My house currently has a 3rd car garage that I would like to convert and extend my family room. The biggest question is how to raise and level the garage floor with cement (preferably). I spoke with the city and the fact that there is no vapor barrier is not an issue. However, the thin 1 3/4 inch pour at the shallow-end seems to be an issue. It sounds like my options are:
1) Place rebar in the stem walls (and adjacent foundation) at 16" on center and use standard concrete. From what I read the pour is too shallow already and adding rebar to the shallow part could risk cracking.
2) Use wire mesh instead of rebar to reinforce the concrete (I am not sure if this is acceptable in the CA building code or if the strength is all the matters?)
3) Use some sort of cement/fiberglass mixture. This was a contractor suggestion but I don't have any details.
4) Use a polymer concrete that is designed for this depth. The only problem with this is it will be more expensive and I can't find any mixtures specific to my depth.
