What Does the Repair of Corroded Concrete Involve? A Guide
Concrete is the backbone of countless industrial facilities, providing strength, containment, and safety for critical operations. But even the toughest concrete can be compromised over time—especially when exposed to water, chemicals, or harsh industrial conditions. Corrosion in concrete isn’t just a surface issue: left unchecked, it can threaten the integrity of tanks, containment areas, and structural supports, leading to costly downtime and safety risks.
Why Concrete Corrosion Demands Urgent Attention
Corroded concrete doesn’t just look unsightly; it’s an early warning sign of deeper problems. As cracks and corrosion develop, they allow moisture and aggressive chemicals to reach embedded rebar, accelerating the damage and undermining structural strength. Fast, effective repair is essential to keep your facility safe, compliant, and operational.
Step-by-Step Guide to Corroded Concrete Repair
1. Assessment and Diagnosis
Every successful repair starts with a thorough inspection. Trained professionals use visual checks, ultrasonic testing, and sometimes non-destructive acoustic methods to assess the extent of corrosion and identify the root cause—whether it’s chemical exposure, water ingress, or insufficient coatings.
2. Surface Preparation
The damaged area is carefully cleaned and prepped. This involves:
- Removing all loose, spalled, or delaminated concrete
- Abrasive blasting or power washing to eliminate rust, contaminants, and weak material
- Exposing and evaluating the condition of embedded rebar
3. Rebar Treatment and Reinforcement
Corroded steel reinforcement bars (rebar) are cleaned to bright metal, treated with corrosion-inhibiting primers, or replaced if necessary. In high-risk or high-stress environments, advanced solutions like carbon fiber wrapping may be used to reinforce and restore structural capacity—without major demolition or extended downtime.
4. Concrete Restoration
Specialty repair mortars, often polymer-modified or chemical-resistant, are applied to rebuild and restore the original shape of the structure. For containment areas or tanks, rapid-cure or trowel-applied linings are used to ensure chemical resistance and durability.
5. Protective Coatings and Linings
To prevent future corrosion, the repaired area—and often the entire structure—is coated with high-performance, industrial-grade linings. RAK Industrial Services specializes in plural component coatings, NSF 61-certified linings for potable water applications, and other customized solutions for aggressive environments.
6. Quality Control and Ongoing Monitoring
After repairs, thorough inspections and cure-time checks are performed. Ongoing monitoring—using modern inspection technologies—helps catch early signs of future corrosion, so you can address issues before they escalate.
