Corrosion Protection Solutions

STRUCTURAL TECHNOLOGIES offers a full line of cathodic protection systems and has a staff of qualified professionals to help you design and customize your system and oversee installation by our licensed contracting companies.

ElectroTechCP™ EZ-Anode Systems

ElectroTechCP™ MCP Systems

ElectroTechCP™ ICCP Systems

ElectroTechCP™ EZ-Anode Systems are customizable galvanic cathodic protection solutions consisting of zinc mesh and a patented conductive mortar. The system is highly flexible as it is custom built and installed in the field for the long-term protection of reinforced concrete. Along with the base system, versions for different applications include: ElectroTechCP™ EZColumn System for concrete columns suffering from corrosioninduced damage and ElectroTechCP™ EZ-Joint System for concrete surrounding expansion/construction joints.

ElectroTechCP™ Metalized Cathodic Protection (MCP) systems deliver uniform corrosion protection to embedded reinforcing steel in concrete. Like other galvanic systems, the MCP system does not require external power. This spray applied anode (often referred to as metallizing) can be coated for aesthetic purposes or can be reapplied for extended service life. The MCP System protects embedded steel in concrete members as well as exposed steel members of structural steel.

ElectroTechCP™ Impressed Current Cathodic Protection (ICCP) systems involve installing anodes and ribbons throughout a structure and passing a Direct Current (DC) through them to prevent corrosion. The system is driven and controlled by proprietary power and monitoring devices that deliver and monitor precise levels of protective current to embedded steel within concrete structures. Variable power supplies and sophisticated controllers allow for different levels of protection that can be continually adjusted within the structure. The controllers allow for remote monitoring and will alert operators of changing conditions.
