In any case earthing capping is hardly practicable. Inaccessible joints
would have to be soldered, which, if memory serves me right, would need
the use of acid cored solder or a similar type of flux which needs
thorough washing off to avoid corrosion.

You should not bury joints, a continuous wire should be installed, if the
wire you have availabe is not long enough, go out and buy some which is long
enough!
