I'm facing a situation where the plywood floor of my shed is sitting directly on the dirt beneath, and it tends to get damp. I'm looking for effective ways to create an air gap to prevent moisture buildup. Access to the shed is limited; I can only reach it from the side, not the longer ends. I considered digging some dirt out and using a rake to lift it, but that sounds like a lot of effort. I also have an air compressor, and I'm wondering if I could use it to blow out dirt from under the shed—maybe by attaching a small pipe to a blow gun? I have both standard and high-flow types. Just to clarify, the shed rests on treated beams on the front and back edges, and the ground is pretty muddy around it. I think lifting the corners with some bricks or pavers could help, as suggested by another user, plus open up airflow to prevent rot on the damp side. What do you think?

By the way, I noticed the pictures you included aren’t showing up properly. You might want to provide the Imgur links directly in case others want to check them out!
I recommend lifting the shed at the corners and sliding a brick or paver underneath each one. You might even consider putting a block in the middle of each side for extra support. If it were me, I’d jack it up and place some 4x4 posts under it to better distribute the weight and elevate it off the ground. This will really help with airflow and keep that wood from rotting!
Yep, wood deteriorates fast when it's touching the ground, especially if it’s untreated. Lifting it is definitely the way to go!
Thanks for the heads up! I linked to the images in my post; maybe they'll work better that way.
