So, my pool is on a slope. Leveled it with a bobcat initially. Pool has been up for 5 years. We have had several really strong storms with heavy rains this summer. Unusual for the area. Anyways, there is a small section that we never back filled. Wasn’t quite sure what to do there and haven’t had any issues. Until now. The pool cove has drifted away from that side several inches, pretty sure our sand underneath is eroding, lots of wrinkles in the liner and now a rip in the lining at the other end of the pool. Pretty sure the robot did that on Friday. Help would be very much appreciated !!! Please and thank you !!! (1) how should i fill in the area that is slightly lower and (2) what do I do with the liner? (3) I think the end of the pool where the rip happened is sinking. My hubby thinks I am seeing things so it must not be too bad if it is happening. Maybe just starting. Attaching a photo. Thanks for your help. The cones are there so the dogs don’t run through there.
