I saw some photos on this site of a round above ground that had been buried completely with concrete decking. I just purchased a 28' Sharkline Matrix Resin Salt pool and that is EXACTLY what we would like to do. We are just not sure how to backfill in order for it to support the concrete. I did inbox the user who posted the pics but it appears that he hasn't been back on the website since 2009. I have buried an a/g in the past and after 10 years of use we moved and it was still fine. I used wood last time for decking but would really like to do concrete this time. The liner would still be accessible since you do not have to completely remove the rails on this particular pool in order to change the liner. I would love to hear suggestions from anyone who has done this before or knows someone who has.
