I have an existing concrete walkway that’s in pretty good shape. Can I lay pavers over it?

While not the preferred method, pavers can be laid on top of existing concrete walkways. Two issues must be addressed. First, the grade will be raised by about 3″ (the thickness of the pavers plus the bedding sand). This is particularly critical if any doorways are involved. Second, if the existing concrete slab should raise or drop with freeze/thaw conditions, then the pavers will do the same.
