Norcure Re-alkalization is a treatment that restores the alkalinity of carbonated concrete and reinstates the passivity of steel reinforcement. Re-alkalization is carried out by temporarily applying an electric field between the reinforcement in the concrete and an externally mounted anode mesh. When the process is complete, the pH of the concrete is greater than 10 which is sufficient to provide lasting protection to the reinforcing steel.
| Applications:
- Facades
- Columns
- Beams
- Other carbonated areas

Features and Benefits
- Mitigates active corrosion – addresses the cause of corrosion by re-establishing a high pH environment and repassivating the reinforcing steel.
- Long term protection – structure will not re-carbonate in the treated areas.
- Global protection – treats the entire structure, not just isolated patches.
- Low maintenance – no permanent system to maintain or monitor.
- Environmentally friendly – vastly reduced concrete break-out reduces noise, dust and environmental pollution.
