Poured In Place Coping Cracks

Hello Guys,
I want to start by first saying thank you for this forum, it has made maintaining my new pool extremely easy! Here is my question, I had a pool built last year and had several issues with both the poured in place coping and decking. When the coping was poured, forms were set up in the morning and concrete pour continued into the afternoon (windy and 100 plus by the time the sub contractor started to finish the concrete). We ended up with 14 sections that were cracked outside of the control joints (shrinkage cracks), this was mixed on site. Our decking which was a separate pour also had numerous issues and the pool builder sent out the sub back in August to address the issues with the decking. Long story short, the sub has finally agreed to replace the decking along with the sections of poured in place concrete that are cracked. My question is mainly for the coping, is it possible to replace the sections of coping without creating more damage and is it possible to form up the replaced sections to match the surrounding sections, not worried about the color being a spot on match, going to eventually stain and seal all the coping. The sub contractor says he can do it but I would like to get some feedback from anyone who has experience this or done this on a completed pool. The bond beam was floated with mortar and plastic was put on top of the beam prior to pouring the concrete. Thanks in advance and Im going to try and get some pictures uploaded.

14 of 20? If so, I would replace them all. 14 of 50? Then I'd try just replacing those 14. It's sad that these guys are so incompetent but the days of quality work are a memory. I have a couple of identical stress cracks in my poured coping (the coping wasn't properly cut from the decking) and I'm just going to live with them - sometimes the cure is worse than the flaw!
 
we need pics from farther back to see what is rly going on. yes it is possible to repair the coping and have it look good, chances are on a re-do they will rush to get outta there. maybe throw them some cash ahead of time and ask nicely to have a good job done. If its that hot out they should have a truck deliver redi-mix. you can control the drying instead of worrying about mixing and overmixing the material, and its usually cheaper even w a short load charge.
 
Ok guys, here are a few more pictures of two cracks. Picture one and two are of the one crack and pictures three and four are of a second crack. Theres more than just these two but I'd really like to see if anyone has had any personal experience with removing sections of poured in place concrete and replacing them and how it turned out. The subcontractor has agreed to remove/replace decking and cracked sections of coping.

when you pour the concrete like you have its a pattern, they tool the pieces to look like individual blocks and coping but they are all tied together. Somewhere in there you need control joints so the concrete will crack at that joint and not somewhere else (it will crack eventually) when you cut a piece out and replace its not monolithic in the same pour so even though its tight fitting it will look "placed"compared to the pieces all around it. concrete filler is used to blend the pieces together, and that final touch can make or break a repair like this with how its applied and smoothed out
 
Good morning everyone, I just wanted to give my post a quick bump. I have the subcontractor coming out on Wednesday to tear out the decking and possibly the the cracked sections of coping. Is there anyone here who has had sections of poured in place coping removed and then replaced and if so could you please post some pictures and your thoughts. I'm actually leaning towards just staining it and sealing it to "hide" and fill the cracks, so if any of you have gone this route I'd really like to hear your take on this also. Thanks again everyone
 
I had some coping cut and replaced, but it's the coping around the fire pit and not the pool itself.

The toughest part was that the "keys hadn't even been handed over yet and the car already had a scratch on it". My builder made a good faith effort to correct my fire pit coping and I'm satisfied with how it turned out though it's not exact in texture due to being a hand mix. It's a tan color mix with an acid wash finish. You can see the end result below.

I've since developed a couple of hairlines on the spa coping but they are faint and not worth messing with imo.

You're tearing out all the decking, but not all of the coping? You can't patch the cracks - the cracks will reappear in no time, and its almost impossible to "hide" them as they will get bigger with time (and chip/crack at the top, if you live in a freeze area)..

Thank you so much, this is what I was looking for. Do you mind if I pm you a few more questions?

Believe me, I'd love to have all of the coping removed and replaced. I wanted this done prior to the pool being completed however the builder refused. It wasn't till we started having issues with the decking that I contacted the subcontractor and almost a year later, I've finally got him to agree to to make the repairs And is willing to replace all of the decking but only the cracked sections of the coping. My biggest worry is them creating more problems when they cut out the cracked sections which is why I was thinking of maybe just doing an acid stain and seal it.
 
Just an update, contractor came out yesterday and removed all decking and cracked sections of coping. So happy to say that not a single tile was damaged. My question now is because there are so many sections removed, I'm now leaning towards replacing with pavers or stone. Would the pool need to be drained to install pavers or other coping options that would use a mortar base? Thanks guys for the help
 
you would only have to draw the pool water lower IF the tile line would have too big of a gap with a bullnose paver or similar, and then add a tile slice to fill the gap or grout/caulk it if its acceptable. your other issue is the base for pavers/stones is different than concrete. they would have to remove at least 5" of material and put a 4" minimum packed base and then a 1" max screed bed of concrete sand to lay the pavers. they could also pour another concrete slab lower and mortar the pavers to that slab. either way its more than just replacing the concrete with something else, the prep is totally different. regardless I hope you come out OK in the end, it sucks that you even had to deal with this. If you do concrete again make sure they protect their work from the elements and the sun this time
