Cathodic Protection Theory &<br />
Application<br />
1) Cathodic Protection is an electrical method of preventing corrosion on<br />
metallic structures which are in electrolytes such as soil.<br />
2) There are two basic mechanisms by which metals corrode Electrolytic<br />
Corrosion <strong>and</strong> Galvanic Corrosion<br />
3) Galvanic Corrosion occurs due to differences in the electrolyte (soil) itself<br />
<strong>and</strong> is considered the “Natural” Process of corrosion.<br />
4) In the process of Galvanic Corrosion the steel member is considered the<br />
Anode.<br />
5) By installation of a Sacrificial Anode Cathodic Protection System e a higher<br />
negative potential causes current to flow onto the anode <strong>and</strong> negates the<br />
process of Galvanic Corrosion.<br />
6) Zinc <strong>and</strong> Magnesium are the two most common sacrificial anodes.<br />
7) The Sacrificial Anode corrodes over time <strong>and</strong> must be checked <strong>and</strong><br />
replaced at given intervals<br />
8) Soil Composition, Soil PH, <strong>and</strong> Soil Moisture Levels all play a role in Anode<br />
selection <strong>and</strong> life expectancy.

Comprehensive <strong>Guy</strong> <strong>Anchor</strong> Protection<br />
Plan<br />
1) Inspection/Restoration of Existing<br />
2) Evaluation during inspections for current or future potential problems.<br />
3) Without further analysis from a Structural Engineer, remediation is<br />
deemed necessary if anchor has degraded 5% from its original size.<br />
4) Determination after initial inspections what the duration between<br />
inspections should be based on site specific conditions.<br />
5) <strong>Remediation</strong> of site if site is deemed to have failures<br />
6) Protection of both existing anchors left in service, <strong>and</strong> new anchors<br />
installed as part of the remediation process.<br />
7) Cathodic Protection installation, or Concrete Encasement.<br />
8) Monitoring of any Caothodic Protection Systems that are deployed.
