Concrete Moisture Testing – What Restorers Need to Know
In Australia, AS 1884:2021 (the standard for resilient floor coverings) mandates the use of the ASTM F2170 in-situ relative humidity (RH) test to assess moisture in concrete subfloors before installing resilient flooring.
For restorers, this is more than a flooring installer’s requirement—it’s a critical verification step in any water damage or concrete drying job. You must test the floor to confirm it has reached the required moisture condition before handover. Using the ASTM F2170 method ensures accurate, standard-compliant results that protect flooring warranties, reduce the risk of failure, and provide defensible documentation for clients and insurers.
At BULCS, we provide hands-on training in carrying out these tests, including correct procedures, compliance requirements, and equipment use. Recommended meters include the Protimeter MMS3 with in-situ hygrometer and the Tramex in-situ meter—both reliable tools for meeting AS 1884 and ASTM F2170 requirements.
In short: if you’re drying a slab for flooring installation, make sure the RH test is done—and done to the standard.
