Wood moisture content refers to the amount of water present within the wood’s structure. It is expressed as a percentage of the wood’s oven-dry weight. Measuring wood moisture content is crucial for various reasons, including:
The ideal moisture content for treating wood varies depending on the treatment method and the species of wood. However, general guidelines include:
Maintaining the recommended moisture content is essential to ensure the effectiveness of wood treatments. Treating wood with a moisture content outside the recommended range can result in reduced treatment penetration, increased risk of premature failure, or even the reversal of treatment effects.
Moisture mapping is a technique used to identify areas of varying moisture content within a wooden structure. This information can help determine the most appropriate treatment methods and target areas for inspection or repair. Moisture mapping is typically conducted using a moisture meter, a specialized instrument that measures electrical resistance to estimate wood moisture content. By identifying areas of high moisture content, moisture mapping can help optimize treatment strategies and ensure the longevity of wooden structures.
