Prepare the Foundation
Having scribed the diameter of the foundation, proceed by digging the footing of the foundation. This
consists of a large circular trench dug just inside the foundation line. (Refer to foundation details for
necessary information.) Once the footing has been dug, you are ready to build the forms. It is important
that the form be rigid enough to hold its shape against the poured concrete. Also, the foundation must be
flat. Sloped floors cannot be used in drying bins. A carpenter’s level placed on top of the 2 x 4 will enable
you to set the top of the forms to match the top of the center stake. Check the form work with a transit to
ensure a uniform elevation for the entire foundation.
