Controlling Quality Key to Performance of Concrete Floors
New PCA Publication Provides Specific Guidance and Direction

SKOKIE, Ill.— Unwanted moisture in concrete floors annually causes millions of dollars in damage to buildings in the United States.  Problems from excessive moisture can include deterioration, trip-and-fall hazards and microbial growth, which can lead to reduced indoor air quality, staining, and deterioration of building finishes. 

For a floor to function successfully, specifiers, builders, owners, and finish/flooring installers each must understand the factors for floor performance, especially moisture.  This is critical to preventing this damage and ensuring concrete floors and flooring systems that provide excellent service for many years.

The second edition of Concrete Floors and Moisture from the Portland Cement Association (PCA) discusses the sources of moisture, proper drying of concrete, methods of measuring moisture, construction practices, specifications, and responsibilities for successful floor projects.   This edition includes discussion of terrazzo issues and a detailed discussion of issues with ASTM F1869 moisture emission testing. 

Additionally, the publication updates references on drying times of lightweight concrete, and the sources of supplies and standards.
