The self-propelled SuperScreed is hydraulically driven and requires only one operator. A strike tube precisely cuts the surface to grade, and is ideal for rehabilitation, panel replacement, and concrete overlay applications. The screed is height adjustable, leveling concrete with a slump as low as 1 in. It can help place up to 10,000 sq. ft. of concrete per hour, and expands from 14 to 52 ft. Its strike-tube design leaves aggregate at the surface for harder, longer-wearing slabs. Multiquip Inc. 800-421-1244.
