My current project is in Alaska. It was 15 below this morning. They are getting ready to shut down for the "winter" when it turns real cold.
You might want to consider expanded shale. It can also be used as a structural fill. It is very light weight.
Before I would do anything, I would find out if the soil is subject to frost heave. If it is a gravel, you may not have to do anything. Talk to the geotech.

I've got a small commercial project that's getting put on hold, just before the Wyoming winter sets in. I'm sure I'm not the only one. This one has footings & concrete walls, but no slab, backfill, or floor package, and the owner doesn't want to (can't?)do anything else, except the bare minimum to protect his investment from frost. The outside backfill to frost depth is no problem, but those footings are exposed on the inside, too, as well as lots of interior footings, elevator pit, etc. The footprint is about 4,400sf. Filling it up with 500 cu. yds of dirt (to frost depth) and then scooping it out in the spring seems too painful. Does anyone have good ideas for reasonably priced blankets or even lightweight structural fill?
thanks,
Gordon Goodell
