When MVB is Required
- Moisture testing shows elevated vapor transmission
- Previous coating failures on the slab
- Signs of efflorescence (white powder)
- Metallic epoxy installations
- Slabs poured on grade without vapor barriers
Why We Include It
We include MVB as standard on metallic epoxy systems because moisture-related failures are too common and too costly to risk.
For other systems, we test every floor and recommend MVB when moisture levels exceed safe thresholds—protecting your investment from the ground up.
Grey-Tinted MVB from XPS
We use XPS grey-tinted moisture vapor barrier for enhanced visibility during application and consistent coverage verification.
This professional-grade MVB is rated for moisture vapor transmission rates up to 25 lbs/1000 sq ft/24 hrs.
The Hidden Problem
Moisture vapor naturally rises through concrete slabs. In Texas, our clay-heavy soils and variable weather create high moisture vapor transmission rates that can destroy epoxy coatings from beneath—even on slabs that appear completely dry.
Signs of Moisture Problems:
- Bubbling or blistering in existing coatings
- White powder (efflorescence) on concrete surface
- Peeling or delaminating floor coatings
- Musty smell in garage or basement
- Previous coating failures
Did You Know?
A 1,000 sq ft concrete slab can transmit up to 18 gallons of water vapor per day through the surface—enough to cause catastrophic coating failure.
That's why we test every floor before installation and include MVB protection when needed—at no surprise cost to you.
