JAM Plus


Jam Plus and Earthing of Towers

Towers used for power distribution, lighting and communication aerials are usually supported on foundations with each leg on an individual concrete base or all legs on a reinforced concrete slab. Earthing is traditionally completed with earth electrodes using conventional earth rods or tapes.

  • Jam Plus conductive concrete has a resistivity of 0.1 ohm meter.
  • Jam Plus can be placed as a blinding layer when excavating the foundations and connected by copper tape to the tower.
  • Bore holes are not required thereby reducing drilling and copper costs.
  • By incorporating a blinding layer with the foundation block the area available is considerable when compared to a single electrode, enabling the resistance required to be achieved.
