I'd be more up for the industrial coating vs. a 2" cap. Seems like a thin cap like that would just be asking for trouble down the road. I'm thinking along those same lines. Sure they hope they get it done right.
Sounds like maybe some calcium might have been in the mix. Causes a fast set and brother does it get hot. It was literally "hot" while it was curing. Winter mix. No expert, but sounds like what I've heard of used in cold weather pours so it cures before it freezes.

Experienced or not, don't let them give you the "hot mix" bullschitt. They didn't get a hot mix, they were too slow for the size of the pour. They needed more labor.
It happened to me last fall on a train station project. Not enough labor and they lost the mix.
I'm very glad they're working with you on it!!!

I think you are right, Tom.
It got them by surprise, the insulated mold they poured this in really amped up the cure once it started to kick.
No place for the heat to dissipate to, and all the moisture only had one direction to go, up.
But even still, this wasn't their first pour in a foam liner.
Something clever here.

That thick edge holds A LOT of heat and it will for quite awhile. That slab will cure for about 28 days. The heat is what makes it get hard. We can pour a bridge in November and cover it with insulated blankets, and at 20*F, the conc will still be 80*F.
A lot of times a big slab will be poured in sections, usually as long/wide as the screed. But doing it that way requires a lot of laborers and finishers.

Is it more of a cosmetic thing, or is it structural. Sounds more cosmetic. That being said, you sure as heck didn't pay that much money to have it look bad. Clyde

Cosmetic as far as I can tell.

This could qualify as your first restoration project! Too soon? Okay. Not nice. My apologies.

That's fine, CFT. Someone has to try to help keep it light, I don't mind.

As a fellow business owner, this is just a speed bump along the road. There will be more. You've got that entrepreneurial spirit that made 'merica great! I'm sure it's that burning desire to get going that makes these kinds of delays so frustrating. As they say in that Wag the Dog movie, "This is nothing!" A ways down the road you're just gonna laugh at this one.

Been following this all along and I'm another in the "envious" camp. You have a dream project there. I know it will all come together.
Best wishes for a great future!

Think of it this way, if you get the surface coated with epoxy on the contractors dime, it is a win for you in the long run. It just makes the run take a little longer.

Bingo! And this ^^^^ I doubt you could an engineer to sign off on a 2" cap anyway, and I'd dam sure want one before I'd even consider it. Epoxy and keep rolling at this point. Luck

Maybe all the dead bodies you were hiding in the slab contributed to the problem?
What you do today is important, you are trading a day in the rest of your life for it.

2 inch cap with some sort of super bonding agent.
The solution came from Lafarge.
I discussed it with tzone over the phone this morning. (some details of the plan)
It is what it is.
I guess I'll roll with it.
I have to get to work in this shop, it needs to get built.

I have pictures of this surface issue for the concrete, just can't bring myself to post them.
It's not the whole slab mind you, very far from it. I don't know if the effected surface defect totals more than 1 % of the 3000 sq ft pour.
But even at 1%..... where do want your 30 sq feet of ugly in your new slab?
Nowhere.
We'll work through it.
That just sucks, sorry that happened.

I contacted the concrete company today. Explained that I needed something in print from Lafarge indicating that they stand behind this process, also asked for an engineer to sign off on it.
I hate to be a dick, but this is kind of important, it's not a sidewalk.

If you don't look out for your business, no one else will. That kind of fortitude is going to make your business a success. Curious, will the 2" inch cap have any affect on heating the building? It would seem the system would have that much harder.

the heating is one thing that concerns me too dave, now having to go through another layer basically more concrete. i hope it will still sinc through the extra layer and not take as long to keep it constant. the heating cooling process of the system could be challenged. I hope they can get you going soon. Time to start framing!
