One panel of our sidewalk is original stone (not concrete). However, there are some large cracks around it (where the stone and concrete meet) and there are some dish-like divots in the middle. Kind of like scaling, but on solid stone. The stone is also slightly lower than the surrounding sidewalk, so we're thinking we can just do an overlay. A couple questions though:
1) Will doing a concrete overlay on stone work?
2) How do we handle the large cracks and the shallow overlay? My understanding was we use the premix (with gravel already in it) for the large cracks, but several areas will be only 1/2 inch thick, so it seems like we can't use gravel. Do we use no gravel anywhere, or do we mix two batches (one with and one without) and layer them together?
3) Our books say to do concrete when it's 60-50 degrees. Looks like the weekend is not going to cooperate though. (They originally said 45, and now they're saying 30.) Can we still do this when it's cold? Any special precautions?
Our goal is not to have a long term solution, but at least get us through a couple years with something reasonably flat.
Thanks!
