I have a 30x15 foot above ground pool. We have a section that has dropped about 1-2.5 inches due to a chipmunk tunneling under the pool. I think I've solved the chipmunk issue, but now I would like to fix the pool. The liner does not seem to distressed over the depressions. But cosmetically "we" (my wife) would like it fixed.
My current crazy thought is to attached a long tube on a can of high expansion sprayfoam, and fill the void with foam. I'd have my wife stand on the pool and use her foot to try and level the application. The pool is only 52" deep, so my math says there is only 2 PSI on the floor of the pool. Which the spray foam should be able to overcome. I might end up with too much foam pushing the liner up, so I'd go slow and see what happens. My biggest concern is compatibility of the spray foam to the liner. Spray foam is used with vinyl windows, so... I think there shouldn't be an issue, but I wanted a sanity check before a burn a big hole in my pool.... Even if I can just stabilize what is there, it would probably be OK.
I did a form search, and I all I found was solutions to drain the pool. I apologize if I missed similar solution.
Thoughts, comments, am I totally insane? Has anyone tried something similar on the forum?
