New slab poured...have some questions

[Rainking]

Had my slab poured Friday. I've noticed that is not perfectly even. I sprayed water on it and water pooled in the lower spots. Is this within tolerance or is this not acceptable? I can already imagine pulling our cars in with snow and water pooling there. Anything that can be done now?

No such thing as a perfectly level floor. Your's looks really good. Nothing to be bothered about.

Looks OK to me.

If snow/ice melting off cars was a concern, you should have had a drain installed with a slight slope(s) to the drain.

Looks to be properly pitched. If so, that's quite a bird bath just inside the door. Kinda short of the height of the forms. I think they short poured that and had a bit of trouble screeding.

I've never seen that clean of forms after the placing of the concrete.

Thanks guys. I had a feeling it was acceptable but wanted other opinions. They're also cutting the expansion joints on Monday. 3 days after it was poured. I thought those are done relatively soon after the pour.

If you are concerned about salt and water on the floor from melting snow and ice, you may want to look into these:

This slab looks perfect like pitch or If snow or ice put out cars was a concern, you should have had a drain installed with a slight slope to the town area. Otherwise you want to change something then use concrete and water melt slab then water is not stopped in any area.

I don't know how people are saying the pitch looks ok/perfect from a picture. Was the floor poured level or with a pitch? International building code calls for the floor to be pitched if used for parking vehicles and that's what's enforced where I live. I'd think in NY the building code would be the same.

I don't understand it either, unless the OP really wanted a level floor that wouldn't shed water for some reason. In a slab that size, we would always put a curb on it, as well as 3.5" of pitch to the overhead doors. As long as you screed and float it decent, the "duck ponds" should never be that deep on a pitched floor. That said, for a level floor, the "duck ponds" aren't the worst I've seen......

Oh yeah, the control joints should go in within 24 hours of placement, sooner is better. Weather can change that timeline in the real world, but with the equipment that's available today, there's no good reason to wait 3 days........
