Migrating Corrosion Inhibitor (MCI)
Topical migrating corrosion inhibitor that diffuses through concrete to passivate embedded reinforcement.
Overview
Stops corrosion. From the outside in.
Migrating Corrosion Inhibitor is a surface-applied liquid that penetrates hardened concrete and migrates by vapour and liquid diffusion to reach embedded reinforcement, forming a protective film on the steel surface.
The non-invasive alternative to full concrete repair on structures with widespread but early-stage corrosion.
Key Features
- Surface-applied – no concrete removal
- Migrates through concrete
- Penetrates up to 100 mm of cover
- Forms protective film on rebar
- Suppresses anodic and cathodic corrosion
- Extends service life 5–15 years per treatment
