Hey guys I had a 15x48 intex metal frame. It had 1inch of sand on the bottom the wasn't that smooth. The next door kids throw big rocks and bricks over the fence and split the liner. 4400 gal of water came rushing out in the street. The next door neighbor had to buy me a brand new one. So now I'm going with a foam board bottom. I have 1" 4x8 Extruded Polystyrene sheets from lowes to put down. I have a budget to work with. The 2" is to much for the budget. Duct tape then put a hd trap on top of the foam. Is that ok to put under the pool? Also can I put pavers/bricks under the legs or will it put a hole in the liner?
