Some cracks have developed around the ladder holes and I am unable to get it to go in. I swear the cracks were not there last year, but I can't be 100 percent certain. The pool guy said they had to use a jack to get it out when they closed the pool last fall. The ladder arms are a little out of shape but not to the point that it seems like they wouldn't go in. He said he would try a new ladder and if that doesn't work, the concrete will have to be cut out and new holes put in place. Thoughts? Edit: I just saw that there are some grass blades in the bottom right of the pic, those aren't cracks but they kind of look like it.
