You need to see what is required in your area. Call the code enforcement and ask them. As long as your footing system is below the frost freeze then it shouldnt matter if the slab itself has a footing system on it or not. City officials are only co

Building a steel building in area where freezing is an issue. Can a pier /floating slab design be used? Or will the slab need a frost footing perimeter as well?

I am sorry I didn't see these replies sooner. I must have omitted to 'watch' this topic and therefore didn't get any notice that there'd been replies. Sorry. It is not exterior and it is not readymix and, therefore I guess, it is not 'air entrained'

How long ago was this done? My guess is the contractor will try and just crack seal it to get away with it... which if your worried about cosmetic will look worse...

I don't think there's much you can do about crazing. Those types of cracks are just on the surface and are strictly cosmetic. I'd be much more concerned about the other cracks caused by the lack of crack control joints. It doesn't look like he pla

I doubt that it's a chemical reaction from chlorine. Probably just stains from where pool water got on the deck and evaporated, leaving chalky residue. I assume the concrete has been well-sealed? If so, try scrubbing with a little vinegar in an in
