Apply a zinc-rich primer or rust inhibitor to the steel. toh rebar crack
Rebar corrosion occurs when the steel reinforcing bars in concrete are exposed to oxygen, moisture, and chloride ions (from sources such as deicing salts, seawater, or contaminated soil). This combination of factors leads to a chemical reaction that breaks down the steel, causing it to expand and put pressure on the surrounding concrete. A "TOH rebar crack" is more than just
