I want to replace my 10' X 10' deck boards with exterior treated plywood to make the area under the deck water tight, I would .like to then put outdoor carpet/astro turf on the deck. I then plan to enclose the area under this deck with an enclosed area with vinyl windows and storm doors to extend the seasons a bit. The entry into this new room from my house is from my walk out basement out to the level where my pool is.
So the question is, will the plywood stand up over some years to being almost flat and not delaminate etc.
Thanks, Rich
