Moisture Mapping Understanding Acceptable Moisture Levels

Acceptable Moisture Levels

Moisture mapping is a critical tool for assessing the moisture levels within a building envelope. Establishing acceptable moisture levels helps ensure structural integrity and prevent moisture-related issues such as mold growth and wood decay.

What is an Acceptable Damp Reading?

Moisture content is typically expressed as a percentage of the material's dry weight. Acceptable moisture levels vary depending on the material and its intended use. However, a general guideline for acceptable damp readings is as follows:

  • Wood: Below 18%
  • Concrete: Below 4%
  • Sheetrock: Below 6%
  • li>Insulation: Below 15%

Materials with moisture levels above these thresholds are considered damp and may require drying or remediation to prevent further damage.
