The rebar in concrete adds strength and stability to its build. These metal products sit inside concrete to reinforce it. Even though rebar is hidden inside its structure or surface, it can get damaged. If this happens, then the concrete itself might start to fail. How can you tell if your rebar has a problem?
1. You See Stains or Discoloration on a Concrete Surface.
Rebar damage can spread out and onto the surface of a piece of concrete. For example, if rebar rusts, then it can change shape. These changes can cause internal damage that allows the rust to spread out and onto the surface of the concrete. If this happens, then you will see rust-colored spots, stains, or areas of discoloration on parts of the surface closest to the rusting metal.
2. Your Concrete Shows Signs of Damage
If rebar corrodes, then it expands. Damaged rebar can also move out of position. These changes can affect the composition and structural integrity of the concrete. For example, if rebar expands, then it pushes against its surrounding concrete. This puts extra stress on the surface. It will be forced to move. So, you might notice surface cracks. If they are deep enough, the cracks might have a red/brown color in them if the rebar has corroded. Rebar problems can also make concrete surfaces spall or scale. Here, the concrete starts to chip away or flake.
If you have a significant rebar problem, then the concrete might start to bulge out in certain areas. If you don't fix the problem, then large parts of the surface might break away. This compounds the problem by exposing the underlying rebar which will become even more damaged if it is open to the elements.
3. Your Concrete Has Lost Structural Integrity
Concrete loses its original structural integrity for various reasons. For example, if you didn't use the right mix or strength of concrete, then it might not be fit for purpose. Eventually, it will fail. This can also happen if you have a rebar problem. Corroded, damaged, or inadequate rebar supports can affect the strength of a concrete surface or structure.
If parts of a concrete build are sagging or losing their ability to support other parts of your build, then your rebar might be at fault. If it isn't giving the right levels of internal support, then your concrete loses its strength. If you think you have rebar concrete damage, then contact concrete services contractors. They can assess your problem and recommend the best way to fix it.
