Chemical Earth Rod (CHRD)
Chemical Earth Rod solves problems with conventional ground rods by requiring less ground and fewer electrodes to meet specified resistance. Each Chem-Rod creates an optimal electrical connection to the earth with a large conductive surface. The earth/electrode interface is further enhanced by conductive backfill and electrolytic salts, ensuring a consistent bed. The Chemical Rods filled with electrolytic salt come with an exothermically welded tail of either solid tinned or stranded bare copper wire. A test well is provided as well as a bentonite admixture for backfill, Some specifications call for the backfill material to be a non-corrosive form of bentonite clay free of polymer sealants that should absorb water.
