Earlier this month, ASTM International published its revised ASTM F2170, Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes. The updated standard reduces the mandatory wait period before obtaining official, documentable results from an in-situ relative humidity (RH) moisture test performed in concrete floor slabs from 72 to 24 hours.
Moisture presence in concrete slabs can cause problems for all types of floors, including carpeting, wood, stone, poured polymeric, and resilient finish. Too much moisture can cause floorcoverings to cup, buckle, blister, and discolor, and these problems can occur days, months, or years after installation.
