Have question on tank weight and basement floor

[JazzMan]

I am looking at installing a 120x48x30 tank in the basement of a new home. Does anyone know if the slab in the basement will have issue supporting the weight of a 750 gallon tank? I don't know the thickness of the slab (have a call out to the builder), but I am wondering if I should be concerned.

Thanks.

I wouldn't be concerned since you said it's a new home(should have at leat a 6" slab).

Figure that's about 35lbs/sq In. then add in the weight of your rock, sand and equipment.

A standard 6" slab is rated to support upto 306lbs/sq in.

+1 a slab is the perfect place for a tank that size. Don't forget to post build pics, you spilled the beans, its your fault! lol congrats on the new tank.

You want to check with your builder as a 6 inch slab is not all that common. Or regardless of the specs saying 6in of concrete you may end up with fill that is 2 or 3 inches higher than spec, and only 3 or 4 inches of concrete. I would make it clear how important the slab thickness is to your builder, and if possible go out to the job site and measure the slab thinkness they have allowed before it is poured.

I built a new home a few years ago and the code for the slab was 3000 pounds per sq inch.... Don't know what your code standards are but you can get them right off the building plans.

Another thing to consider is how well was the subgrade compacted prior to pouring the slab, often times this is neglected in housing construction and could present settlement issues once you add the aquarium loads.

you should be ok, a standard basement pour is 4". I have seen some that were less BUT they were pulled out and repoured!
I agree with ryandlf congrats and get some pics!
