Where I am located the ufer consists of the required amount of rebar encased and it is then turned up to extend through the basement floor, on the interior of the building, for us to attatch to at a later date. Does the connection to that rebar need to be encased in concrete or can it be exposed in the unfinished basement area? 250.52 A 3 1 makes no mention of this but 250.52 A 3 2 says metallic components. clamps I guess, must be encased when the #4 is the electrode.
