A cinder block foundation consists of a number of cmus set on the ground and leveled so that you can either construct the shed s floor joists on top of them or set a manufactured shed on them.
Step 1 prepare the concrete footings with mortar to receive the first layer of cinder blocks.
Spread mortar on the footings about inch thick spreading only enough to accept three or four cinder blocks or use a trowel to mortar each.
With a taut string water or laser level make a straight line from one side of the foundation to the other.
In some cases the foundation may be level but the wooden floor or beams are warped and cause the house to appear off level.
The only exception was were the footer stepped down and this area required an additional course of 8 block.
Nail them to the underside of the joists as near the foundation as you can.
When the guys pour the concrete floor the concrete will actually conceal all the 8 block and sit on the lip between the 8 and 4 block.
