Suspended concrete floor load capacity?

[ollysfollys]

I was wondering the thoughts on if a suspended concrete floor in a 50 year old Ex council house would take the weight of a water tank sat as in the pathetic pic i have drawn below, it will weigh around 2500kg, so around 1 1/2 pallet of bricks, sat right up to the three walls. the footing go down a good 4 foot.
Tank dimensions are 9x3x3.5 feet

Is it a suspended concrete floor? - unusual unless it is a flat.
If it is, the depth of the footings is irrelevant.

What matters is the thickness and condition of the concrete, and the state of any reinforcement in it,
all of which are unknowns.

Keep the mop and bucket handy.

Hi tony, yes it is a suspended concrete floor in a semi house. the concrete is a 6 inch thick, not a clue on the reinforcement though, i do remeber there was also two RSJ under the floor, which i thought strange, but hen i am not a floor expert. I was thinking the best support on the floor for the tank would be mainly around the edge so more force down close to the edge/footings.

Thought i would go on an adventure to the center of our house. Wish I never...I think. These are picks of uder the floor

Doesn't look like it would be a disaster if it failed. Are any third parties affected? Is that the party wall? are you prepared to accept liability for it going wrong? If so, just get on with it. If not, find someone you can pay to take responsibility

Hi, thanks for the reply, yes it is a party wall. So you are saying that the three walls/footing the walls go down to will not take the extra weight. Infact the tank will be sat on all four walls footings, the wall under the kitchen in th epics where the beams are is not the lower party wall but another under the floor.
We are insured fi that cover water damage i dont know and i will take liability of course.

Sounds like you're set then.. Do it because your area is well supported, won't wreck the neighbouring house if it fails and you're happy to do the work and accept responsibility for doing anything wrong, what's not to love? :
