I have a new 30 x 15 steel wall liner inground with the 6 inch radius corners. We are getting stamped concrete coping and deck installed in a couple weeks. Is there a way to get the corners squared off or do i have to follow the curved corner radius of the liner track? A lot of photos i see look to have square corners on liner pools. My mason is saying to follow the radius or you will see a portion of the liner track exposed if he squares it off. Thanks for the help. Mark
