Superglue and sand/rubble

[kilnakorr]

There are a lot of threads on glue, cement, rods etc. on the forum.
I'm wondering if anyone has used ONLY superglue (cyanoacrylate) with sand / rubble and how it holds long term?

It bonds very well, but does it work after some years submerged?

I have never seen it work well. Best to a hot glue as it has more body to it.

I would think hot glue wouldn't bond very well.

The superglue/sand is really sturdy on land.
I had a small accident, and a few pieces broke - the rock, not the glued parts.

When dry, it's obviously stronger than the rock itself, but what happens after a few years submerged?
