I guess I didn't realize that rocks and dirt have been covering 2 sections of my wall about 2-3 inches up. The track is resin thankfully but after I dug it out there is 'bubbling' at the bottom of the wall. It's probably been like this for maybe 2-3 seasons. I guess I didn't realize it would cause potential rust issues. Does anyone think the wall is in danger of rusting and or collapsing? How bad is this. My pool is about 7 feet from my house and basement so very concerned about a potential pool wall failure. Any thoughts and opinions would be welcome.....
