What is Relative Humidity Testing?
Relative humidity testing is a the most reliable method of quantifying the water vapour in a concrete substrate. This test method involves drilling holes in concrete into which a relative humidity probe is placed to provide a reading from within the substrate. Manufacturers of coatings and finishes generally require moisture testing to be performed before installation on concrete.
Excessive moisture in floor slabs after floor covering has been installed can cause floor covering system failures such as debonding, peaking and deterioration of finish flooring and coatings and microbial growth.
Waterproofing Integrity technicians use calibrated TRAMEX CMEX-II Expert Moisture Meter to conduct insitu probe testing in accordance with ASTM F2170 – 19(2017) – Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using insitu Probes.


Why choose this test?
Our technicians use calibrated digital RH probes to determine precise internal humidity levels throughout the slab. We interpret results in line with AS 1884 and manufacturer limits, helping you decide whether conditions are safe for installation or if further drying time is required. This protects your investment, ensures warranty compliance, and prevents premature failure.
