Do you know what cause it? Do I need to take it seriously?

hi,

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.

I can't say for sure... but my guess would be that some of that 250gallons per day that you are leaking is eroding the ground underneath the pavers, causing them to settle... I'd guess there is more to it than the skimmer cracks you just filled.

If you are leaking 250 gallons per day from the skimmers, instead of filling up, let the water drain. Then if you have a main drain, bring the water below the skimmers. As you mentioned previously, you used an epoxy to seal the skimmers. Carefully (because the skimmers are now dry), epoxy any other areas and maybe add a second coat over the previous cracks. If you have pavers that have sunk in the ground around the skimmers, take them out and fill the area up with "concrete dust" or some similar material. I would recommend going to a concrete specialists as they will have what you need. Once you fill in the area, tamper down the fill and place the pavers back.

As Joshjv stated, you may be losing soil to erosion. With the right materials, this job should not take you too long. If you are not comfortable, after sealing the skimmers with the epoxy, you can call in a mason. Should not be too much trouble.
