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.

Hi Brian

If u have a metal shed and used the floor beams that came with kit, they are not designed to carry much weight without support from the ground.

When I installed my 12' by14' metal shed, used 4'' block on flat. Filled and packed inside of area between block frame.

Four people helped me carry shed (fully assembled) and set it on block.

My shed is all wood. It has a 2x4 frame on bottom and all 4 sides. I am pretty sure that it was built in place, not manufactured. It is basically going to be like leveling a house w/out the sheetrock.

Raise one complete side at a time. Install 1by4 diagonal brace from floor to ceiling on walls perpendicular to side u are raising.

U should be able to do this with 2 jacks.

Pour 3 2' by 2' concrete pads 6'' deep. This will give u a large foot and aid to keep from sinking in future.

Good luck
