Fixing a walkway or building it new
If a few pavers have sunk or spread, they can usually be lifted, the base fixed and the same pavers set back down. A concrete path that's cracked and tipped across several sections is a different story, and a patch rarely holds when the base underneath has given out. I lean toward replacing when the trouble is below the surface, but sometimes you only know that once a section is opened up, and I'll tell you what I find before we go further.
