The Concrete Polishing Council (CPC), a specialty council of the American Society of Concrete Contractors (ASCC), St. Louis, recently published three Position Statements: “Slab Protection by Others,” “Slip Resistance of Polished Concrete,” and “Coordinating the Concrete and Polishing Contractors’ Subcontracts.” The three were published in the November 2017 issue of Concrete International, the magazine of the American Concrete Institute (ACI).
Position Statement #1 on slab protection asserts that post-placement and post-polishing slab protection are not the responsibility of the polishing contractor who is not onsite at those times.
Position Statement #2, slip resistance, explains that all results of extensive testing shows the dynamic coefficient of friction (DCOF) exceeding requirements, even at very high gloss levels.
Position Statement #3, coordinating subcontracts, contends that waiting until after the concrete slab is finished to purchase polished contractor services can result in increased costs and a limited choice of final surface appearances. Because polishing a floor uncovers the slab surface, coordinating this process with initial construction is critical in having a successful project.
The Position Statements were written by ASCC technical director Bruce Suprenant and reviewed by select CPC members. Click here to read the complete papers.
The CPC was formed to provide standards, education and a professional network for polishing contractors and others serving in the industry. The primary goals are to furnish training opportunities and certification programs for members and to share information on best practices with the design and construction community.
