We just had a local internet company bring a fiber line to our house. While they said the line could be buried directly in the ground, I opted to dig a trench and lay 3/4" pvc electrical conduit for extra protection of the cable. It all went very smoothly. The cable goes into our house via an LB junction, and cable goes into the pipe (that is sticking straight up out of the ground) at the closest pole on our property (from which our electric service and phone are also suspended to the pole and then go underground to the house). I plan to use something like spray foam (something weatherproof) at the end of the pipe where the cable goes in to seal it from the elements. I don't want water getting in there, freezing in the winter and bursting the pipe.

What's the problem? Well, as I'm filling in the trench and tossing some of the larger rocks into the woods, one of the rocks slips a little (they're muddy from the recent rains) and wouldn't you know it, is a direct hit on the vertical section of conduit at the pole. I guess it's a good thing the conduit was there, or it would likely have severed the fiber. But now there is a lovely crack in the conduit, through which water could infiltrate. The crack is extensive, probably extending 270 degrees around the pipe - but only about 3 inches in length along the pipe

It would be a huge hassle to remove the cable and fix this properly, and really I just want to repair it to the point of being impervious to the elements, and I'm wondering what the simplest way to do this would be. This is not an electrical line, and I'm pretty sure there is no building code that needs to be met for this repair. And the conduit was not even necessary in the first place! But the crack is a no-go.

I was thinking of these possible solutions: 1) some kind of sealant like flex-seal, or heck, maybe just some silicone caulk 2) bonding a pvc sleeve (pipe of a larger diameter) over the cracked portion using pvc solvent - though the sleeve would have to be cut lengthwise to get around the cable. Another possibility I just thought of is 3) using nylon string to cut the pipe below the crack and simply seal the entrance to the pipe there. This may be the best solution - the only drawback is that it protects the wire (which technically does not need protection) to a slightly lower height. I just have to remember not to throw any heavy, muddy rocks at it in the future ;-)

I guess I'm looking for the "best" solution that optimizes cost/ease of repair/durability.

Thanks in advance for any suggestions.
