I built treated wood deck. I also am building a paver patio off this deck. Well my question is this, I want to build the steps (2 to 3 steps) out of treated lumber for a frame and the riser, with pavers inset as the tread. What is my best way to do this? Not really in the construction, but my concern is drainage. If I just build frames and set them on top of patio pavers I will not get adequate drainage and my frames will rot. Any suggestions, ideas, is very appreciated.
