I bought the house with a pool last year. All what I know is that the pool has been in place for more than 10 years. Around the pool, the pavers (bricks) got sink down a little bit at some areas. I posted several pictures to show them. It is definitely not getting worse from what I saw last year. However, after searching online, people are saying this may cause inside skimmer cracks. I did find some cracks inside the skimmer and fixed them yesterday with A+B epoxy putty. (Hope it can fix the slow leaking issue I had, around 250G/day.) So can anyone let me know what cause the paver sinks, and is this a big issue or potentially a big issue? How to fix it then?
thank you very much.
