I have never done this before so it may sound pretty basic. When we do underpinning, how do we want to connect the rebar of each increment? Specifically, we are looking at giving more depth to the walls of a rowhouse so the basements extends to 7.5ft from the existing 5ft depth. We consider doing that in increments of 4ft, with 1ft thickness and the depth of 2.5 ft. I am not sure how the rebar from each segment of concrete shall connect to the next segment. We consider having rebar extend its development length into the next segment. Should that be the appropriate way to connect the segments?
