Deck/collar question on new fiberglass pool

[JPontius6]

I’m almost ready to pour the deck around my new fiberglass pool and I’m wondering about the concrete collar and deck. Do I need to pour them separately or can they be poured at once? Also, rebar/remesh vs just fiber reinforced?

Thanks!

From what I have read a cantilevered deck can form the concrete collar. Just have to have a concrete guy who knows how to do cantilevered decks.

Why is Pouring Concrete Coping Around a Fiberglass Pool so Difficult?

One of the biggest difficulties of installing a fiberglass pool is proper cantilever coping, which, when installed improperly, can be a disaster.

Thanks for your response. We're actually using an aluminum bullnose coping that is part of the autocover track (from APC), like this:


With this coping, there shouldn't be any specific skill required to pour, screed, and finish the concrete to the top of the coping. I'm leaning toward drilling into the pool lip to place fiberglass composite rebar like this going horizontally outward from the pool walls (suspended in the middle of the slab). I'd then pour the collar and deck slab all in one pour with fiber-reinforced concrete. My main concern with this plan would be the amount of inward pressure the collar and slab might put on the pool walls. Obviously I need to keep them from deforming during the pour. Thoughts?

@bdavis466 @MinerJason @Rich D may have some thoughts on the pour.
