My new fiberglass pool was installed last week, and I was wondering how long I should wait to pour my pool deck. I will be using Vastec's coping to pour the concrete right to the edge of the pool. I have heard varying opinions from 2 weeks to a year and everything in between. Pool was backfilled with pea-gravel and sand mixture, and compacted down as they got closer to the top. I really don't want the concrete to crack. Any ideas or suggestions are appreciated.
