We are FINALLY getting ready to install our 25.5x13 Splash pool. We are going to excavate 1-2 feet of soil to get the height at the desired place & get a level ground. We were thinking of adding sand on top of the soil but have seen posts about using foam board. Is this done instead of sand? We will be putting down a tarp as recommended by the manufacturer. Just some background in case you aren't familiar with Splash, they are soft sided pools that don't require the berm around the bottom. In case it affects your answers, we live in Central Iowa & will leave it up year round with a deck built fully around it so visual isn't a concern.
We're digging into Saturday so I need to firm up my plans quickly.
