KY | Ordered bin today to replace one that finally gave up the ghost after 20 years or so, replacing a 3 ton with a 4.5 ton. The 3 ton sat on a 4" pad, never got the first crack in it, tore it out last year as when the bin came down extended calf lot into that area a little. Manufacturer recommends 11" of concrete, which seems overkill, but lots of psi on those four legs. I would think 6" with mesh or rebar would be plenty with a strong psi concrete, anyone else have a small one like that on a non-11" pad? |

Amherst WI | Maybe this is stupid but could you use sonitubes under each leg and fill them with concrete? |
|

KY | Don't really see why not... all the concrete in the center of the bin where the legs aren't touching is just "there.". I would figure a 8" tube 18" deep would do the trick... but just guessing. I guess I'd just as soon have the pad just to keep it neat under there, either that or soak it with pramitol and put gravel beneath it. |

SE SD | hinfarm - 3/4/2016 21:11 Maybe this is stupid but could you use sonitubes under each leg and fill them with concrete? Yup, works good till one shift. Pier legs also suck if you have a bucket fill underneath.
Alot nicer to have concrete to slide buckets on. :) |

north west arkansas | I drilled post holes where my lefts were gonna set and filled them with concrete and put a slab under the whole bin. |

Whiting, Iowa | I've got a 7 ton bin on a 6 inch pad that hasn't cracked. I'm sure it wouldn't hurt to be thicker on the corners. |

Trenton, Missouri | We put a new one in. It is a 6 1/2 ton plastic one with six legs. I didnt see anything about how deep to pour so I poured it at 4". I dont really see us having any problems with it but what do I know. You could drill some pier holes right where your legs will go and then pour 4" - 6" on top of the piers (footing holes). It is probably redneck but I have laid several pads with those in them to keep them from heaving a corner up and so far in 10-15 years I havent seen them fail. It is pretty nice to have the crete there to work on. Also mine didnt come with any way to attach the 16' auger and motor. I called the guy I bought it from and he said that most of his guys put them in a building and support the auger/ motor with a wall. I said "thanks for telling me my pad is in the middle of nowhere". We welded a redneck frame on it with wire rope supports. The only steel on mine are the legs and they are only about 7' tall and my auger went about 12' in the air the rest is plastic. Good luck. |

| 6" works here |

south central ill effingham county | 8 inch would be plenty with wire mesh |
|
| |
|
Northern New York | 6" is fine. 11" sounds like major overkill. You are talking a 4.5 ton bin here........
With wire in it you won't have an issue. |

western iowa,by Denison | make it 18inchs thick-probably have concrete truck come out and its a small pad-3 yard minimum-its a $300 dollar vs $100 dollar question-three yards is $300 here
First question what size pad?second ? hand pouring or truck? Third question how many yard minimum on truck pour?
4th question-? since it's concrete pour do you have beer on hand? |

East-Central Ontario | I have a 5 ton that has sat on two 5" steel pipes as skids with a couple of cross braces for 20 years, been moved several times (always mostly empty), never had a bit of trouble with it |

Forget the columns and pour the pad. It keeps the weeds down under the bin and makes it much much easier to clean up spilled feed.
All of our feed bins (5 ton 4 legs all the way to 12 ton 6 legs) are on concrete pads poured using 2x6 form boards.
If your base is good that concrete will never crack.
We've got 24+ ton ingredient bins that are sitting on 12" thick pads.

KY | Garvo, same here, $300/3 yd min. If i just do the pad, probably just pour it out of my 3 pt. mixer... If I call for a truck I could use a pad under my 3 yd dumpster and a couple other small things. Need a 24' bin pad too but won't be ready for that by the time I need the feed bin set. Plenty of concrete to pour, got the brew if you wanna drive down and be the foreman! |

Kingston,Mi | We have a 6 inch pad about 8 ft. square under a 300 bu. feed bin, minimal re-rod reinforcement, no cracks and the cost was $0.00. left over concrete from a county bridge project, they just wanted the form work done and ready when they would randomly appear. Its been up for 15 plus years. |

Alton, Ia | 11" WOW.
We've got a 12 ton bin on a 6" pad, poured 30+ years ago, no cracks. We did dig down under the leg spots, IIRC, maybe a couple inches.
If like another poster mentioned, you'll have a minimum charge, pour a bigger pad. Concrete on a farm is kinda like that celebrity comment I heard once- "you can never be too rich or too thin".
What's as or more important than concrete thickness is the prep underneath. Good solid clay, pour thin. Squishy silt, pour thick.

frederick, MD | I have 2 28 ton bins sitting on a 10 inch slab. For 10 years. |

Galena IL | Do the math. 4.5 T = 9000 lbs / 3 is 3000 lbs /leg. My semi has 12000 lbs on its front axle or 6000 lbs /tire. My machinery storage shed has a 4" concrete floor poured 40 years ago, none of my semi's have gone through yet... Dennis |

west central wisconsin | 12 inch thick pad here for all bins, 12 to 30 ton,. As was stated, the minimum delivery gets most of it done. If a larger bin goes in at a later date, you will always be good to go.
Yes a couple of railroad ties will keep it from sinking in, but when empty, one strong wind ruins a bin, auger, and boot when it tips over.
Cheap insurance to pour a deep enough pad, that is wide enough to hold any size bin. I assume that is the reasoning the manufacturer recommended the thick pad. |

Bulk bin pad...??
