The back patio I have now is concrete with nothing on it. Can I just put paver stones on top of the concrete?

Answer #2 · Chason Arthur's Answer · If you've got the right amount of clearance you can. Depending on the thickness of the paver stones or brick you will use, you'll need at least 3 to 5 inches of clearance from the top of the concrete to the base of your door's threshold. Otherwise, if you don;t have this much clearance, you might need to look for alternatives: slate stone or some kind of durable patio paint or cover.

If you're set on pavers, then you will have to remove the concrete to install them properly. I used to own a construction company in D.C, and we would always excavate to 7 to 8 inches below grade/ground level. Then you install 4 inches of class 2 base and screed an inch of sand. Then you'll lay the paving stones. Then compact, sweep joint sand in and compact again. It's not too hard to do...excavating is the hardest part.)

Answer #1 · Chason Arthur's Answer · Maybe. If there is at least 3-1/2 inches of clearance from the top of the concrete to the threshold of the door you can do it. If this much clearance is not there you will have to remove the concrete.)
