Moisture Under Flooring
Slabs without adequate vapor barriers can push moisture up through the concrete. A standard coating fails; a moisture-mitigation system solves it. Every slab is different, so recommendations depend on an on-site evaluation — we do not diagnose specific floors from photos alone.
Common causes
- Below-grade slabs
- Slabs on poor vapor barriers
- Repeat coating failures
How we approach it
- Moisture testing before quoting
- Vapor-block primer systems
- Compatible finish coats over the mitigation layer
Preparation
- On-site evaluation of the concrete and any existing coating
- Moisture and adhesion testing where warranted
- Full mechanical preparation before any new material is installed
- Compatible repair materials for cracks, spalls, and pits
Frequently asked
How much extra does mitigation add?
It varies with the slab and system. We share numbers after moisture testing.
