If I were to build a post and beam shed with a dirt floor to save a few dollars on a cement slab, should I dig down an inch, put down plastic or some other vapor barrier, then put sand/dirt combination back down?
We wish to store items in cardboard boxes and we also will have wood out there. Over time moisture could damage these items.
Would I be better to put a sheet of plastic over the dirt, then put 2×4’s laying flat in a grid, followed by 3/4 plywood flooring. It would technically be a floating floor but would keep moisture out except at the edges. The floor would be built in place after the shed is completed.
Thanks for any opinions on this.
