Why Relative Humidity Testing?

The flooring industry has come to understand the importance of testing the concrete slab’s moisture condition when preparing for a flooring installation. 

Testing is really quite easy. But which moisture test should you use? Several different methods of concrete moisture testing are available. How can you be sure that you’re choosing a reliable method of moisture measurement?

Is one test method any better than another?

The simple answer is yes! The scientific evidence consistently points to a single method of testing as the most accurate and reliable. This is why people in the flooring industry today are moving more and more to the use of in situ relative humidity (RH) testing.

RH testing, standardized as ASTM F2170, involves placing in situ RH probes at specific depths in the slab. After allowing the RH probes to equilibrate, measurements of RH are taken to assess the overall moisture condition of the slab.

Decades of research in Europe and the United States clearly show that RH testing is the most reliable method for accurately determining the moisture condition of concrete floor slabs.

Learn what the experts discovered and why you should not depend on other test methods, including the anhydrous calcium chloride test. Check out these great learning resources, all available for free.
