### Moisture Mapping and Detection Methods Moisture mapping involves identifying moisture levels within a structure using specialized equipment and techniques. This mapping assists in detecting water damage, locating leaks, and assessing building envelope performance. ### How Does Moisture Mapping Work? Moisture mapping utilizes various methods, including: * **Infrared thermographic scanning:** Measures temperature variations to detect wet areas. * **Capacitance sensors:** Measure moisture content in building materials, such as drywall and wood. * **Microwave detection:** Penetrates materials to detect trapped moisture. * **Electrical impedance tomography (EIT):** Creates 3D images of moisture distribution within walls. ### Benefits of Moisture Mapping * **Accurate moisture detection:** Precisely identifies moisture levels in concealed areas. * **Early detection:** Detects water damage before it becomes severe. * **Leak location:** pinpoints the source of leaks within the building envelope. * **Building envelope assessment:** Evaluates the performance of insulation, vapor barriers, and other envelope components. * **Moisture management:** Provides data for managing moisture levels, preventing future damage.
