FOUNDATION NOTES:
1. The foundation site should be well drained and free of vegetation and/or debris.
2. Foundation(s) should be on undisturbed soil or engineered compacted backfill.
3. A soil and foundation (Geotechnical) investigation should be conducted
for each site to confirm the soil bearing capacity. Foundation Design is
based on an allowable soil bearing capacity of 3,500 psf.
4. The concrete shall have a minimum compressive strength of 3,000 psi. at 28 days.
5. Concrete should be allowed to cure 7 days before beginning the tank assembly
and 28 days before filling the bin.
6. Concrete should be kept level to ±1/8" in 10' and 1/2" across the diameter.
High spots or debris should be removed prior to setting the bin.
7. Anchor bolts need to be properly located based on the table, found on page
17 of this manual, in order to keep the tank round.
8. All concrete reinforcing rod shall conform to ASTM A615, Grade 60.
9. Rebar should lap a distance equal to (24 * Rebar Dia.). Minimum allowable
lap is 18"- i.e: #6 Rebar has a diameter of 6/8" =.75" * 24=18" or an 18" lap.
Estimates for Rebar do NOT include allowances for the lap.
10. Foundation details in this manual are to be considered general in nature and are
intended only as a guide. It is the owner’s responsibility to provide an appropriate site
and foundation design for the adequate support of the grain bin. MFS/YORK/STORMOR
assumes no responsibility for results arising from these suggestions.
11. The detail below depicts a typical support pad for the aeration pad at the base
of the bin. The dimensions should work for most applications, but may vary
depending on the manufacturer of the fan and transition.

IMPORTANT: Develop a layout plan of the bin, bin accessories,
and auxiliary equipment and then build the bin foundation in
proper accordance with the layout plan.
