To be honest I really don't want concrete repaired. It's not like a steel girder that get exposed to rust but can otherwise be swapped out with a new piece. If concrete is cracked there is a reason why: something shifted. Raze and rebuild because the earth will never stop settling and/or shaking. Don't they bust up old concrete into new gravel and concrete as well? Probably cuts down on how much land needs to be quarried.
