Crew forgot the vapor barrier, caught it 3 hours in
We were pouring a 40x60 slab outside Omaha Tuesday and the foreman never laid the poly under the rebar. I noticed the ground looked wet where it shouldn't, asked him about it, and he said we'd just burn it in after. That's how you get a slab that sweats for years. We stopped the pump, pulled the pour, and redid the whole base with 6 mil sheeting before any mud hit. Cost us a full day and $800 in standby fees. Has anyone else caught a missing barrier mid-pour, or do you walk the site first thing every time now?

Last spring I caught the same thing on a 30x50 shop slab in Lincoln, the crew had the rebar up on chairs and the vapor barrier sitting rolled up by the trailer. I walked the site before the pump even showed up, which is the only reason we caught it. Now I check the poly on every single pour, even if it means getting there an hour early with a flashlight. You did the right thing stopping the pump, that $800 is nothing compared to a floor that bleeds moisture for years and ruins whatever coating or epoxy the owner puts down. How long did it take you to get the crew back on board after the redo?
