Plywood Base with Foam

by Bill Martin

I have a 14 x 42 Intex metal frame. I had to do quite a bit of digging to get the ground leveled. I didn't want to use sand because I'm just not sure how much use it will get. Last year I used foam, but the rocks still managed to get through at a few spots. This year I thought of laying down plywood and putting foam sheeting over that as well as an old pool liner. Good idea?

Hi Bill

I see no problem with any of that. I would do the old liner over the plywood and then the foam. Old liners can be a a little tough to get to lay flat, but would provide a nice moisture protection over the plywood, and it would be possible to pull the liner flat and tack it to the plywood.
