Steel Corrosion

Cold climates tend to exacerbate the failing condition of steel in concrete reinforcements. This is one of the most difficult situations to find and repair because, without a change in weather conditions, the steel will continue to eventually wear away. Without proper protection from the elements, the concrete structure will become brittle and unsafe.


When water that contains a high concentration of dissolved sulfates comes into contact with concrete, it will seep into the structure of the concrete, crystallize, and expand. This disrupts the structure and integrity in the strength of the concrete. Sulfates will also react with the cement paste, causing it to dissolve and erode. The third way that sulfates cause concrete to erode is attributed to high curing temperatures in precast concrete.


During the finishing process, if air or water gets trapped just below the surface of the concrete, the strength of the concrete will decrease. This will lead to a weakened horizontal plane across that particular area of the concrete. It usually happens when a professional applies a finish to the slab before the bleed water can reach the surface.


Every time concrete becomes saturated with moisture during freezing weather it endures pressure – this causes micro-cracking. Known as hydraulic pressure, over time the concrete will start to crumble and expose the aggregate. In cases when this issue isn’t immediately resolved, the entire concrete structure will eventually completely erode and disintegrate.  


In some cases, a reaction of alkali-silica will cause the concrete to crack. It happens when silica-containing aggregates react and form an expansive gel, which usually creates a map-like pattern across the surface of the concrete. You’ll notice this reaction by the gray or white gel on the surface or inside the voids.
