So, I'm prepping my ground for an Intex 22' x 52" pool and have the leveling just about finished. Next up is to put in some foam padding. I see that extruded foam padding is the recommended type to use. My problem is that I'm not able to find any locally. Neither Home Depot or Lowes carry it locally and won't ship it. Not sure why. Is there another option? Or, does anyone from the Los Angeles/North Orange County area know of any places that sell it locally? I've looked online and called several local stores, but no luck so far (other than 1"x2'x2' at Home Depot which would take a whole lot of work to tape together).
