Concrete Corrosion Control

How to control concrete corrosion is a question that our specialists are often asked. Our years of expertise in this field means that Churchills are the best people to answer this question for you.

The control of corrosion in reinforced concrete is an important aspect in conducting a successful long-lasting concrete repair. The greatest damage caused to concrete in structures is a result of corrosion exerted from within the embedded reinforcing bars to the surrounding concrete.

Corrosion is the natural process that occurs when the steel reinforcing bars within the reinforced structure are allowed to rust. As rust occupies a larger volume than the steel it surrounds it consequently exerts pressure on the encased concrete. This causes it to crack and damage the surrounding concrete surface.

Corrosion is allowed to propagate when aggressive materials that are harmful to steel reinforcing can penetrate the concrete surface and reach the steel reinforcement. This gives rise to what is known as either carbonation or chloride attack.

Corrosion control to reinforced concrete can be achieved using various techniques. One option is to apply anti-corrosion coatings to the surfaces of exposed concrete. The application of corrosion inhibitors can be applied to external concrete surfaces or applied directly onto the embedded steel reinforcing bars. Reinforcing bar corrosion barriers and protectors or the installation of embedded galvanic anodes are additional techniques.

All these control measures require specialist knowledge and expertise and here at Churchill Concrete Technology, we have the knowledge and expertise to undertake this type of work.

So, if you are searching for corrosion control options that will stop the spread of damage to concrete structures and protect against any further damage. Churchill Concrete Technology should be your service provider of choice.
