The measurement of moisture in building fabrics has been of interest for many years due to potentially devastating consequences of moisture problems within buildings. A range of potential techniques are available with which to measure the moisture content of building fabrics in situ and this paper focuses on two techniques which offer the potential for some significant advantages over approaches: (1) thermal dual-probe and (2) time domain reflectometry. The two approaches have been tested against measurements of moisture content using a laboratory-based X-ray measurement facility. As a result of the work that has been undertaken, the authors are very confident that the two measurement techniques are indeed applicable to typical building fabrics.
- thermal dual-probe
- time domain reflectometry
