Concrete Moisture Testing in Knoxville, TN
Moisture moving through a slab is one of the most common causes of coating failure. Testing catches the problem before it becomes an installed problem.
When Testing Matters
Basements, on-grade slabs, first-floor commercial floors, and any slab with prior coating problems benefit from testing.
Methods
Calcium chloride vapor tests and relative humidity probes are the two standards. Each has trade-offs; product specs guide the choice.
Interpreting Results
Results are matched against the coating product's tolerance. When numbers exceed tolerance, a moisture-mitigating primer or a different system is considered.
Frequently Asked Questions
How is moisture measured?
Common methods include calcium chloride tests (moisture vapor emission rate) and in-situ relative humidity probes drilled into the slab. The method depends on the coating product's specification.
What if moisture is too high?
Options include a moisture-mitigating primer rated for the measured level, or deferring coating until the source is addressed. Coating over untreated high moisture is the wrong answer.
