Most floorcovering failures result from design mistakes, lack of groundwater barriers, and placement of the material before concrete has dried to safe levels. Therefore, all members of the project team must collaborate at every stage, such as the design, placement, curing, and relative humidity (RH) testing of the concrete.

Moisture rising from concrete slabs can come from numerous sources, including concrete, drainage, burst pipes, condensation, aggregate above a membrane, and the ground itself. Although the problem appears in different forms, the outcome is always the same—the flooring will fail.

Anyone involved with concrete finishing and protection—either through design, supply, or installation—is likely to have been affected by blistering and other moisture-related failures on floor finishes. A multi-million-dollar problem in North America, there are numerous reasons for such failures. However, a conversation being had more frequently today surrounds the relationship between alkali-silica reaction (ASR) and near-surface alkali reaction (NSAR) and finishing failures.
