Concrete Pad Under Pool

by Bill

On a 24 ft round above ground pool how big should I poor the concrete pad and how thick? The pool also has a 2 ft walkway all around. We are going this route because we had some mole damage that tore up our liner and we have to replace it.

Hi Bill. Pouring a concrete pad is the best way to get rid of a mole problem. I hope it works for you.

You will need to check with the concrete folks as to the thickness. In the warmer parts of Arizona 4-5 inches would be plenty. I'm not sure that is true everywhere.

The size should be at least a foot larger than the pool all the way around. So a 24 foot pool would need a concrete slab with a 13 foot radius, or 26 foot across.

That is assuming the support posts for the walkway angle back to the pool, as most that I have seen. If they go straight down then you should allow ample amount of concrete to safely set these posts on.
