Invasive moisture test methods penetrate building materials to provide accurate readings of moisture levels within walls. These methods are typically used when non-invasive methods cannot provide conclusive results or when the presence of moisture is suspected in areas that cannot be accessed by non-invasive means.
An invasive moisture test involves drilling a small hole into the wall surface and inserting a moisture probe. The probe measures the electrical resistance of the material, which is affected by its moisture content. The higher the moisture content, the lower the resistance. The results are then compared to a moisture content scale to determine the severity of the moisture problem.
In addition to the traditional moisture probe method, other invasive moisture test methods include:
The choice of invasive moisture test method depends on factors such as the type of material, the accessibility of the area to be tested, and the desired level of accuracy. It is recommended to consult with a qualified moisture inspection professional to determine the most appropriate method for your specific needs.
