Abstract:
A playing surface assembly that defines at least a portion of a playing surface. The playing surface assembly has a backing, a plurality of reinforcement elements secured to and extending upwardly from the backing, and an infill material defining a top surface of the playing surface assembly. Each reinforcement element has a top end and a reveal distance corresponding to a vertical spacing between the top surface of the playing surface assembly and the top end of the reinforcement element. The reveal distance of each reinforcement element is less than 0.5 inches. In use, the reinforcement elements restrict lateral and vertical migration of the infill material, and the infill material is the primary source of performance characteristics of the playing surface assembly.
