Moisture Mapping Acceptable Moisture Levels for Internal Walls

Introduction

Moisture Mapping is a technique used to identify areas of excessive moisture within a property. When moisture levels exceed acceptable ranges, it can lead to a variety of problems, including mold growth, structural damage, and poor indoor air quality.

Acceptable Moisture Levels for Internal Walls

The acceptable moisture level for internal walls varies depending on the construction materials used. Generally speaking, the moisture content of internal walls should not exceed:

  • 5% for plasterboard walls
  • 8% for timber-framed walls
  • 12% for brick or concrete walls

What Should Moisture Readings Be for Internal Walls?

Moisture readings are typically taken using a moisture meter. If moisture readings exceed the acceptable levels listed above, it may indicate the presence of excessive moisture. Further investigation should be conducted to determine the source of the moisture and implement appropriate corrective measures.

Conclusion

Moisture Mapping is an essential tool for identifying areas of excessive moisture within a property. Understanding the acceptable moisture levels for internal walls and how to interpret moisture readings can help building professionals identify potential moisture issues and take appropriate action to prevent or mitigate damage.
