**Moisture Mapping** Moisture Mapping is a thorough investigation to identify and locate areas where moisture has intruded a structure or property. This process is essential for preventing and mitigating water damage, ensuring the health and safety of occupants, and maintaining the integrity of the building or property. ### Detection Methods for Moisture Mapping **1. Visual Inspection:** - This initial step involves examining the structure for visible signs of moisture damage, such as stains, mold growth, or peeling paint. **2. Moisture Meters:** - Moisture meters are non-invasive devices that measure the moisture content within materials, providing quantitative data on the presence of moisture. **3. Infrared Thermography:** - Infrared cameras detect temperature differences, which can indicate areas where moisture has accumulated. **4. Electrical Impedance Tomography (EIT):** - EIT uses electrical currents to create a map of the structure's moisture content. ### How to Check for Moisture Under Your House 1. **Inspect Crawl Spaces:** Look for dampness, mold, or water stains on the walls, floors, and beams. 2. **Check Foundation Walls:** Use a flashlight to examine the foundation walls for cracks or holes that could allow moisture to seep in. 3. **Examine Pipes and Drains:** Inspect pipes and drains for leaks or blockage. If water is not draining properly, it can accumulate under the house. 4. **Use a Moisture Meter:** Place the moisture meter probe into the soil surrounding your foundation. High moisture readings indicate potential moisture intrusion. 5. **Hire a Professional:** If you suspect significant moisture issues under your house, it's advisable to consult a moisture mapping professional for a comprehensive assessment and mitigation plan.
