PNEG-1093 2.66" Corrugation Unstiffened Bin 17
Placing the Reinforcement
1. Once the forms and trench have been prepared, begin the placement of reinforcement rods and
mesh at various levels in the foundation’s footing. (See the appropriate charts and drawings for the
bin to determine requirements and positions of the reinforcement
on Page 18-26. ) Reinforcement
rods should be properly lapped by wiring.
2. 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.
3. The sand should then be covered with 4 mil polyethylene plastic which will act as a moisture barrier.
4. Two (2) layers of 6" x 6" wire mesh should then be added to the entire area of the foundation slab or
the entire foundation for monolithic systems to complete the preparation of the bin’s foundation.
