Existing - New basement wall connection
Existing - New basement wall connection
(OP)
I need to connect a new wall into existing wall. The thing is I am connecting it it in the middle of the wall span. How do I know that dowel epoxied 6" into the existing at 16" o.c. is good enough to make the combined wall as one unit (instead of a hinge point in the middle). My new wall is going to be reinforced 16" o.c. both directions. How do I figure out the development length of the epoxied #5 rebar?

What type of masonry, thickness, wall support configuration?
What are the supports at the sides, top and bottom? Can you make it span the other way?
Need to know more before we can give you any decent advice.

Check your footings.
If this is a cantilever wall then you may only have reinforcement on the outside face, no help for spanning.
If it is only 3' high, it would be a much better job (and probably cheaper) to demolish the 3' of wall and build a new full height wall.
Would recommend hilti HIT RE500 for reinforcement bonding, they have charts that give required depth for full development.
CMU may be cheaper than concrete in this case, particularly if there is no other concrete work on site.
