Leveling an existing 12x12 shed
I have a 12' x 12' shed that is sagging around the perimeter with the inside bowing up or actually not settling. The shed sits on 13 - 14"W x 16"L x 8"T Concrete Cinder Blocks. There are no blocks under the concrete blocks to keep them from sinking in the sandy soil. Don't know why somebody would put a concrete cinder block on its side without another block underneath it to keep it from sinking in the sand. My idea is to put a 16"T Concrete Cinder Blocks. There are no blocks under the concrete blocks to keep them from sinking in the sandy soil. Don't know why somebody would put a concrete cinder block on its side without another block underneath it to keep it from sinking in the sand. My idea is to put a 16"L x 3"T concrete blocks under the concrete cinder blocks. It will raise the shed up 3"L x 3" in the ground, on top of an additional 3" from its leveled height, but should solve the problem of the concrete cinder blocks from sinking. One of my problems is that the perimeter blocks have sunk about 3") and work my way to the other side? What would be some possibilities? I don't want to hurt myself or the shed in the process. And the job should be simple enough to do it myself. Any suggestions or helpful comments would be much appreciated.
Thank You.
