Hi we are in the middle of our pool build and our rectangle pool on the shallow end was not built straight, see pictures. This means there is a large gap when the cover closes.. the builder is trying to suggest ways to fix so the cover performs as intended (so closing the gap) but the ideas have been terrible (like insert a piece of decking in the end of the pool - which would of course look terrible) has anyone fixed this, what should we say to the builder ?
