5. Foundation
Foundation Recommendation
These foundation recommendations are of a general nature. Site conditions, system requirements, etc.
May result in foundation construction requirements not covered by this manual.
Selecting the Proper Site Location
1. The selected site should be level, firm and free from underlying debris. The soil bearing capacity
should be equal to or greater than required by the footing specifications.
2. 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.
3. Naturally, the site must allow convenient access for easy loading and unloading, plus provide
additional space for future units.
4. Also consider the positioning of handling equipment, availability of electricity and the placement of
fans, heaters and gas tanks.
Scribe the Diameter
(See Figure 5A.)
1. 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.
2. 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.
