Using Foam Insulation Board for a Pool Floor
I'm in the process of designing my inground vinyl pool and just checked-out a friend's vinyl pool. Instead of using vermiculite for the base, he used 2" blue foam insulation board. It's definitely a softer bottom (real similar to a sand bottom) and you can feel the uneveness of the dirt below it. I was wondering if anyone has heard of using this before (pros & cons), it's alot cheaper than the vermiculite and would be easier to install.
