Concrete is apparently conductive enough.
A really good ground can be had by tying into the rebar (steel reinforcement bars)
embedded in a basement wall or the footing of a building or a concrete slab for a patio.
Something to keep in mind if ever doing new construction.
Maybe even worth digging a bit into the concrete of an existing structure,
assuming you don't compromise it structurally or create a groundwater leak.?
