I assume you have thin saw cuts. No, they don't get sealed with caulk normally.

A little bit of crud may get in the pool. If it gets stuck in the cut, a Popsicle stick will usually pry it out.

I doubt anyone will get pinched.

Thanks Pool guy, The stone and tile are now in and I'm getting used to the look. I like it. We are now looking at having either pebble sheen, or another off brand mini pebble but in. I'm not into making the creative decisions here, I leave that to my wife. I just want to make sure it is done right, and I'm learning on the fly what right is.

I am in the finally stages of my pool and I have noticed a ton of hair line cracks all around the poured in place concrete coping. I do not like the look, obviously, but am afraid with time and water seeping in cracks it will deteriorate. Is this acceptable with a new pool and what should I tell the PB? Also the stamp concrete has two very long cracks right by the cut lines. Please advise as I still have a small outstanding balance and want it to be right.
Thanks

All concrete cracks and no one guarantees it from cracking. There are however many things that you can do to control and eliminate cracks.

One thing with poured in place coping is you have to cut control joints every two feet minimum.

Pictures would be helpful to see the extent of the cracks and workmanship.

And we had pour in place coping done two weeks ago and already have cracks even with expansion joints ..this should not happen should It ? I want them to replace it just don’t know what kind of mess that’s going to make we haven’t even been able to use the pool yet as the pebble Tec just got done a week ago

There are many reasons concrete cracks. The most common when it cracks quickly is shrinkage cracks which means water left to quickly as it was curing or they let it get to hot sitting in the truck and added water which then surpassed the minimum water to cement ratio of 4.5.

They could have also waited to long to install the control joints.

Depending how many cracks you have will merit wether you have a case to have him reinstall it,
