Lafayette Epoxy Floors › Services › Slab Moisture Mitigation
Lafayette Epoxy Floors is the Lafayette starting point for slab moisture testing and mitigation ahead of a floor coating. Tell us the age of the slab, whether it has ever flooded and whether an earlier coating failed. Request a free quote and a local epoxy flooring installer will call you back.
Lafayette sits on low, flat ground with a high water table in many neighborhoods, and the region gets heavy rain from tropical systems and summer storms. Concrete is porous, so moisture in the soil below a slab moves upward as vapor. A coating that traps that vapor can blister, turn cloudy or lose its grip.
How slabs are tested
Common tests include a calcium chloride kit placed on the slab, in-slab relative humidity probes drilled into the concrete, and a simple plastic sheet taped down overnight to look for darkening. Installers pick the method that suits the job size and the product they plan to use. Ask what test they use and what reading would change their plan.
Testing is most useful after grinding, when the surface is open.
Mitigation options
When readings are high, the usual fix is a moisture-tolerant epoxy primer or a dedicated vapor barrier coat applied before the decorative system. These products are thicker and slower to cure, so they add a step and some time. In some commercial cases, the answer is a different flooring choice altogether. Ask the installer which product they use and what moisture limit it is rated for.
Fixing drainage helps too. Gutters that dump at the slab edge and yards that slope toward the garage keep the soil under the concrete wet.
After a flood
Slabs that sat under floodwater can hold moisture for weeks or longer. Give the concrete time to dry, and test before any new coating goes down. If an old coating is lifting after a storm, see grinding and prep for removal, then plan the new system around the test results.
Frequently asked questions
My old epoxy is bubbling. Is it moisture?
It may be, though poor prep or contamination cause similar failures. An installer can test the slab and look at the underside of a lifted piece to judge.
Who does the work, and is the quote free?
Yes, the quote is free. Testing and coating are done by a local installer under an agreement you make with them; read how it works.
