In the process of cutting and jack hammering a concrete slab to facilitate relocating a toilet, we hit the existing no-hub cast iron drain line. I patched it with JB Weld FiberWeld, which is basically fiberglass and epoxy. I was quite pleased with the result and thought I would share. I think this FiberWeld is the same material that is used to line failing cast iron pipes. It is airtight, water tight, and mechanically solid.
Attached are before and after photos. The patch is not super neat, because it's a bit hard to work with the fiber with sticky resin. But nobody's going to notice with 4" of concrete on it.
