Rebar corrosion commences when materials that are harmful to steel, such as CO2 and chloride from de-icing salt, infiltrate concrete and reach the steel reinforcement. This triggers an electrochemical reaction, causing rust formation. Since rust occupies a larger volume than steel, it exerts internal pressure which causes the surrounding concrete to crack and become damaged. These cracks make their way to the concrete's surface, causing more CO2 and chloride to penetrate the concrete and speed up the corrosion process.

ALL Testing Solutions can test rebar in walls and floors to see if corrosion has taken place and to what level. We can do this without drilling or breaking up concrete wall or slab. Once we perform our testing, our report will help guide you to the next step in replacing damaged rebar.
