A repair is always possible, but depending on how damaged it is in the segment it might need two joints and a new small section inserted.

But I would start by cutting mid-damage and seeing if it looks clean enough that it can simply be joined in a suitable torpedo style of resin joint. Something like this:

As the cable has not been installed yet you can easily do an IR test (having checked the far end is clear of any shorts, etc) to get an idea if it is OK even before you start cutting (which you should not do until you are ready with a joint to finish it).

Edit: I would try and simply part the cores, etc, without cutting through, it is best if you don't have actual joints and simply use the resin unit to allow it to be inspected and covered over if no real damage is seen.
 
I hope that’s not a concentric, with the red core showing.
Could be a DNO job.

Slightly more mangled than I thought at first… a little bit of tape isn’t going to help.

Did you not see the yellow warning tape?
see y last thread, the inner insulation is red. see the pics. Ill give it a thorough inspection first
 
As @pc1966 said it's likely you won't have to completely cut it and start again, probably just get a torpedo case around it if IR readings are ok.

They are actually quite easy to use. This video shows the whole process.


Absolute worst case is two joints and a new section, like this one I had to do:

Thanks pc1966 - ill clean the muck off remove the damaged outer sheathing and then inspect and use the resin cover without cutting the cables if there is no visible damage. ill post pics once completed
 
If you’re absolutely sure there’s no damage to the inner cores, or the breaks in the armour strands, then wrap self-amalgamating tape around it.
It’s more waterproof than insulating tape.

For something that looks more professional… get an underground torpedo joint….
Don’t make a joint, but encase the damaged section within the torpedo and fill with resin as normal.

Have you got a photo? Some repairs are more suitable depending on severity of damage.

When he said nicked the outer sheath. i was thinking a small cut and was going to say just wrap a load of electrical tape or heat shrink to protect the SWA from getting rusty.. I guess this highlights the problem with forums, one persons nicked it with a spade is another persons mashed it with a spade..

I got it from one of my usual local merchants.
Screwfix sell them, search "resin joint"

I wouldn't recommend insulating tape. Self-amalgamating tape is more appropriate.
