Good afternoon everyone.
New to the community here... Bought a home with an inground pool this time last year that had the original liner (12 yr old) still intact. Pool was not leaking with the old liner but was beginning to tear around the beadlock so we purchased a new liner.
June 1 of 2019 a local company removed the old liner and replaced with a new liner in the same day. I was not present at the time of the replacement so I can not speak on the condition of the side walls and vermiculite bottom. We continued filling the pool with well water for about 5 days before it was completely full (didn't want to go full blast on the well for fear of burning out the pump, or removing too much water too quickly from the reservoir)... Had no issues with the liner all summer until early September 10th when a depression, 1-2 feet long X 1-2 feet wide x 2-4 inches deep, began to form under the liner on the transition from shallow to deep, right against the downslope from the side wall. The company charged me $400 to come out, drain the water to the depression, pull the liner back from the side wall, place a mixture of vermiculite/sand in the depression, "tamp" it down by stepping on the liner, and reseating the liner. This took about 1-2 hours, mainly the time to drain it. About 3 weeks later in early October, the depression came back. The company said "they'll address it in the spring". Spring is now here and they want to charge me again to do the work. Another local family owned company spoke with me over the phone for 10 minutes and told me how to do the repair. I am going to attempt the repair myself by draining it down past the depression, pulling back the liner, try to dig around/remove any soil to determine WHY this has happened twice and then fill in the depression with some sort of concrete. The questions I have are as follows:
WHY this is happening - hoping to gain some insight when I do the repair.
Can I put quikrete in the depression or another time of rigid ready mix concrete - something sturdier that vermiculite? If I put concrete in the hole I have a couple pieces of liner that were left over from the liner replacement and will place the liner piece in between the liner and the concrete to minimize friction or any sharp edges from the concrete. I plan on digging wider than the depression and filling with concrete.
The depression is cosmetic but also has a sharp edge that could tear the liner. I know there is risk with pulling back the liner with it being 1 year old - What do you think my chances of tearing the liner are? Again the depression is close to the sidewall so ideally I could remove the beadlock, and be able to access the depression straight down, without crawling underneath the liner.
The pool is holding water, I have not noticed a leak in the slightest so I don't think one of the return lines is leaking. I do have a large Oak Tree about 50-75 feet away from the edge of the pool that may have old roots that rotted? The depression is about 4-5ft below the earth though.
Overall thoughts on pursuing the repair myself?
