• FORTA-FERRO®

Joint-Free Topping Slab

Project Description:

The Sparkles Roller Rink in Marietta, Georgia, required a repair solution for their cracked and deteriorated roller-skating floor surface. Concrete contractor, Teddy Prince, of Atlanta offered a topping slab over waterproof membrane solution, using conventional steel reinforcement and saw-cuts on 15-foot centers, however, project owner Jeff Couey objected to the cut joints due to skating wheel traffic. Due to previous positive experience with the FORTA-FERRO® structural synthetic fiber, Prince suggested the three-dimensional fiber alternate as the best opportunity to approach a joint and crack-free surface on this very large 81 ft. x 167 ft. floor. FORTA-FERRO® 2-1/4" fiber was used at a dosage of 7.5 lbs./cu.yd. in this 4" thick topping, and offered no placement difficulties or surface blemishes in this laser-screed and machine troweled finish. The fiber was used in a 4,000 psi design mix and was placed at a 6" slump for this steel-free floor, which was wet-cured for three days. The FORTA-FERRO® reinforced floor achieved super-flat caliber results, and remains crack-free after five years in service. The Sparkles Roller Rink repair project also received the 2004 Award of Excellence in the Restoration Category by the Georgia Chapter of the American Concrete Institute.
