Multiple Repair issues

[Sully]

OK, I am going to throw another angle into the picture....the areas on the deck where its cracking. If you walk on these sections, does it sound hollow? I have a neighbor that had to have her deck ripped out and replaced due to the rebar corroding. I thought the contractor was pulling a scam, until my BIL told me that it was quite possible.

Not to sound really ignorant, but do you mean the rebar in the concrete of the deck? This is becoming more and more interesting.........

[Sully]

Yes, the rebar in the deck.

I'm sorry, I didn't think that was possible for rebar being inside sealed (no oxygen) concrete to fail. But rust is rust, and not Ever being in the concrete working industry, I guess it could happen. Did you happen to see the concrete in question when they tore it up? I am going out to check it tomorrow morning and see if it's hollow sounding. Thanks for the tip.

i think if you intend to leave, get the quotes...if i were going to look at buying your house, that's what i would do, which also potentially slows down the sales process..lack of info is likely to lead to lowballing..while slab and mudjacking are great options to fill voids..make sure you ask the right questions including if they can guarantee that it won't cause heaving in other areas of the deck..when i had my garage pad and section in front of garage done, both contractors i had give quotes told me it is an imperfect science and can potentially cause over correction of the pad (higher in an area for example) that being said, one was confident enough with his experience that he guaranteed he would take out and re-pour a pad section if it over corrected..the other would not. my results of the slab jacking were that it was much better..but not "perfect" in terms of the level of the pad. (in short, i wouldn't put a level on it and expect it was perfect) you can see it is not perfect, but given i had a 1 inch to 4 inch drop and basically it now goes from perfect to 1 inch out, i can live with it..but, it's a garage floor, not a pool deck if it were me and i was getting slabjacking done and selling the house, the amount "out" i indicated would be good enough for me..and i would have a copy of the slabjacking bill to prove the work had been done to fill the void to the best ability..beyond that, if not good enough for the new homeowner, i'd let them deal with it
