Question Caravan site earthing
Anyone know how I can get a good earth for caravan site
installation. Earth stakes, even extended, appear to dry out after a
short time and readings go sky high.

the NEC settles the problem by allowing for the use of a second (just as ineffective) rod.
might work for you too.

When i worked on the electrickery board we used to dig gimantic hole,lob an earth matt in and bung a load of bentonite over and around it or if it was really poor subsoil we used to bore out a post hole and put rods in and backfill with bentonite always held the moisture.

Follow the code but you must always remember that the NEC is the MINIMUM. I would do extra and measure ,again.

take every alternate caravan. dig a large hole and push caravan into hole. bond all together with some 70mm. crush each van with the 'back actor' on a JCB. Backfill. Job done

On a more serious note; would burying an earth plate be any better than a rod?...just thinking it would need a larger area to dry out. or a plate AND a rod maybe

after you salt the rod, have a plumber install a leaky hose bib near it.
