Moisture penetration through concrete slabs can cause severe problems for subsequent resilient flooring systems. High concentrations of moisture and alkalinity (levels determined through testing) can lead to the deterioration of flooring adhesives and delaminating of coatings. To avoid this problem, the concrete slab should be primed with a material that will tightly bond to the concrete. Resilient flooring (i.e. VCT, sheet vinyl, etc) may require a cementitious underlayment to act as a blotter layer for the adhesive, or to level and smoothen the finish prior to installing the adhesive and final flooring system. Problems in concrete slabs can cost owners hundreds of thousands of dollars if not identified prior to floor installation. We install systems designed to reduce the Moisture Vapor Emission Rate (MVER) in concrete of up to 25 lbs per 1000 square feet, per 24 hours to less than 3 lbs per square foot.
