I'm working on a project where we are designing new rollover curbs on top of existing paving to as part of containment etc...
There's a 5' long portion of an existing reinforced concrete trench running perpendicular to the curbs that we'll have to cross over and will need to backfill with a water stop. I haven't ever backfilled an existing concrete trench, is this something as simple as roughening up the existing sidewalls/lower portion and applying a bonding agent before pouring? I haven't had any luck finding any type of information on the subject.
