I have a low spot where rain/snow melt pools in a stamped concrete patio. There is a small crack that runs through the low spot.
I know it's not an ideal situation as I live in an area that has freeze thaw cycles. Skim coating the area doesn't seem practical because of trying to match the color/stamp pattern.
I caulk the crack each year and put patio sealer over the top.
Is it better to leave the low spot as is, drill a small drain hole through the crack, or to add a relief cut so that it will drain somewhere?
Thanks

If I understand the situation, a hole wouldn't really do anything except let a bit more water get under the slab...where it will also be affected by freeze/thaw and cause more problems.
A cut could help, though I don't know how far that cut would have to be to get it sloped so the water leaves.
For now, caulking is probably your best bet in terms of simple solution.
A more complex solution would be mud jacking where they come in and drill a few holes, then pump in back-fill to raise the concrete back to the proper slope.
