Cathodic Protection

Helping clients & owners improve asset utilization by providing steel infrastructure protection via installation of cathodic protection systems is what EXARO does.
  • Install galvanic and impressed current systems (shallow and deep well) on any type of steel structure including water reservoirs, buildings, water and gas pipelines, bridges, parking structures.
  • EXARO also provides turnkey design/installation services by partnering with our corrosion engineering firm.
  • Cathodic protection is an engineered method of controlling and slowing down metal corrosion thereby extending the useful service life of an asset.
  • The method requires another metal to be sacrificed in place of the metal under protection; this sacrificial metal is referred to as the anode.

There are two types of cathodic protection systems:

  • Passive and sacrificial
  • Dynamic requires an external DC current to operate
