I need a foundation for a 4 x 5 resin shed. Intend to lay it on gravel and fill in 2 additional inches of gravel within it's frame. Would this work. Some leveling would be required but may not prove to be difficult. What are your opinions?
That should work as a a foundation. The foundation kit is intended to be used as a replacement for a Concrete slab. You put this down and build the shed on top, then you use plywood for the floor.
