    Per your comment below about 10-15 foot spacing. Control joints on a slab should be 10-15 feet apart both directions. Those are there for expansion/contraction movement. It's a totally different animal with a narrow sidewalk. The joints are not there for any movement issues, they are there to control cracking. All concrete will crack .

    Contraction Joints in Concrete Slabs - The Concrete Network

    Both isolation and construction joints are formed before the concrete is poured; contraction joints (or control joints) are "placed" in the fresh concrete before it has a chance to create its own joints—also known as cracks. What a contraction joint really is in the end is a crack in the slab that we force to follow a line of our own choosing.
