Corrosion Control Engineering
Advanced cathodic protection design and corrosion analysis for buried metallic structures and pipelines.
Service Overview
E&S Grounding Solutions delivers cutting-edge corrosion analysis and cathodic protection design services that go far beyond traditional empirical methods. Our advanced computational capabilities address complex real-world scientific and engineering corrosion challenges with unmatched accuracy and realism.
Corrosion-related life-safety exposure represents a $48–70 billion annual expense in North America. According to a 2016 analysis by Johns Manville and NACE, corrosion costs the United States approximately $1.1 trillion annually — a 298.6% increase in nominal terms, escalating 3.5 times faster than inflation. Implementing proper cathodic protection requires an investment of less than 1% of overall costs and can yield a return on investment as high as 1:35.
E&S utilizes state-of-the-art tools including CorrCAD for precise analysis, complex multi-layer soil structure modeling, and polarization curve integration to deliver customized solutions that optimize performance and minimize costs.

Frequently Asked Questions
What is cathodic protection?
Cathodic protection is an electrochemical technique used to prevent corrosion of buried metallic structures such as pipelines, storage tanks, and foundations. It works by making the metal structure the cathode of an electrochemical cell, either through galvanic (sacrificial anode) or impressed current methods.
How much does cathodic protection save compared to corrosion repair?
Implementing proper cathodic protection requires an investment of less than 1% of overall infrastructure costs and can yield a return on investment as high as 1:35 compared to the cost of corrosion-related repairs and replacements. Corrosion costs the United States approximately $1.1 trillion annually.
What is the difference between ICCP and GACP cathodic protection?
Impressed Current Cathodic Protection (ICCP) uses an external power source to drive protective current through the structure. Galvanic Anode Cathodic Protection (GACP/SACP) uses sacrificial anodes made of zinc, magnesium, or aluminum that corrode preferentially to protect the structure. ICCP is used for large structures; GACP is used for smaller or isolated structures.
What is stray current corrosion?
Stray current corrosion occurs when electrical current from an external source (such as HVDC transmission lines or DC rail traction systems) flows through a buried metallic structure. Where the current leaves the structure, accelerated corrosion occurs. E&S Grounding Solutions specializes in stray current analysis and mitigation using CorrCAD software.
