North American commercial property owners spend an estimated $2.4 billion dollars on remediation of structures and floor coverings as a result of moisture-related flooring failures yearly. An additional $2.2 billion dollars is spent on topical moisture treatments, of varying effectiveness, in an effort to address moisture issues prior to the first flooring ever being installed. Moisture vapor emission (MVE) has become more of an issue with fast track construction schedules, changes in adhesives, and sea-level rise over the past decade. Excessive MVE can be caused by lack of cure time under controlled conditions, curing compound, and improper water to cement ratios creating an excessive “water of convenience” used during the placement of a new slab. It can be caused in existing or renovated concrete as well due to lack of vapor retarders, improper or damaged vapor retarders, high ground water, irrigation, poor drainage and high water to cement ratio pours creating interconnected pores.
There are mechanically bonded and roll out sheet options to remediate MVE as well as finishes that are not sensitive to moisture vapor emissions (some resinous systems, ceramic tile and polished concrete.) At Cherry Carpet & Flooring, we have spent many years on education to know how to test, inspect, and ultimately know the best course to remedy these issues.
