Assessing and addressing moisture vapour problems in new and old concrete floors with and without a functioning vapour barrier

摘要

This paper analyses the cause of failures in resin, vinyl and other resilient floor finishes and build-ups attributed to vapour drive. First, it examines the constituents and formation of concrete and why it contains a high quantity of moisture (vapour) and the damage it can cause tothe floor build-up, finish and the concrete itself. Secondly, it outlines the analysis and diagnosis of the problem and thirdly, describes the preparation and prevention in line with current technical guidelines. It concludes that an appropriate system should be included in the design on newor problematic floors to prevent future failures.
