Moisture Mapping is a non-destructive testing method used to identify moisture issues within a property. By utilizing specialized equipment, trained professionals can accurately measure moisture levels in various building materials, including internal walls.
Acceptable Moisture Levels
The acceptable moisture levels for internal walls vary depending on the material and its condition. However, general guidelines can be provided to ensure proper indoor air quality and prevent structural damage:
- Drywall: Less than 15% moisture content (MC)
- Plaster: Less than 5% MC
- Brick: Less than 4% MC
- Concrete: Less than 2% MC
It’s important to note that these values represent ideal conditions and may vary slightly in practice. Moisture levels should be consistently monitored to identify any changes or potential concerns.
What Should Moisture Readings Be for Internal Walls?
Moisture readings for internal walls should be below the acceptable levels mentioned above. High moisture levels can indicate water damage, mold growth, or other underlying issues that require immediate attention. Typical acceptable moisture readings for internal walls are as follows:
| Material | Acceptable Moisture Range |
|---|---|
| Drywall | 0-10% |
| Plaster | 0-3% |
| Brick | 0-2% |
| Concrete | 0-1% |
If moisture readings exceed these ranges, it is highly recommended to seek professional assistance to determine the source of the moisture and develop a plan to address it promptly.
