[TheForge] Grounding Points in Concrete Floors

[Woolley]

Greetings,

I've seen some of the posts on new concrete floors being poured with grounding points for welding etc.at various places.  I'm about to do the same thing and was wondering what everyone used (must have missed this) as their ground path underground.  I was going to use 1/2 rebar (I know rebar is a # size, can't remember it) for my path, and basically bring it above the concrete at various spots along the perimeter walls.  Is this sufficient?  Will the heat conducted thru the path adversely effect the concrete? Thanks.

Regards,
