I was attacking the ivy on the side of my garage with a spade and
accidentally bashed a cable that goes from the house to the garage.

The outer sheath has a nick where it bends into the wall. Do I need to
worry about it? It is proper underground cable installed by the house
builder in 1988. Armoured with earthed wires.

Do I need to patch the sheath?



The armouring is at risk of rusting now. But it's fully fixable:

Self amalgamating electrical tape. Dry everything, wrap several layers
*tightly* (this is key - the tape should stretch as you go - leave no
air gaps).

Work from one end, an inch past the nick, then over an inch past the
other way, then back and forth.

Me: I'd make 3 passes. It'll weld into a solid mass, is fully weather proof.

The used to use this to complete underground cable joints decades ago.
