Attatching old concrete to new

bill333

Hello all:

I bought a repo cheap, one reason was foundation. Most of the house has a good footing and stemwall. The problem..........the addons were set on cinder blocks and now the two new additions are trying to pull away from the old house. I will have to pour new footing and stemwall under the house. I am afraid i will have pour it in four foot sections. Once I pour how do I attatche the pieces together?

Install rebar in the new concrete for connection to the next section.

& since you'll be placing new conc onto/against old, we'd coat the existing w/epoxy for a ' grout ' & paste to grout the ' new ' old conc,,, can you btw, install using a hop-skip method ? ? ?

Dowels, drill holes in existing walls put dowel rods into holes and secure them , run them over to the new footings , once you pour it's staying there.
