Ive had a cheap 10 foot above ground pool on my patio last couple of years

This year got a cheap 14 foot pool at academy for like 300 bucks
Looks to hold 2,700 gallons, which at 8.3lbs per gallon is over 22,000 pounds

Havent put it up yet- should I have any concerns about that much weight on the patio?

Square feet of pool area?

Divide 22,000 lbs. by square feet.

That will give you pounds per square foot.

I wouldn’t think so….that weight will be spread out over a lot of area. I wouldn’t be concerned unless the pool ww]as 10 feed deep or something like that.

14 feet is from the basketball goal to that chair. I would center the pool across those 2 squares

The concrete pad looks to be 4” deep

id think a 4" could handle with no problems and the concrete looks in good shape.

A simple calculation is that 14 ft pool is 154 sq ft. 154 sq ft is 22,176 sq inches?

22,000lbs/ 22,176 is 0.992 psi?

I'm not an engineer but that seems right?

AVG psi rating for basic concrete is 2500lbs

Its probably at least 3000 psi concrete so the pool would be applying less than 1 psi.

If you will be filling it to the same height, the total weight is irrelevant; it's the weight per sq ft that matters, and at the same height of water, that will be the same.

Edited because I saw answers to my question in the thread
