Bowing cinder block basement walls
would It be a good idea to just re frame the basement with 2x10 against the cinder blocks. Would this stop the walls from bowing, there is no water leakage.
No not a good idea, Call a professional foundation expert. The outside earth is pushing against the cinder block and pushing it in and the more it bows the more the weight of the building above transfers from pushing straight down to pushing down and inward.
