Slab & Substrate
Can you install hardwood floors on a concrete slab in Florida?
Yes — in Florida, hardwood is installed on a concrete slab by using engineered hardwood glued down over a tested, moisture-controlled slab, not solid ¾" wood.
Most Gulf Coast homes are built slab-on-grade, and concrete is a constant source of moisture. Engineered hardwood has a dimensionally stable core that tolerates that environment; solid ¾" hardwood does not and should not be glued directly to a slab here.
The correct process is: test the slab’s internal relative humidity (ASTM F2170), flatten it, apply a moisture-control adhesive or membrane matched to the reading, and full-spread glue the engineered flooring. Done that way, the finished floor is indistinguishable from solid hardwood and far more reliable in this climate.

Do you need to moisture-test a concrete slab before installing wood floors?
Yes — a concrete slab must be moisture-tested before installing wood flooring, and the industry standard is the in-situ relative-humidity probe test, ASTM F2170.

Yes — a moisture-control layer or vapor retarder is needed between a Florida concrete slab and a glued-down wood floor, sized to the slab’s measured moisture level.
