My husband and I are wondering if it is possible to install a wood deck over a regular concrete covered patio (north facing, so almost no sunlight hits it - just a little in the morning). There is one thin crack running most of the width of it (developed about 1 year ago, got ever so slightly wider (1/16") over the next couple months, but now stable), but that is the only flaw.
We plan to screen in the patio, then "extend" it by installing a wood deck on the other side of the screening (for those times we'd like some sunshine:). We thought it would look great to place a wood deck over the covered patio, too, making it look like one large deck, half covered and screened.
The patio is currently approx. 15' x 20'.
If this is feasible, are there any special preparations we need to make to do this? Or can we just lay down some heavy-duty plastic sheeting to keep the moisture out of the wood, put down some plywood and attach the decking material to that?
Any thoughts on this???
