So we drove by the house last night. The forms are all in, but they haven't yet poured the concrete.
I sincerely hope that they they either pour today or wait until Monday next week. Today it's supposed to be nice, -9C, tomorrow even better -3C. Friday/Sat are slightly colder -10C but back up to warm on Sunday -2C.
I think honestly it will get poured today. Ideally you want at least a day or so of warmer temps, but regardless they will be pumping in heat, so that's good. It's all very nerve wracking.
But I'm fine. Really just fine. No problems.... not nervous at all...
