Groovers
Jointing the concrete is accomplished by grooving tools (unless the slab will be sawcut later). The purpose is to control the location of cracks that may form when the slab "contracts" due to drying shrinkage or temperature changes.
Look inside tooled joints or sawcuts and you will see the concrete is cracked—The joint did its job and controlled where the concrete cracked. Joints are most often hand-tooled into sidewalks, driveways and patios and sawcut into floors, highways, and city streets. Get more information on joint layout and required joint depths.
