Moisture mapping is the process of measuring the moisture content of a material, typically wood or concrete, using a moisture meter. This information can be used to identify areas of excessive moisture that may indicate a problem, such as a leak or water damage.
### What is an Acceptable Damp Reading?
Acceptable moisture levels vary depending on the material being tested and the environment in which it is located. However, in general, the following moisture readings are considered acceptable:
– **Wood:** 6-12% moisture content (MC)
– **Concrete:** Less than 4% MC
Moisture readings above these levels may indicate a problem that needs to be addressed. For example, high moisture content in wood can lead to rot and decay, while high moisture content in concrete can lead to cracking and spalling.
