foamboard for pool bottom?

[mstriker]

Hi all,

Just notice water level was gone way down in pool went to investigate have big rip in liner. So when I replace the liner I saw some
people use foamboard. I currently have a sand base which overtime of seven years has gotten ruts in. If foamboard is used
my concern would be if any wash out would happen underneath or if the board cracks any thought or suggestions
pool is 24' round 52" high

If cut and taped properly you should never have problems with it. Use the foam cove on top of it and you should be good.

Any suggestions on thickness of board?

Thanks

Most people use ½" but there are threads of people using up to 2". I'd say it's a personal preference.

I have been using 2" foam for about 8-9 yrs now. I learned about it from a friend with a 24' perm. pool, he also has 2". The 2" has better insulating properties and holds up better than any otherthickness. Yes it is 2X the $ but it has been worth it to me.

Thanks for the info. I haven't replaced it yet just waiting for it to get warmer. I was concerned with 1/2 foam because I have steps vs ladder sitting in the pool wasn't sure how it would hold up
