Thanks for the warm welcome.
After removing the plaster from my pool I found this Crack on the side wall.(Sorry posted it sideways) My plan is to channel cut the crack with a wet saw until re-bar is exposed , then hammer chisel the rest of the way leaving the re-bar in place. The crack is inline with a proposed main drain and suction line replacement project. The project will replace 1 drain with 2 drains to avoid entrapment s and upgrade the main drain suction to 3 inch. I had read in a similar post how Anchoring concrete was recommended in patch work. Does this plan seem correct? Any and all help is appreciated..
