The Use of Concrete-Enclosed Reinforcing Rods as Grounding Electrodes

 

The findings of Ufer that metal encased in concrete performs as an effective grounding electrode constitutes a major breakthrough in grounding technology. This has been recognized to the extent that copper wire embedded in the concrete footings of a structure is now an acceptable alternate to driven rods or pipe electrodes in the soil. This comes as a welcome relief from the condition of ineffective grounding by the use of water pipes due to insulated material or couplings and the antagonism of the proprietors of the water pipes.
