Regarding the concrete slab... Owner of the new store has asked an enginer (structural) to come and evaluate. Here in Mississippi- there's no telling what we'll get for that. In response to a request or mention of a core sample, the contractor said that would only tell us that "One- it is conrete; and two- it has a 3000 mix". The contractor also said that if the floor was to be carpeted, she wouldn't know the difference. He said that this floor holds no weight (steel beams were installed prior to the conrete being poured) and should not make a difference. As far as moisture- he said a vapor barrier was installed to handle that. One structural engineer said that my friend should expect additional cracks and those she already has would probably worsen. My problem is that everyone seems to be downplaying the issue of whether or not this concrete is actually "good"- "they" seem to feel that it won't make a difference. Can someone tell me what I can tell my friend- that she might be able to understand- as to why the condition of the concrete should concern her? like what problems she might run into if the concrete is bad and is ignored? We should have something (God knows what) from our structural engineer soon. (I know this guy and have my doubts, but I can only voice an opinion as I don't really have a dog in this fight.) I do know the contractor is aggravated to say the least- doesn't seem concerned that the concrete is so porous etc. but I expect that from him. He has in turn passed the buck to the guy that poured the concrete- who tried to pass it on to me as I scored the concrete in another section AFTER the crack appeared. One has offered to remove and cut out the cracked area and pour in a patch or to resin fill the crack- no mention of the crumbling etc. Also- these guys said that wxpansion joints or saw cuts weren't necessary- "you don't do those on a foundation for a house and they're fine". Any good arguments out there that I can throw at them? I certainly appreciate this and so does my friend.
