Earth rod into limestone

[farmerspark]

Evening all.

Been to start first fix of a couple of existing farm buildings. The owner has had a brand new 3 phase supply with no earth provided.

The issue is the farm buildings have been partially dug into a limestone hillside, no soil of any depth within 10m of buildings.

I'm looking for ideas for earthing, hammering rods in is impossible

Thanks

have you considered condu-disc / marconite - it doesnt need to be as deep as a normal rod.

drill the limestone first.

I di£ a thread on this ages ago. Lots of good ideas and they worked really well. I’ll try to find it.
