Garden Shed Plywood Floor

[clemsnpaw]

Hi, Let me start this post by saying this is my first time building a shed. I am building a 10 x 12 shed on a solid block foundation. I have 2 x 8 pt floor joist, mud joist & rim joist sitting directly over the block piers (2 blocks heigh). My question is this: I nailed down regular 3/4" AC plywood for the floor.

Is this a mistake? Should I be using PT plywood instead? And what is the easiest way to fix if needed?

Right now I have not stood up any walls so, I can pull of the existing plywood floor if I have too, but it will be no easy task. I'm hoping there might be an easier solution... like installing ACX plywood over top existing. The floor sits roughly between 14-16 above grade with no expected ponding underneath.

Do I have reason for concern?

If there is 18 inches or more to grade below the framing code would allow it to go untreated

is the space underneath your floor ventilated? you could have a problem with moisture and that AC plywood isn't gonna hold up, however, adding some vents could save the floor. I would of liked to seen CCA plywood installed, however, moving air underneath this so called "crawlspace" should be considered I think
