how long can a sonotube sit before concrete is poured?
I need to dig 8 footings for my deck, and will be doing this over the course of about a week. I want to pour all the concrete after the holes are dug, and the sonotubes are set. My question is can I set each tube and backfill as I go along (which leaves smaller holes in my yard), or should I wait until right before I pour the concrete? I'm worried about the tubes getting soggy before I can get concrete in them, but at the same it would be easier to protect a small 8" opening rather than the un-backfilled hole.
By the way, weather looks decent for the next week. No inspections. And soil drains pretty well.
