Place the Reinforcement
Once the forms and trench have been prepared, begin the placement of reinforcement rods at various
levels in the foundation’s footing. See the appropriate charts and drawings in this manual for the bin to
determine requirements and positions of the reinforcement. The reinforcement rods offer their greatest
strength when lapped properly and connected by wiring or welding. Next, place a minimum of 2" of
compacted sand on the inside section of the foundation to provide a good base for the concrete and
protect against rodents. The sand should then be covered with 4 mil polyethylene plastic, which will act as
a moisture barrier. Two (2) layers of 6 x 6 wire mesh should then be added to the entire area of the
foundation to complete the preparation of the bin’s foundation.
