Introduction
Moisture Mapping is a critical process in the construction and maintenance of buildings. It involves measuring the moisture content of wood and other building materials to identify areas of excessive moisture that could lead to structural damage or mold growth.
Wood Moisture Content
Wood moisture content is the amount of water present in the wood fibers. It is expressed as a percentage of the oven-dry weight of the wood.
- Green wood has a moisture content of over 20%.
- Seasoned wood has a moisture content of 12-15%.
- Dry wood has a moisture content of less than 12%.
At What Moisture Content Does Mold Grow on Wood?
Mold typically begins to grow on wood when the moisture content exceeds 16-20%. High moisture content provides a suitable environment for mold spores to germinate and thrive, leading to structural damage and health concerns.
Conclusion
Moisture Mapping is an essential tool for identifying moisture problems in buildings. By accurately measuring the moisture content of wood and other materials, professionals can determine the cause of moisture build-up and take appropriate action to prevent structural damage and mold growth.
