I just purchased a 16x48 Intex pool. My question is which like the title says I am probably way over thinking this, on a 16' pool it has 8' radius I need to go out an extra foot, I am going to be using foam under the pool do I go out with the foam over the pavers or all the way out to the whole radius that I leveled out. Please forgive my ignorance I tend to over think stuff.
