I am replacing an 18' above ground pool (circular) and i removed all the sand already. I also bought a gorilla pad. In addition i was thinking of buying the hard plastic foam sheets (mainly for insulation a for the bottom of the pool).
Worth noting is that the sand has some small pebbles (i am filtering it thru 1/4 mesh to remove any larger stones). The sand is mostly pure... The pebbles are simply due to having to dig it out from the old pool (slight ground scrapings).
Question One (assuming no floor foam):
I am wondering if i am supposed to put the sand down on the ground and then the gorilla pad above the tamped down sand? Or would i put the gorilla pad down first and the sand on top of the gorilla pad?
Question Two: if using floor foam i would assume the order would be: floor foam, sand, then gorilla pad. Is that correct?
Question Three: does the floor foam really work well as an insulator? Is it worth the trouble and expense of adding it?
(btw, i plan to use wall foam and foam coving as well... In case that makes a difference to the above questions)
Ahead of schedule (yay!) So I might be at the point to start laying the floor today, so hopefully some can throw me a reply soon.
As always thanks in advance for any recommendations,
