Cathodic Protection
Impressed-current or galvanic systems that stop or slow corrosion in chloride-contaminated concrete without removing all contaminated material.
Cathodic protection is an electrochemical corrosion-control system — impressed current or galvanic sacrificial anodes — that stops or slows ongoing corrosion of reinforcing steel in chloride-contaminated concrete without removing all contaminated concrete.
Applied on parking garages, bridges, and marine/seawall structures when chloride content exceeds corrosion thresholds or spalling keeps recurring. References include NACE/AMPP SP0290 and ACI 222R.
We work with corrosion specialists to evaluate chloride profiles, half-cell potentials, and anode layout, then install and commission systems that protect remaining steel.
For heavily contaminated coastal structures, cathodic protection can dramatically reduce recurring patch cycles and preserve structural capacity long-term.
Key benefits
Triggered by
Chloride content above corrosion threshold or recurring spalling.
