Από εγχειρίδιο μηχανήματος. Μείγμα χώματος με άλλα υλικά, το οποίο έχει μικρή ηλεκτρική αντίσταση και γι' αυτό χρησιμοποιείται για να πακτώνουμε τις ράβδους γείωσης βιομηχανικού εξοπλισμού, οι οποίες τοποθετούνται σε μια τρύπα που ανοίγουμε στο χώμα.

Earth rods are installed by one of two methods. More often than not, the rod can be driven into the ground by either a hand held hammer or mechanically operated hammer. However, where driving is difficult or progress non-existent, the only option is to drill a hole to take the earth rod. Where holes are drilled, the gap between the earth rod and wall of the drilled hole is commonly filled with a water expanding compound such as salt, coke/charcoal, and some red soil, this compound is called as “earthrite”.
