Moisture mapping is a technique that evaluates the moisture content and distribution within a wooden structure. Understanding wood moisture content is crucial for ensuring its durability and structural integrity.

What is Moisture Content in Wood?

Wood moisture content (MC) refers to the amount of moisture present in wood relative to its mass. It is typically expressed as a percentage and signifies the balance between water absorbed by the wood fibers and the water released to the surrounding environment.

The MC of wood influences its various properties, including:

• Dimensional stability: Moisture absorption causes wood cells to expand, leading to swelling and warping. Conversely, moisture loss results in shrinkage.
• Decay susceptibility: High MC increases the risk of wood decay caused by fungi and insects.
• Insulative value: Moist wood has poor thermal insulation properties, reducing energy efficiency.

Understanding and controlling wood moisture content is essential for preventing structural problems, ensuring longevity, and maintaining the desired performance of wooden structures. Moisture mapping provides valuable insights into wood moisture conditions, enabling timely and effective remedial actions.
