I have 16" cinder blocks on a flat pad. I'm building an 8x8 shed row style coop in a high wind area. Other than digging down several inches for leveling the blocks, how else should I prepare this step? I was planning on filling the cells and the surrounding hole (which is also just a few inches) with concrete. I'm a housewife, not a contractor. If I were a contractor I'd lay a green plate on top and shoot it into the blocks. I don't want to have to go back and fix something if I can take care of it during the building process. The building will end up being inches from the ground so there will be little "lift" from the wind. I'd love to see pictures of how to lay square off the foundation if you have any.
