About to replace the bottom before installing a liner in my inground 16x32.
is foam insulation (that you would buy at HD/lowes) a better plan than fixing my sand bottom? or is it more hassle than its worth?
I do already have the load of mason sand sitting in my driveway. it was $100 bucks
one last thing, i cannot confirm this was the cause of my uneven sand but ground water in my area is a problem, the sand under my first liner got messed up and very uneven... if foam would be better, maybe even just in the shallow end.....
