Can a floor look dry and still have moisture vapor?

Yes. RFCI notes that moisture vapor can pass through a slab even when the surface appears dry. Product-required testing is the decision input.

Is one moisture reading enough?

Not necessarily. Test method, number and location of tests, occupied conditions, slab area, and manufacturer requirements matter.

Does floating LVP eliminate slab moisture risk?

No. Products and underlayments have different limits, and active water or excessive moisture can affect the broader assembly and indoor conditions.

Concrete Slab Moisture Signs | Austin Floors

Review possible slab moisture signs under resilient flooring, why visual evidence is not a test result, and when an Austin project needs field testing.

Odor, discoloration, adhesive change, open joints, curling, deposits, or repeated floor movement may justify moisture investigation, but visual signs do not measure slab conditions. Product-specific tests and limits are required. Address active leaks immediately. Use qualified water, environmental, plumbing, or structural professionals when the condition extends beyond flooring scope.
