Sourcing a large repair band
We have a 30 inch concrete asbestos pipe that runs over land and crosses a creek. It was recently damaged by a fallen tree. It knocked a hole in the top of it. It's gravity flow line so no real pressure to consider.
We use alot of ford repair bands for water main repairs . They are extremely robust and expensive 5k.
Anyone have recommendations on fix

Guessing you’ve ruled out duct tape?

Would need to hold up to the elements

Gorilla tape might work actually…. But I like the epoxy idea our friend mentioned.

Yes! You can link repair clamps together to make one much larger clamp. It’s trial and error to get the right size. If they are the same brand they will generally hook together. You can do the math for the circumference and get pretty close. I’ve use this method a couple of times. Be warned however that there were several classes of AC pipe. Some are extremely brittle and over tightening will lead to cracking. My experience has been to tighten it just barely enough to seat and then maybe a couple of more turns.
The stainless bands will help stabilize the pipe and the rubber will seal.

Hydratite may have a solution. They have what I would describe as an inside out fernco. There's a rubber lining that is held in place with bands from the inside.
Your situation may be way too far gone for that.

We have a 48” primary effluent gravity flow line that was corroded pretty bad. They used fiberglass strips and a thick clear epoxy and wrapped the pipe 360 for about 6-7’ in length. Its been a few years with zero issues.
