Abstract
A concrete crack control system is provided. The system comprises a vane or angle projecting from a wall, such as a pedestal or column or other wall surfaces against which a concrete floor or slab is poured. After the concrete has set to firm consistency, a saw cut is provided of a substantial depth in line with the projecting vane. The exposed saw cut may be filled with conventional filler, such as grout or the like. Any tendency of the floor to crack upon aging will be along the line of the vane and saw cut, thereby preventing crack damage to the floor.
