Roof Damage Warning and Disclaimer
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
DC-969
CAUTION!
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air”
devices should be provided for all powered air handling systems. The manufacturer does not
recommend the use of downward flow systems (suction). Severe roof damage can result from
any blockage of air passages. Running fans during high humidity/cold weather conditions can
cause air exhaust or intake ports to freeze.

3. Foundation Requirements
Foundation Requirements for Top Dry Bins (4.00" Top Dry
Bin Corrugation)
Requirements
The following foundation recommendations are a revision to earlier manuals distributed by the
GSI Group.
NOTE: There are changes in foundation dimensions from past publications. These dimensions are critical
to the proper installation and function of each foundation.
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The bin can be installed
satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the
foundation. The concrete foundation surface must be level. If some fill is required, it should be watered
and tamped thoroughly to prevent uneven settling from the weight of the bin. Naturally, the site must allow
convenient access for easy loading and unloading, plus provide additional space for future units. Also
considerthepositioningofhandlingequipment,availabilityofelectricityandtheplacementoffans,heaters
and gas tanks.
Scribe the Diameter
Having determined the center of the site, drive a small 2 x 4 in the ground to mark the center point of the
foundation. The top of the stake should be the same height as the finished foundation will be. Using one
large spike, nail a straight 2 x 4 (approximately 2' longer than the radius of the bin) to the top of the center
spike. The swiveling 2 x 4 will act as a compass, enabling you to scribe the correct diameter of the
foundation and later locate the anchor and stiffener bolt locations. (NOTE: Making the 2 x 4 2' longer than
the radius allow the 2 x 4 to also be used as a leveling device and for pulling concrete.) (See Figure 3A.)

Circular Foundation Form
Figure 3B
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. (See Figure 3B.)

Carpenter’s level

PNEG-1510 Top Dry 24', 30' and 36' Manual Batch 11
Octagonal Foundation Form
There are two (2) styles of foundation forms commonly used. The first is the circular form depicted in
Figure 3B on Page 10. The second style can be made of 2" x 8" boards set into a square with corners
blocked off to form an octagon. (See Figure 3C.) This eight (8) sided form will approximate a circle and
can be constructed quite easily.
When the foundation form is completed install reinforcement rods by either welding or wiring in place.
Place 2" of compacted sand on the inside level of the foundation. The sand is then covered with a 4 mil
plastic moisture barrier. 6" x 6" Wire mesh (two (2) mats), covering the entire area of the foundation,
completes the preparation of the bin’s foundation. You are now ready to begin pouring concrete.
NOTE: All concrete is to have a minimum compressive strength of 3000 PSI at 28 days.

Inline Centrifugal Fan Pad
Placement of the Fan Pad: GSI Transitions/Fans only.
If a fan is to be installed, refer to Figure 3D to determine the concrete pad size.
1. The top of this pad should be level with the top of the bin’s foundation.
2. Recommended pad thickness is 4" minimum.
3. Front of pad should be perpendicular to bin wall.
4. Pad for heater not required.
IMPORTANT: Fan pad and fan must be leveled and smooth for proper operation. Vibration problems can
result from improper fan leveling.

Duct and Drying Fan Pad Optional
Placement of the Duct Fan Pad: GSI Top Dry Duct System only.
Refer to Figure 3E to determine the duct pad size.
1. The top of this pad should be level with the top of the bin’s foundation.
2. Recommended pad thickness is 4" minimum.
3. Front of pad should be perpendicular to bin wall.

NOTES:
1. Foundation site should be well drained and free of vegetation or debris.
2. Foundation design is based on a minimum soil bearing capacity of 3000 lbs/ft2. If soil bearing
capacity is in doubt, contact a local soil testing engineer.
3. Concrete shall have a minimum compressive strength of 3000 PSI at 28 days.
4. Requirements for reinforcement do not include overlap.
5. Lap all circumferential bars 35 bar diameters and stagger all laps in plan 3'-0".
6. All material used for backfill inside the ring wall should be a clean, well graded, crushed stone or
sand-gravel mixture. Backfill should be placed in 6" lifts and well compacted.

Anchor Bolt Placement
Having poured and leveled the concrete, use the center stake and straight 2" x 4" again to find the bolt
circle radius for the outside hold-down brackets. Select a starting point and stretch a pre-measured chord
along the imaginary circle formed by the bolt circle radius. Take into consideration the placement of these
bolts so as not to interfere with the positions of bin doors and transitions. (Refer to below Chart for
necessary radius and chord lengths.) Take the time and work carefully since accuracy is important.
Work both directions from first anchor bolt location, this will help eliminate possible error in laying out
anchor bolts. On larger bins sight across starting anchor bolt and center pin and place anchor bolt on
opposite side of anchor bolt radius. From this point you can work both directions from both anchor bolts.
NOTE: Top edge of slab where the bin wall sets must be held to within 1/8" of level.
