I’m rebuilding a damaged wood wall pool. Bottom was sand. The wall structure Repairs are finished and now we’re digging out the bottom. I’m planning to do a grout bottom but I liked the soft feel of the sand we had. Can I put 1/8” wall foam over the grout bottom before the liner goes in?

I don’t think we’ll be ready for the liner for a few weeks yet. We can only work on the pool a few hours a week. Yesterday we dug a sump pit to get rid of ground water in the deep end.
