Wood moisture content refers to the amount of water present in the wood relative to its dry weight. It significantly influences the material’s properties, including its strength, durability, and susceptibility to decay. Understanding wood moisture content is essential for effective moisture management and preventing wood damage.
Mold growth on wood is a common problem that can compromise the integrity of the wood and pose health risks. The critical moisture content at which mold growth becomes a concern is highly dependent on the type of wood, temperature, and humidity. Generally, mold growth can occur when:
* **Hardwoods:** Moisture content exceeds 20%
* **Softwoods:** Moisture content exceeds 18%
However, it’s important to note that even at lower moisture content, prolonged exposure to high humidity can create conditions conducive to mold growth.
Moisture mapping is a diagnostic technique used to identify areas of high moisture concentration in a building or wooden structure. By identifying these areas, the appropriate measures can be taken to address the underlying moisture issues and prevent mold growth.
Moisture mapping involves:

Moisture content plays a crucial role in the vulnerability of wood to mold growth. Moisture mapping provides a valuable tool for identifying and addressing moisture issues, preventing costly damage and protecting the health of occupants. Regular inspections and moisture mapping can significantly contribute to the proper maintenance and longevity of wooden structures.
