Hi. I have a concrete basement wall about 12 inches thick and about 8 feet high. The plan dimension of basement is about 24 feet wide and about 34 feet long.
My client is asking if half of the basement wall can be cut out and replaced with new concrete. Keep the footing.
I am requesting comments, code references, and typical details in regard to the two questions below:
1. is this feasible, and would you dowel post-installed reinforcing into existing wall? (a through e general outline)
a. remove backfill where conc. is to be demo'd
b. demo wall, including cutting off vertical steel
c. dowel new steel reinf. into existing footing
d. pour new wall and brace the wall until first-story joists are set
e. backfill w/ bracing in place
2. what is a good way to detail the construction joint? (a and b general outline)
a. apply a bond breaker between the existing and the new pour, prior to new pour
b. waterstop for construction joint (along wall and footing).
Thank you in advance for sharing comments, code references, and typical details.
