While working on the back side of my pool today, I noticed that one area of the wall is bulging out making a wave pattern in the plastic channel. How concerned about this should I be? I see no other sections that look this way (although half the pool has backfill which covers up to this level anyway so it's hard to say for sure). The wall is level within 1/8th of an inch all around, nothing is sinking as far as I can tell.
Here are some pictures. It's hard to really see in the pictures, I think, but the wall seems to be bulged out as much as a quarter inch a couple inches above the channel, if you look straight down the wall you can't see the channel wall, just the base. If that makes sense. Is this wall failing?
