It looks similar to this type of footing used with monolithic slabs:


The rebar from the footing is your Grounding Electrode. The tied on upright rebar is not per code, but neither is your copper rod. One single rebar in the footing and turned up or a piece of conductor are the proper choices,Yes, he connected the rebar in the ground with another rebar to the footing rebars.
Similar but not 1', has the barrier, not on undisturbed soil or even compacted by the looks of it. PP quality, let alone a grounding electrode.It looks similar to this type of footing used with monolithic slabs:

So even without the barrier you're saying the slab in the OP does not have a footing?Similar but not 1', has the barrier, not on undisturbed soil or even compacted by the looks of it. PP quality, let alone a grounding electrode.
Pretty much my thoughts.So even without the barrier you're saying the slab in the OP does not have a footing?
I thought that the NEC specifically allowed this type of footing to be used to creat a CEE.Pretty much my thoughts.
Ignoring the vapor barrier, if it were designed and installed correctly this could meet the definition of a monolithic footing as per post #24. The NEC does not define a footing so it is acceptable to use other resources for the definition. If the design used in the OP were considered a monolithic footing by local officials then it would need to be used as the CEE.Grounding electrodes are a waste of time generally but if that does not meet the requirements of a footing, how can it be considered for use as an encased electrode?
As has been discussed, with a vapor barrier there's no CEE, so something else would be required. Why not two rods though.I'm not understanding why a ground rod was installed in the first place?
I understand that, but from reading the OP, it doesn't sound like that was his intention by installing the rod. He never mentioned the vapor barrier, that was brought up by another poster.As has been discussed, with a vapor barrier there's no CEE, so something else would be required. Why not two rods though.
We would typically see those on water pipes but some of that style are also listed for rods.Appears the ground clamp he used is the type normally only used on copper tubing. The much heavier acorn ground rod fitting with a hex headed bolt is the only one we used on ground rods.
