When preparing your location for the arrival of the shed, there are several options that will insure your structure has a level foundation upon which to sit.
We have found the best footing is a rock pad. It is best to have four inches of 1" rock and to allow at least one foot additional space around the building.
We have also used a less expensive option... cinder blocks. The ground should be fairly level to use this option. It generally takes about 10 blocks per structure. It is highly recommended that a gravel base of approximately three inches is installed to allow run-off from rain and water.
Please view the diagrams below to determine the placement of block supports based on the width of your building.
