Pour in Place Coping with Existing Deck

[Geophffrey]

I'm looking at pour in place concrete cantilever coping to hopefully hold up longer over time than natural stone (lueder limestone) did with my SWG. I'd prefer no joint between the decking and coping and no joints in the coping, to give the appearance of a single deck that extends into the pool. There will be a plastic joint under the pour in place cantilver coping between the pool shell. Rebar will connect the new "coping" to the existing decking.

I've seen people do this build when they first build their pool, but has anyone replaced their coping in this way after the deck has already been poured?

Conversely, I could do pour in place with joints in the coping and mastic between the decking and coping, but I prefer the look above.

Thank you in advance.

To pour new coping against an existing deck without an expansion joint will be a cold joint and will most likely crack in an uncontrolled way.
You can pour coping without control joints around the pool, just know that it’s going to crack at some point in time and not in an even pattern.
A way to achieve a cleaner look is to have the expansion joint as small as possible, this is determined by how many feet of decking is going to be expanding/contracting.
Your last choice may have the best outcome but not the look you want.

Thank you for the reply. Maybe I keep the expansion joint, color it the same as the decking, and spray deck the new coping to "kind of" achieve what I'm looking for. I was going to use the existing decking joints and extend those into the coping for a more seamless look.

Unless you are lucky precast coping will look much better then poured inplace coping using forms.

I’m doing cantilever and not precast. I was curious about others experiences with cantilever. Do you have any experience with it? SWG has ruined my leuders coping. No doubt about it, despite claims on this site that salt is fine, it is rough on stone in Texas due to freeze thaw. So I’m going with concrete and the wait time for precast is ridiculous.
