I live in NJ(Below Freezing in the winter) and I'd like to know if it is necessary to include an expansion joint around the coping on a gunnite pool if the decking is done with pavers.

I have just completed a gunnite pool project and hired my own mason to do the paver decking. Although the contract stated that I am required to include a 1/2" expansion joint outside the coping, my mason said that is only if you are doing cement decking and pavers do not require it so that is how I proceeded.

Then the warranty guy from the pool company shows up and tells me they should have used an expansion joint since the back of the coping(standard 4" X 12" bullnose) will probably chip.

Anyone with experience in this are let me know your thoughts. It's probably a 1 day project to put it after the fact now, but I'll do it if it is necessary.


Thank you.
