    We made the mistake of pressure treated wood straight on the ground with plywood and painted that. Water seeped up through the wooden frame to the plywood so I would highly recommend you put a water barrier or paint both sides of the plywood if you go that route. I wish we had poured a pad. I've seen people do pads like central units sit on and put a few together which should also be fine.

    Hello Beto, you could make a platform with pressure treated wood, ensure it is square and allow about 4 inches space above and beyond the size of the shed dimensions, or you could put pavers down, or sidewalk blocks.

    We used cinder blocks and then pressure treated wood. It has held up very well over the years. I think the secret is keeping the flooring off the dirt.

    When we put our shed in hubby poured a cement pad first. We live in Oregon and get lots of rain so it was a good idea. Haven't had any problems in over 15 years.

    Hi Beto: Depending on the size of your shed, you can dig the area out, about 5 inches, put down some paver sand and pound it down well and them put down some of those paver stones around the edge and across the middle, front and back and put your shed on that. If, over time, the shed leans one way or the other, it will be an easy fix. Good luck
