When Rockwell Automation Corp., Milwaukee, Wis., set out to build a new conveyor-drive manufacturing facility in Clio, S.C., one of the top demands was a high-performance floor slab with excellent abrasion resistance and minimal cracking and curling. Nothing less would do, since this 150,000-square-foot floor would serve as the work platform for all the facility's manufacturing operations.

Selected to tackle the job was Ace/Avant Concrete Construction Co. Inc., a contractor with a history of success installing high-performance floors of this type. Continuous planning, from the bidding stage through the final curing and sealing of the floor, helped the project team achieve its goal: a high-performance floor with a very flat, level surface. The floor tolerance was FF 35/FL 25, and the floor measured FF 49.7/ FL 41.3.
