Introduction
The Problem
Concrete buildings are susceptible to various forms of deterioration over time, particularly due to corrosion of reinforcing steel, exposure to moisture, and the penetration of chloride ions. These factors lead to cracking, spalling, and weakening of the structure, threatening its long-term durability and safety. Effective corrosion mitigation strategies are essential to extend the service life of reinforced concrete structures.
Mitigation Strategy
To preserve and protect buildings from corrosion and environmental damage, we recommend a three-part system:
Corrosion Inhibition: The first step in the process is to stop existing corrosion activity and prevent future corrosion potential by forming a passivating layer on the steel. To this end, apply a migrating, volatile, surface-applied corrosion inhibitor to halt existing corrosion and provide long-term protection to the steel reinforcement.
Concrete Strengthening: Use a silicate-based treatment to strengthen the concrete, reduce its porosity and permeability to prevent moisture ingress and further prevent corrosion.
Water Repellency: Apply a hydrophobic surface coating to prevent water and chloride ingress, reducing the potential for future damage.
Optional Reinforcement: For areas requiring additional load-bearing capacity, FRP reinforcement is available. This advanced solution, as detailed in our FRP ++ Case Study, provides extra structural support where necessary, ensuring enhanced stability and durability for high-stress applications.
