Fixing a walkway or building a new one
If a few pavers have sunk or tipped but the rest of the path sits level, we can usually lift that patch, rework the base under it and reset the same pavers. When the whole path rocks, cracks across its width or holds water along its length, the trouble is usually the ground underneath, and patching on top just moves the problem around. Then I'd rather take it up and build it again on a well-packed base. I'll tell you which your path needs, and whether it can wait.
