Repair Large Cracks in Concrete

[K. Smith]

Fillers such as epozy can be used to repair small cracks in a concrete walk. At what point will fillers not work? What method(s) should be used to repair larger cracks, say 1/2" wide? What about 3/4"?

Jack hammer....new walk. If it were a foundation the answer may be different but probably not different. Serious crack in any concrete. Major work is needed.
