    Default Ground rod thru slab? Thoughts?

    Can someone explain what is going on here, what the builder's thinking is? This can't be right.

    Although I normally see them inside and I have not seen one like that, it might be a Ufer ground.

    Looks like a driven ground rod that was not driven in all the way, that it was left out like that to show what happens when they are left out like that and left exposed to physical damage ... they were just being kind and showing why (one reason why) those ground rods should be driven all the way into the ground ...

    It was probably bent over after having be hit with the lawn mower so many times over the years.

    Jerry- Am I missing something? I do not see a bent over Ground Rod. Left out to show what happens ?? All I see is a ground rod up against the foundation

    Jack, that is angled towards the foundation, being as it is a bit difficult to drive a ground rod in at that angle with a house there I am guessing that it was bent over that way.

    Not Angled ( it's embedded ) top inch or so in the poured slab.

    To me it doesn't look embedded, it looks like someone applied parging or something to the side of the foundation/slab and when around, and part way over, the top of the ground rod.

    The ground rod would not have been driven before the foundation/slab was formed and poured, which means the ground rod was driven next to the foundation/slab and then bent over - probably at the time of construction and before the parging was applied.

    Do you also see it was "hit with the lawn mower so many times over the years."

    My guess is that the rod was installed horizontally into the slab before the slab was placed, and the end was bent down vertically 90 degrees to allow the form to be installed. After the form was stripped, the bar was pried away from the edge of the slab to allow for installation of the clamp, and the edge of the slab was then parged to cover the indention left by the bar. It should be easy to confirm by seeing how deep the bar goes down into the soil.

    Why ... why would the rod be installed horizontally into the slab at any time, before the slab was poured or not?

    What was the OP? Oh ya, thru da slab. Usually, it is during back fill where the conscientious excavator gently moves the grounding rod out of harms way.
    Not his fault, way up there on top of his rig. It is not so much that the rod itself can be damaged (bending is of no concern) but that 8ft+ is in the earth/foundation and more importantly that the GEC & connection is protected.
