Moisture Mapping: A Comprehensive Guide

Moisture Mapping is an essential technique used to assess the moisture content within building materials, such as wood. It provides valuable insights into the distribution of moisture and helps identify areas of concern.

Wood Moisture Content

Wood is a hygroscopic material that absorbs and releases moisture from the surrounding environment. The moisture content of wood is expressed as a percentage of the oven-dry weight of the wood. Different species of wood have varying moisture content levels, depending on their density and cellular structure.

Can Wood Contain Over 100% Moisture Content?

Yes, it is possible for wood to contain over 100% moisture content. This occurs when the wood is saturated with water, beyond its fiber saturation point. At this point, the wood’s cellular structure is filled with water, and additional water is present in the free spaces between the cells.

However, it’s important to note that exceeding the fiber saturation point can compromise the stability and durability of wood. It can lead to warping, swelling, and decay. Therefore, maintaining appropriate moisture levels is crucial for ensuring the longevity of wood structures.
