I found some air pockets next to the pool shell (see pic), and wonder if anyone else has had to deal with this and what steps were taken..
I noticed some of the pavers were sinking a little and decided to re-level them. As I pulled up the pavers closest to the pool, I discovered some pockets. The one on the right side is only about 4" deep, but the one on the left is 12" deep.
This pool is four years old and was installed along with a major renovation to the house. I didn't notice any paver sinking until this year, and thought it might be associated with some severe rainfall we have had here in N. FL in the past few months. I do not think I have a leak from the pool.
