I had a basement slab poured in May, and it recently cracked in several locations. I am upset that the cracking did not follow control joints. The slab is about 5" thick, and I was aggravated to find that the control joints are only 1/2" deep. From everything I can find, 25% of slab depth is standard. Do I have a leg to stand on in asking the contractor to recut joints to appropriate depth and repair cracks? Slab is 4k psi with rebar on 2' centers poured over poly, 2" XPS, and ~9" crushed stone, in case it is relevant. Thanks for any input.
