We have had our pool for about a year. We’ve had off and on concerns about the whole process. To make matters worse half of our pool is not completely inground. We noticed cracks on the outside with calcium build it up. Sure enough the crack carried all the way through to the other side. Upon further inspection we noticed at least two more. We finally had to put our foot down and tell the pool company owner that we don’t think it’s normal at this point and we want something done. Finally he said they will drain it and go from there. Sure enough they cut out 17 cracks and at least 12 more need to be cut out!! We just want it done right and we no longer trust this company to do what is right but we don’t want to fork out money on this! We’ve requested an engineer. So we are waiting for that before the press forward. Has anyone had experience with this? Is it structural or is it indeed “normal or an easy fix” as our pool company says it is?
