I messed up...suggestions

[papabear]

I orderd a prebuilt storage shed a week or so ago.It is 12x20 painted and shingled to match the house.They deliver it on a hydraulic trailer and can set it any where you want it with virtually no effort.My problem(or what I feel is a problem)is I forgot to specify I wanted a treated floor put in this thing.I laid awake most of last night trying to figure out how to fix my screw up.I have no water issues.The yard is high and dry but my concern is moisture from the ground rotting the floor from below.I do not want to be fixing this thing a few years down the road.
What my thought is,and if it's lame please tell me,is to lay some visquine(SP) down than lay sheets of 1/2 or 3/4 treated plywood over that than set the shed down on the treated plywood.Than I would saturate the floor on the inside of the shed with a quality brand water proofer/sealer.This may be overkill but I would rather be safe than sorry.Cost is'nt a big factor here just due to the fact I am saving thousands of dollars compared to building a conventional garage.All it is intended for is storage of extra garage items.Thank you for everyones help.John

I think you are over reacting to this- Is the floor of this shed going to set directly on the ground? I hope not- I would want it to be on some sort of pressure treated structure, thus keeping the actual floor away from the ground. In my less than professional opinion, this, with ventalation should be fine. I'm sure there are other thoughts on this.

Can you jack it up and put it on some blocks? Maybe some solid half blocks?
Shim it to level.

I wouldn't be too concerned about it, I am sure it will have a PT plywood floor. It will take years for it to rot if you do nothing at all. What you might want to do is prepare the place it is sitting with a moister barrier covered with gravel. I would also be sure that water will run away from the building and not pool around it. If it doesn't have gutters install them yourself. You are pretty vague about what you are setting it on. Moisture from the ground is what with rot your building regardless of what the material is. From what I gather from you post the building has not arrived yet. You, I assume have to grade out the area anyway. I would not use Plywood of any kind on the ground. That will only accelerate the rotting process. A moisture barrier can be a simple as clear plastic or rubber roofing. when they deliver the building be sure to have plenty of paver's, 1 foot lengths 2X6 and 1X6 to shim and level the building. Do not assume they will have all the materials to shim it the way you want it.

IF - After reading the above solutions, you still want to do something. Why not build a PT 4x4 structure for the building to sit on? It will be some work on your part, but it will ensure the building is level and stays that way. It will also last a lot longer.

Sorry for not explaining well enough guys..my appologies.The floor joists are built with treated lumber than the floor is installed than the rest of the building is constructed.The floor WILL NOT be resting directly on the ground.The treated plywood floor is an option from the builder.Thanks again everyone.John

If you can, Go with the treated plywood on the floor. If you can't, Make sure the untreated lumber or floor plywood is at least 8" above the ground. If you have to raise the building use 8" concrete blocks around the perimiter and probably a row down the middle.

Based on this statement, I would not worry about it at all. Some ventilation under the structure is always a good idea, just make sure you can keep the critters out.
