Shed floor rotten again.

[Jsf721]

It’s a ply wood floor covered in interlocking tuff tile. Shed is 12x 8 approx.

I put the snow blower away for the season And it’s shot. Replaced it 2 seasons ago for the same reason. I guess is water intrusion from under because it’s dry inside. I have not pulled anything up yet as I’m trying to formulate a plan so I can fix it and reload it hopefully in one weekend. With my job it’s tbe only time I can work.

I need some help thinking through a total solution from finding and Solving the root cause and then getting the correct base flooring material. Do they make a Trex product in sheets ? Do you think topping the floor with tile is causing moisture to be trapped. I added it to make cleanup easier. It’s a storage shed to free up space in my 2 car garage. Since adding the shed I can get one vehicle in the garage.

Thanks

I'm guessing its because you are covering the plywood and it's not letting it breathe/dry out.

How much air flow do you have under the shed?

Id tend to think it lacks ventilation under the shed itself causing issues.



My parents have had the same shed for 20 years. It sits on a bed of gravel about 6" deep and the shed itself sits on 4x4's. The ramp rotted because it sits on the ground, but the shed floor itself is fine.

Ya really has the shed sunk in and the floor like touching the ground or sits in a real wet spot? My yard shed still has its original floor after more than 25 years. .

I really don't believe using the tile is the root cause of the rot.

The cargo trailer I use for storage has lino over plywood and I recently found a bad spot in the floor by the rear door, and that always sits like a good 8" off the ground...but water leaking in by the door is what caused that.

Pull up the rotted floor and staple down METAL window screen across the floor joists. Use pressure treated 2x6's as the new floor and you shouldn't have any more issues. The screen keeps the bugs out and there air will be able to circulate through the gaps in the flooring.
