25 degrees, hm? I'm going to assume you mean Fahrenheit. ;-)

What you see there is concrete "spalling" -- and an incredibly bad case of it, at that. It happens like this:

When your concrete slab was poured, the contractor probably "creamed" the surface to give it a professional, polished look. Unfortunately, as the concrete was curing during these freezing conditions, water seeped underneath this delicate 'creamed' surface and froze there. Water expands as it freezes, and it caused the surface to "pop" off, which is what you see there.

I am 99% sure that's what happened here. If it is, then it would definitely be the contractor's fault.

If the contractor won't help you, your next step would probably be the Better Business Bureau, or some similar consumer protection agency. Also, it won't get you any money back, but you could tell your story on review sites like Google's Business listing to help warn other homeowners away from bad contractors.

We have seen this before the cause is pouring when its too cold. What happens is concrete has water in it when temperatures drop below 32 degrees and freezes thats ok but the concern is when the concrete thaws the water needs room to expand. What happened to your concrete is called top pop. which is where the top pops off due to freezing and thawing of water in the mix. Never pour in cold weather unless you have concrete blankets and some form of heat. After seeing your photos, you should remove all of the concrete and start over. visit Avoid Concrete Mistakes - 911handyman.com | 911handyman.com or Completed Project's - 911handyman.com | 911handyman.com

it isn't spalling but it IS a frozen top,,, not sure who supplied the conc but there should have been air in it ( air entrainment ),,, know many of the guys who place & finish conc around augusta/aiken/etc,,, i would suspect whoever did the work never anticipated such low temps & had little experience in handling the threat,,, scarifying the top 1/2" ( or as required ) can be an acceptable repair however you did pay for an acceptable job,,, hopefully you can find someone who will be able to ' persuade ' the contractor to do the right thing !
