Looking for a little insight from more experienced fellers than myself. Due to a number of different reasons, we need to pour footings on a new 10,000 sq ft home if not this week, then next. We're in the Kansas City area, so it's not exactly the weather I prefer for concrete. We dug the footings a couple weeks ago, there was 6" of frost. Right after we dug, we covered everything really well with concrete blankets, then got a little snow on them. Then we got some below zero temps. I haven't checked just yet to see, but will the blankets keep frost out of the ground? We haven't formed anything yet, so the blankets are tight against the ground, well beyond where we dug. We've got some more cold weather this week and we need to get formed. Our footing will be 16" deep and 36" wide, so we'll form one section at a time and cover it again, but will we need to blow heat in there to keep the ground warm before we pour? I've always managed to keep all my concrete work in decent weather, so this cold weather stuff is a little new to me, and there's no way I'm willing to compromise this. It will be done right or not at all. Some more experienced insight will be appreciated. Thanks in advance.
