NW Ohio,near Findlay | Dana, your profile doesn't give location, but if in frost area, must have footer. At my away from farm job, excavating business, we have dug numerous footers for bins. A few have tried a trencher, a small one and tied to center piviot point. Getting a wide enough trench is a problem, and cleaning out crumbs in bottom is about impossible. Best way is a mini excavator, with a foot wide bucket, (18 inch works better) and do a little hand work with shovel, go around circle. Then you can work in trench,pre install rods or most guy install when pouring. Lots of guys us 1 inch blue insulation on outside wall so frost will not go through footer and freeze under bin. If insulation board has voids between dirt and board, does not make a different on outside, no weight there, only will fill in with time. Then you can use blue board to kind of make smooth pour at top, back up with stone, makes it look better if grade is not quite level when footer poured. Now you can pour your floor on top of footer and be safe from frost, rats, and settling and cracking at outside. Must be a trend in the bin industry to say don't need footer becasue weight of grain is even, only steel weight of bin is more on outside. Maybe and only maybe in some areas you can get by, not not worth the risk. | |
