[QUOTE="Phoenix, post: 457796, member: 8133"] Not sure adding rods would give anything over what is there already... the columns set into the ground probably acheive a better Ra than a rod could. Need to decide if the risk is real or only exists in my mind. As to whole section this is a circuit with only about 5 columns on it most of which are around the pool area, it is separate from any other columns on site. As to other solutions, a bonded metal grid in the floor is sometimes advised... but cannot be retro fitted! Still, its one to worry about after christmas, wrapping is pending! [/QUOTE]
