As per NEC, concrete is required.

250.52 Grounding Electrodes.
(3) Concrete-Encased Electrode. An electrode encased by at least 50 mm (2 in.) of concrete, located horizontally near the bottom or vertically, and within that portion of a concrete foundation or footing that is in direct contact with the earth, consisting of at least 6.0 m (20 ft) of one or more bare or zinc galvanized or other electrically conductive coated steel reinforcing bars or rods of not less than 13 mm (? in.) in diameter, or consisting of at least 6.0 m (20 ft) of bare copper conductor not smaller than 4 AWG. Reinforcing bars shall be permitted to be bonded together by the usual steel tie wires or other effective means. Where multiple concrete-encased electrodes are present at a building or structure, it shall be permissible to bond only one into the grounding electrode system.

It's refered to as a concrete encased electrode.

No concrete no....well, you get the point.

Ufer is slang I believe. The name has a history, but I forget.

The concrete encased electrode - CEE - (ufer) is described as one of over seven electrodes we can use in 250.52.

Welcome Jesse7623!

An electrode is required if this is a separate structure unless its only supplied with a single branch circuit including a multiwire branch circuit.

If it is just an addition to an existing structure the electrode should be existing as well you are not required to add more electrodes. Rebar does not qualify as ?an electrode? just because its there it is only ?an electrode? if it is installed in accordance with all the criteria of 250.52(A)(3).
