About
A moisture membrane is a vapor-reduction layer installed directly on the concrete before the flooring system. We use PUR-VRM-EXT, a 100% solids, two-component epoxy that meets ASTM F3010 requirements for vapor permeance when applied at 18 mils. It forms a seamless, impermeable barrier that controls moisture vapor emission from new and existing slabs — the most common cause of blistering and delamination in South Florida, where high groundwater and humidity keep slabs damp. It contains no solvents and can be installed in occupied facilities.
Right Fit
Best For
Mechanical Room
Drying / Curing Rooms
Greenhouse & Indoor Grow Facilities
Cleanrooms
Laboratory Floors
Not For
- A finished floor on its own. It's a protective under-layer and always gets a coating system on top.
- Unprepared concrete. Cracks, oils and old coatings must be ground and repaired first, or it won't bond.
