Thanks for the info. That would make sense if it wasn't compacted evenly since it's only by the wall. I would ideally still have a paver guy do the work and just see if they can compact the deeper soil. I think that would probably take care of the issue since it hasn't depressed that much in 2 years and the past year we saw a ton of heavy rains.My assumption about the supporting deck was wrong, I assumed your elevated pool deck was a wood structure rather than on-grade. That's why I asked about the design composition of the underlying support structure. On-grade paving failures like yours are often a result of the sub-surface bearing characteristic not achieving the desired and equal density and bearing capacity within the restrained area (it was not mechanically compacted equally). Thats why you are seeing settlement differential between the wall and in the adjacent paver field. In simple terms when they make the repairs, make sure they probe the failed subsurface areas with a steel rod before completing the repairs and compact the soft areas of the sub-base.
Or you could get lucky. Go get a 4 foot level, a screwdriver, rubber hammer and 4 or 5 bags of paver sand at the big box and just pull up those affected pavers, add some leveling sand under them and never have another problem. Simple!
I might just lift up a couple and take a look at what I'm dealing with.
