Moisture Mapping Acceptable Moisture Levels

What is Moisture Mapping?

Moisture mapping is a detailed assessment of the moisture content of a structure. It provides accurate readings of moisture levels in various areas of the building, allowing for targeted and effective moisture remediation.

Acceptable Moisture Levels

The acceptable range of moisture levels varies depending on the material and location within the building. Generally, the following guidelines apply:

  • Wood: Less than 15% moisture content
  • Concrete: Less than 4% moisture content
  • Drywall: Less than 5% moisture content
  • Insulation: Less than 5% moisture content

What is an Acceptable Damp Reading?

A damp reading is a measure of the electrical resistance of a material to the passage of current. It is commonly used to assess the moisture content of wood and masonry. The higher the damp reading, the higher the moisture content.

Acceptable damp readings vary depending on the type of material and environmental conditions. However, as a general rule of thumb, the following ranges are considered acceptable:

  • Wood: 10 to 25 units
  • Masonry: 20 to 40 units

It’s essential to consult with a qualified moisture mapping professional for accurate readings and recommendations based on specific circumstances.
