Moisture mapping is a process of identifying and locating areas of moisture intrusion in a building. It allows for the detection of moisture problems, such as leaks, condensation, and flooding, which can lead to structural damage and health risks.
The acceptable moisture levels for internal walls vary depending on the materials used, environmental conditions, and building codes. In general, the moisture content of internal walls should be below 16%. Higher moisture levels can indicate a moisture problem that requires further investigation and remediation.
Moisture readings for internal walls can be obtained using a moisture meter. The following table provides general guidelines for acceptable moisture levels, based on the type of wall construction:
| Wall Construction | Acceptable Moisture Level | |---|---| | Drywall | Less than 13% | | Plasterboard | Less than 10% | | Brickwork | Less than 9% | | Concrete | Less than 6% |It's important to note that these values are general guidelines and may vary depending on specific factors, such as the age of the building, climate, and ventilation conditions. If moisture readings exceed these levels, it is recommended to consult with a qualified professional for further assessment and remediation.
