Moisture Mapping is a technique used in the construction industry to measure and analyze moisture levels in building materials, such as wood. It provides valuable insights into the moisture content of wood and other porous materials, helping professionals make informed decisions regarding construction and renovation projects.
The moisture content of wood refers to the amount of water present within the wood fibers. It is expressed as a percentage of the weight of the wood when oven-dry. The ideal moisture content for wood used in construction typically ranges between 6% and 12%.
Surprisingly, wood can contain over 100% moisture content. This condition is known as “above fiber saturation point” (FSP) and occurs when the wood has absorbed as much moisture as it can. At this point, the wood is fully saturated and any additional moisture will not be absorbed but will instead occupy the spaces between the wood fibers.
When wood is above FSP, it becomes more susceptible to rot and decay as the excess moisture provides an ideal environment for microorganisms to thrive. It also becomes less structurally sound, which can pose safety concerns. Therefore, it is crucial to control moisture levels in wood to prevent it from reaching this critical point.
