Moisture Vapor Barrier
In waterfront South Florida, on-grade slabs push water vapor upward — and that vapor blisters and delaminates floors from below. A moisture vapor barrier is a 100%-solids epoxy applied first that blocks emissions up to ~99% RH, so the floor above it lasts.
What you get
Blocks osmotic blistering and delamination
Rated for slabs up to ~99% relative humidity
Essential on waterfront and on-grade concrete
Added only when a moisture test calls for it
Ideal for: Waterfront homes, ground-floor slabs and any high-moisture concrete.
