Moisture mapping involves identifying and evaluating the presence and distribution of moisture within building structures. This process is crucial for detecting the potential for water damage, assessing the severity of existing damage, and implementing appropriate mitigation strategies.

## Moisture Mapping Detection Methods

### How to detect dampness in a wall?

**Visual inspection:**
* Check for visible signs of dampness, such as discolored patches, efflorescence, or mold growth.

**Moisture meters:**
* Use moisture meters to measure the moisture content of the wall in different locations.
* Expected moisture levels vary depending on the type of wall material and environment.

**Infrared camera:**
* Take infrared images to detect temperature differences that can indicate moisture presence.
* Warm areas indicate higher moisture content.

**Relative humidity sensors:**
* Place environmental sensors within the wall cavities to monitor relative humidity levels.
* Elevated humidity levels can be a sign of moisture buildup.

**Probing:**
* Drill or cut small holes into the wall to insert probes that measure moisture content.
* This method provides more precise data than non-invasive techniques.
