So it's that time, were finally upgrading to an 18' round AGP. I want to do things right as this pool will be expected to last several seasons. I'm staring with leveling the ground, then will add a crushed limestone base, gorilla pad and then liner. That being said, since the pool is 18' should I make the crushed limestone base 20' to allow a foot of extra space on each side? 22ft? The pool were installing is the hard sided type. How much extra should I make the base?
Thanks.
Thanks.
