Destructive Moisture Evaluation

Destructive moisture evaluations are invasive procedures that involve opening up building materials to directly measure moisture content. Core sampling is a type of destructive evaluation that measures moisture content at different depths within a material.

Are Pinless Moisture Meters Accurate?

Pinless moisture meters are non-invasive tools that measure moisture content without damaging building materials. While they are generally less accurate than destructive moisture evaluations, they can be useful for quickly screening large areas for potential moisture problems.

  • Pinless moisture meters measure moisture content by sending electromagnetic waves into the material.
  • The speed at which these waves travel through the material is affected by the moisture content.
  • Pinless moisture meters can be used to measure moisture content in a variety of materials, including wood, drywall, and concrete.

It is important to note that pinless moisture meters are not always accurate, especially in materials with high moisture content or in very dry materials. If you suspect that a material may have a moisture problem, it is always best to confirm with a destructive moisture evaluation.
