Moisture Mapping What Are Acceptable Moisture Levels

Moisture Mapping

Moisture mapping is a process of measuring the moisture content of a building's structure. This process is typically done to identify areas of high moisture content that may be at risk for mold growth or other problems. Moisture mapping can be done using a variety of methods, including infrared scanning, moisture meters, and psychrometers.

Acceptable Moisture Levels

The acceptable moisture content of a building's structure will vary depending on the material being measured. However, in general, the following moisture levels are considered acceptable:

  • Wood: 6-12%
  • Concrete: 2-4%
  • Drywall: 0-5%
  • Insulation: 0-1%

What is an Acceptable Damp Reading?

A damp reading is a measurement of the moisture content of a surface. Damp readings are typically taken using a moisture meter. The acceptable damp reading for a surface will vary depending on the material being measured. However, in general, the following damp readings are considered acceptable:

  • Wood: 0-15%
  • Concrete: 0-25%
  • Drywall: 0-10%
  • Insulation: 0-5%

If the damp reading for a surface is higher than the acceptable level, it may be necessary to take steps to reduce the moisture content. This may involve repairing leaks, improving ventilation, or using a dehumidifier.
