Moisture vapor transmission lifting coatings from below
Why it happens here
Richmond sits on low, wet ground, and Brighouse slabs can push water vapor up through concrete for years. Below-grade storage rooms and older parkades are the worst offenders. A slab that reads dry on the surface can still be over tolerance.
Our approach
We take moisture meter readings at multiple points before quoting and grind the slab to open the profile. Where readings run high, we specify a vapor-blocking primer or a moisture-tolerant system. It costs a little more upfront and it is the reason our coatings stay bonded.
