It is now widely understood that moisture emissions from concrete substrates are a major concern when applying impermeable coatings, linings or floorings. There are many ways which the concrete can be tested to detect moisture in, or emitting from it. However, there remains to be many various theories and opinions regarding test methods and interrupting the results.
This presentation is based on a practical study that was performed in an effort to exemplify the various field conditions and obstacles encountered in performing these test in typical field conditions. It looks at all the accepted standard methods and examines both the similarities and differences. How they are performed, what they are designed to report, common problems, and most importantly how their results can be skewed or misinterpreted.
