Moisture presence in concrete slabs can cause problems for all types of floors, including carpeting, wood, stone, poured polymeric, and resilient finish. Too much moisture can cause floorcoverings to cup, buckle, blister, and discolor, and these problems can occur days, months, or years after installation. In other words, excess moisture adversely affects the assembly’s short- and long-term viability.
One of the biggest mistakes a designer can make when specifying polished concrete slabs is to state, “Concrete for polished concrete, including formwork, reinforcement, concrete materials, mixture design, placement procedures, initial finishing, and curing is specified in Section 03 30 00 Cast-in-Place Concrete.”
