Moisture mapping is an essential step in the identification and remediation of moisture issues in commercial buildings. It involves using various methods to locate moisture sources, determine the extent of the damage, and guide repair efforts. Accurate moisture mapping helps prevent costly repairs and ensures the health and safety of occupants.
*
Infrared thermography is a non-invasive method that uses thermal imaging to identify temperature differences in building surfaces. Areas with higher moisture content typically have cooler temperatures, allowing for easy detection.
*
Electrical resistance tomography (ERT) involves injecting electrical currents into the building structure and measuring the resistance at different points. Moisture presence disrupts the electrical field, leading to higher resistance values.
*
Capacitive imaging uses sensors to measure changes in capacitance caused by moisture in building materials. The higher the moisture content, the lower the capacitance.
*
Moisture meters are handheld devices that measure moisture content based on electrical conductivity. Invasive and non-invasive moisture meters are available.
1.
Remove any wall coverings, such as paint or wallpaper.
2.
Select a moisture mapping method appropriate for the wall type and moisture level suspected.
3.
Use the selected moisture mapping equipment to scan the wall surface and collect data on moisture content and distribution.
4.
Interpret the moisture mapping data to identify moisture sources, determine the extent of damage, and plan remediation measures.
5.
Prepare a comprehensive moisture mapping report that outlines the test results, detected moisture areas, and recommendations for remediation.
By utilizing appropriate moisture mapping methods and conducting thorough moisture tests on walls, building professionals can effectively identify and address moisture problems, ensuring the integrity and safety of commercial buildings.
