seaside Posted June 23, 2007 Report Share Posted June 23, 2007 Hello, We're in the process of installing an endless-type swimming pool on concrete, with deep end. We wanted to know if anyone would recommend (or advise against) rigid foam insulation (such as Celfort 300- 2" thick boards) for the bottom of the pool beneath the liner. Might there be problems with the liner getting between the cracks around the insulation boards and the concrete? Will the foam compress too much and thereby stretch the liner? We wanted to put the 2" boards in the deep-end and 1" thick everywhere else. There's a 250 lb. flow head that would be sitting on the 1" foam at one end. Any help or advice would be greatly appreciated. Thanks kindly. Quote Link to comment Share on other sites More sharing options...
