Abstract: Recent changes in the installation and composition of floor finishes for concrete floor slabs have made these materials more susceptible to moisture- and alkalinity-related deterioration. This article reviews the sources of moisture in concrete floor assemblies and the current industry tests for determining slab moisture levels. A discussion on establishing a testing protocol, interpreting test results, and understanding test limitations is included, along with recommendations for minimizing the chances for flooring failures, mitigating existing high concrete moisture levels, and selecting appropriate finishes.
