It's a 1/2" diameter rope like material made for concrete expansion joints, you stick it in the crack and melt it with a torch and it conforms to the crack and seals it, you could probably do it once, or stick two pieces in there to take up the 1" space. It's what you see the cities use on sidewalks.

Crack stix is good stuff since it allows for expansion and contraction. I have used it between the house foundation and the concrete driveway.
