What Is Moisture Mapping?
Moisture mapping is a process used to determine the moisture content of a building’s structure. It is typically done using a moisture meter, which measures the electrical resistance of a material to estimate the moisture content. Moisture mapping can be used to identify areas of moisture intrusion, such as leaks or condensation, and to assess the extent of damage.
Acceptable Moisture Levels for Internal Walls
The acceptable moisture level for internal walls varies depending on the material of the wall. However, in general, the moisture content of internal walls should be less than 15%. Higher moisture levels can lead to mold growth and other problems.
What Should Moisture Readings Be for Internal Walls?
The moisture content of internal walls can be measured using a moisture meter. The ideal moisture content for internal walls is between 5% and 12%. Readings above 15% indicate excessive moisture and may require further investigation.
Signs of Excessive Moisture in Internal Walls
- Visible mold growth
- Musty or stale odor
- Discoloration or staining of the wall surface
- Warping or buckling of the wall material
- High readings on a moisture meter
Causes of Excessive Moisture in Internal Walls
- Leaks from plumbing or roofing
- Condensation due to high humidity
- Ground moisture seeping through the foundation
- Poor ventilation
Remediation of Excessive Moisture in Internal Walls
If excessive moisture is detected in internal walls, it is important to identify the source of the moisture and take steps to address it. This may involve repairing leaks, improving ventilation, or installing a dehumidifier.
