above ground pool base
I need to replace my onground pool liner. I currently have styrofoam as a
base ( I prefer it to using sand) but was thinking of using something denser, something that will compact less. Perhaps polystyrene insulation. Anyone used this? Which thickness would you recommend? |

Which thickness would you recommend? What form is the Styrofoam in now? Bead form? Insulating sheets can take a fair amount of pressure. Most expanded polystyrene insulation is 1 pound per cubic foot or less. I know that 2 pound will deflect 5% at 23 psi. It would give a smooth base. I'd probably tape over the seams so there is no pinching. Is it a good idea? I have no idea as to how practical it is. I think that will also depend on how smooth the base is so you get a smooth bottom and not a bunch of 2' x 4' panels at odd angles to each other. |

I think I will go to 4x8 x 1" polystyrene insulation ductaped together. |

It is available at many building supplies places. Bob |
