David Mitchell owns Bunyan Industries, a Salt Lake City-based manufacturer of roller screeds. In this article from Public Works sister publication Concrete Construction, he explains why superabsorbent polymer (SAP) wasn't used on a pervious concrete slab embellished with the American Concrete Institute's new logo.
