@bdavis466 - hoping for your advice please! We're in the middle of a remodel, pool is demoed and they are currently fixing the cracked areas in the bond beam. They are just adding new cement without using any rebar to tie in to existing structure. PB says he doesn't recommend adding rebar because it can weaken the bond beam since it's so thin. I read where you'd mentioned if the concrete put in was less than 4" you don't need rebar. In your opinion, are we ok not adding it in this situation? I also do not see any bonding agent being used. I've attached photos of the mortar bags. Thank you for any help - the work is being done today!!!
