We have a new gunite pool and the waterline is off by 3″ from one side to the other. Is there any way to build up the side of the pool wall to level it out? We have travertine decking so I do not think it would be too difficult to pull up the travertine. Its our first pool and we have spent a mini fortune on it. Not sure if this is able to be done, but its all I stare at and im ready to sell my house. This pool build has been a disaster. thanks for your help!
