1. Introduction
ATTENTION: READ BEFORE USING THIS MANUAL
All instructions should be construed as recommendations only. Because actual installation will vary
according to local conditions, The GSI Group, Inc. assumes no liability for the results arising from the use
of such recommendations.
Always make sure to use the correct tables and charts for the bin and soil conditions at building site.
Determine the following before using this manual:
Bin Style
1. FCDL Series
2. “W” Series farm bin (4.00" corrugation)
3. “N” Series farm bin (2.66" corrugation)
4. NCL Inside stiffened commercial tanks
5. NCL Outside stiffened commercial tanks
6. WCL Outside stiffened commercial tanks
7. Commercial hopper tanks
8. BFT/GHT Unstiffened hopper tanks
Foundation Style
1. Floating monolithic pad
2. Frost free pad
3. Inverted “T” foundation or T-Cap
In-Foundation Aeration Systems
1. Tunnel sizing and forming
2. Transition opening requirements
If a foundation for the bin height is not provided, always use the foundation for the next taller tank.
NOTE: A “frost free” pad does not mean the foundation will not shift or be damaged by freezing and
thawing. It is only a term used by GSI to describe that foundation. Always use the inverted
“T” foundation for frost-susceptible soils.
GSI Engineering also has recommendations available for the following foundation options:
1. Hopper cones
2. Tunnels
3. Seismic specifications
4. In-foundation aeration system
