In any case earthing capping is hardly practicable. Inaccessible joints
would have to be soldered,

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!

We were talking about joints in metal capping (aka channelling) which
tends only to come in 2 metre lengths.
