Structural Repair
Concrete Repair: Remove the Cause Before Rebuilding the Surface
Spalling and exposed reinforcement are symptoms. Carbonation, chlorides, water ingress, poor cover or cracking may be driving deterioration.

Spalling recurs in coastal, parking or de-icing exposure.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Spalling recurs in coastal, parking or de-icing exposure.
Sample chloride profile and assess corrosion activity, cover and moisture routes.
Chlorides can sustain reinforcement corrosion beyond an isolated patch.
Engineer a system-wide repair and protection plan, potentially including corrosion control measures.
Avoid contaminating fresh repair materials and verify preparation to sound concrete.
Track corrosion indicators and inspect repaired and adjacent areas over time.
Do not assume rust removal at one patch eliminates chloride contamination nearby.
