The main component of the Tyfo® CP System is a zinc or titanium oxide mesh as the sacrificial anode. It prevents future corrosion in structural steel since their electrochemical potential and consumption rate are superior than steel. The intent of the sacrificial anode is for it to corrode instead of the steel reinforcement in the structure. As the cathode in the electrochemical cell, the steel reinforcement is protected from corrosion.
Tyfo® P-E Grout acts as the electrolyte to complete the circuit.
The Tyfo® SEH and SCH Systems can be used to anchor the cathodic protection system. The Tyfo® SEH and SCH can also serve as additional protection from the elements and as structural strengthening.
Tyfo® MC (monitoring cables) can be added to measure electric potentials and inversely the corrosion rates.
