Moisture Mapping is a crucial technique for identifying and managing moisture issues within buildings. Establishing acceptable moisture levels for internal walls is essential to maintain structural integrity, prevent mold growth, and ensure a healthy indoor environment.

### Acceptable Moisture Levels for Internal Walls

The acceptable moisture content for internal walls varies depending on several factors, including the material used for construction. Generally, the desired moisture content for drywall, plaster, and other wall finishes is below 15%.

### What Should Moisture Readings Be for Internal Walls?

When conducting Moisture Mapping, readings are taken using a moisture meter. The readings are typically expressed as a percentage of moisture content. For internal walls, the following moisture readings are considered acceptable:

* **Below 10%:** Indicates that the wall is dry and moisture levels are within normal range.
* **10% – 15%:** Requires monitoring, as moisture levels are approaching the acceptable threshold.
* **Above 15%:** Indicates excessive moisture and requires further investigation and corrective action.

It’s important to note that these readings are guidelines, and specific moisture levels may vary depending on the construction materials, climate, and other environmental factors.
