I was wondering if I could get some advice on the best way to tie a new foundation to an old one.
Here are the particular's of the job:
The prexisting foundation (60+ years) is concrete block, with the old wavy textured exterior.
Here are the questions:
1) Would a poured concrete basement addition be better to tie into the old one, or would a block basement be best?
2) What's the best way to physically tie these foundations together?
3) Is the old textured brick going to be a problem?
4) Is it possibly to 'share' the basement wall between the two basements, or would another one need to be built along side of it? (Which way is best?)
If this issue is too large to cover, maybe someone can tell me if I can still epoxy rebar into a block wall to be secured by pouring the new foundation wall next to it? Would I need to grind off the textured sides of the pre-existing block wall? (The basement is walkout, and totally exposed, hence the pretty blocks used.)
