how to repair concrete step with big crack
 

Hi, out front of my house i have a step with hug 1" crack in it all the way around. I think the pad in front of it sunk and took bottom of the step with it. I bought some of that "big stuff" insulation expanding filler yesterday to fill the crack. Will this work for a quick fix? Any other suggestions on how to fill a crack this size?

Hello MayHem:
It appears the sidewalk or pad has sunken away from the step. It is possible to dig a small hole on each side of the pad, jack it up and stuff sand or small limestone in the void to hold it up. Then the crack would be a simple caulk job to keep water out.
