Hi all- I’m getting ready to pour my concrete bond beam around the pool as a base for concrete paver coping (18x36 polymer wall vinyl pool). I’m building out the forms for a 4” deep concrete beam. What are the recommendations for pouring the concrete around the skimmer? I’m thinking I want to box it out to provide an air gap between the concrete and plastic of the skimmer. Should it use a joint expansion material as a buffer? Thanks for any advice!
