for maintaining the structural integrity and indoor air quality of buildings.
### Acceptable Moisture Levels for Internal Walls
The ideal moisture content for internal walls varies based on factors such as the type of wall and the climate. However, general guidelines recommend the following moisture levels:
– **< 16%:** Dry and acceptable - **16-25%:** Slightly damp, may require monitoring - **> 25%:** Significantly damp, indicating potential moisture damage
Sustained moisture levels above these thresholds can lead to mold growth, structural weakening, and other health hazards.
### What Should Moisture Readings Be for Internal Walls?
Moisture readings for internal walls are typically taken using a moisture meter. The specific target moisture level may vary depending on the wall material and location within the building. However, the following ranges are generally acceptable:
– **Plasterboard and Stud Walls:** < 12% - **Solid Brick Walls:** < 6% - **Concrete Walls:** < 4% It is important to note that these are general guidelines. Building experts should be consulted to determine the appropriate moisture levels for specific walls and buildings.
