for Long-Term
Performance
The main cause of reinforced concrete deterioration is corrosion of the steel reinforcement. This is usually triggered by carbonation of the concrete at the steel depth or high levels of chloride ions at the concrete-steel interface. Over time, these processes allow water and oxygen to penetrate, accelerating corrosion and leading to concrete spalling.
By slowing the progression of carbonation and chloride ingress, we can significantly delay corrosion and extend the lifespan of a structure. Preventative measures focus on reducing the movement of these damaging agents into the concrete, protecting both its strength and appearance while avoiding costly repairs in the future.
Concrete
Protection Services
Our process begins with a detailed concrete condition survey, identifying carbonation depth and chloride levels in relation to the steel cover. Based on the findings, we determine the most appropriate corrosion prevention strategy. The most effective method is often a concrete coating, commonly known as an anti-carbonation coating, which limits the penetration of carbon dioxide, water, and oxygen.
CRL has extensive experience in concrete cleaning, preparation, and the application of a wide range of coatings, including anti-carbonation, penetrating hydrophobic coatings, migrating corrosion inhibitors, decorative coatings, and cementitious systems. Each application follows strict manufacturer guidelines to ensure long-lasting protection.

High-Quality
Results
Successful coating requires precise surface preparation and optimal environmental conditions. Our teams are trained in advanced preparation techniques to remove existing coatings and prepare surfaces for maximum adhesion. We also manage site conditions carefully, using heaters or dehumidifiers when needed, and monitor air and surface temperatures, humidity, and dew point to meet manufacturer specifications.
By combining skilled workmanship, specialist materials, and rigorous quality control, CRL ensures that concrete surfaces are protected effectively, prolonging structural life and maintaining safety and durability.
