Hey, found out that the areas that I thought were 4 old low spots from install are new from critters under pool (best guess - chipmonks). The areas below them feel like there is no support. Like they tried to come up and hit the liner. Felt in the bottom of the holes and 3 feel like there is still open area below. Didn't want to push too hard. The liner has lost its color in the holes. There was still stretch left in the liner.
What I need to know is, if I can just put patches above the circles now? Going to be 90s rest of week and water hopefully will be warm enough to get in and fix before winter.
Are there heavy gauge patches? Can I just run over the hole flat? Will the glue hold up if the water drains if the liner gives way below?
