I have had an above ground pool since 2008. The pool was installed professionally. I have had to replace the liner 3 times, professionally installed as well. We have talked with the pool installer, he recommends sand. I really want to try something else. The sand appears to erode at the same location, causing liner failure.
This will be the last attempt, so we are hoping to create a highly stable surface. The current underlayment is pool sand. However, the liners are continually failing. Current liner is 25 mil thick. I am planning to purchase a 30 mil thick vinyl liner in a week or so. I have read a great deal online about synthetic foam boards/pads. Would you be able to provide some specific guidance? (thickness, etc)
I have also read about gunite. Any suggestions on this? We live in southwestern Pennsylvania.
We do not have grass or weeds near the pool.
