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???
