Moisture mapping is a valuable technique for identifying and addressing moisture problems in buildings. It involves measuring moisture content in various building materials, including wood, to assess the risk of damage or mold growth.
Wood moisture content refers to the amount of water held within the wood’s structure. WMC is expressed as a percentage of the wood’s weight when it is oven-dry. The ideal WMC for wood in most construction applications is between 6% and 12%.
Mold spores are present all around us, but they require specific conditions to grow, including a suitable food source and moisture. Wood provides an excellent food source for mold, and when the WMC exceeds 20%, the likelihood of mold growth increases significantly. At WMC levels above 28%, mold growth is almost inevitable.
Therefore, it is crucial to maintain WMC below 20% to prevent mold infestation. Regular moisture mapping can help detect areas where WMC is elevated, allowing for timely intervention to address moisture issues and prevent mold growth.
Moisture Mapping Benefits:
– Identifies moisture problems early
– Facilitates targeted repairs
– Prevents mold growth and associated health risks
– Reduces the risk of structural damage
