No animals anymore. Just a big old historic barn that the local yokels are trying to preserve. The service is the most structurally sound part of the building!

My water-well casing reads a solid two ohms by the three-point method, but the place was built in 1935. Drillers haven't used steel for domestic-well casing for ~30 years in this area.
Regardless of test numbers, nothing can prevent destruction from a direct lightning hit.

Thank you for the info guys. A commercial property is completely covered by a 6 inch thick concrete slab. They saw cut the concrete for plumbing equipment. I will drive the ground rods in the trench area and the acorns will be buried below the concrete. I was worried I'd have to block out the concrete for access to the acorns.

zapped — for 8-inch or less casings [maybe larger] — it's PVC.

As far as test instruments, local AEMC and Megger reps may be able to demonstrate their wares on your jobsite. Short-term rental may be another option.

Bury the rods in the concrete! My inspector claims the concrete has the right moisture content and that it stays steady.
