North Carolina | I'm going to move my 12,000 gal aluminum nitrogen tank.
And need to pour a new concrete pad. But Im also going to put a 2000-3000 plastic water tank on it also.
So the pad is going to be roughly 12ft x 24ft.
How thick should the concrete be. |

|
| What is the diameter of the tanks, and what will they weigh when full ?
With those numbers you can calculate load, and psi. |

North Carolina | 10ft diameter. Filled with 32%. I think it weighs around 11lbs or so.

Kingston,Mi | First is this a vertical or a horizontal tank? You said aluminum, so I think immediately of a "bullet" tank or a horizontal tank on concrete stands. If it is horizontal and is not going on new concrete stands, we have seen them laid on railroad ties on a re-inforced concrete floor. If it is a vertical tank and is 10 ft. in diameter then it would be approximately 20 ft. tall., 20 cubic ft. of product at 11 pounds per gallon x 7.48 gallon per cubic ft. =1645.6 pounds per square ft. or 11.42 pounds per square inch.
I have designed and supervised the installation of 30,000 gallon tanks vertical tanks ( 36 ft. tall) 36cubic ft. x 11 pounds per gallon x 7.48 gallons cubic ft.= 2962.08 pounds per square ft. or 20.57 pounds per square inch. These tanks went on to 6 inch re-inforced concrete. |

| We have a 6,000 b gallon vertical tank on an old 4" hog lot slab that was poured in the early '70s and I doubt it has any reinforcements in it. Tank has been there since 2001 with no problems. |

North Carolina | Vertical. Upright |

Statesville, NC | My main concern would be what's under the concrete. If its solid subsoil you don't need as much thickness. If there is any fill of any kind, I would go thicker and put some rebar or welded wire in it. |

Athens, Ga | We are putting up a 10,000 gal flush tank on dairy. Engineer called for 4- 18" diameter footing 30"(IIRC) deep and 1' thick concrete with rebar on a 16'x16' pad.. I know it's extreme overkill but I'd rather pour alittle extra than deal with a bigger problem later.

NW Iowa | id go real close to exit 12" thick with rebar on 2' centers!! |

Kingston,Mi | Trent has the key to any successful construction, adequate preparation of the subgrade and adequate bearing strength of the soil. Http://www.concretenetwork.com/concrete/footing-fundementals/why_so... has presumed bearing strengths used in building codes.
I have several sites with 36,000 gallon tanks sitting on 60 mil hdpe over prepared soil subgrades with no concrete at all. Many posts on this forum have insinuated that NRCS and other government agencies (and private engineering firms) of over designing every practice ever requested and when the design agency says that the engineering has proven that "x" is adequate, many "experts" want it doubled or tripled. |

Concrete thickness for 12,000 upright tank.
