Summary
In-situ relative humidity (RH) testing is a method used to evaluate internal moisture conditions within a concrete slab prior to flooring installation. The test measures the relative humidity within drilled holes at a specified depth to assess moisture equilibrium inside the concrete matrix. RH testing reflects internal slab moisture conditions at the time and location of testing. Test results are compared to
