By understanding the causes and effects of this problem, you can take steps to protect your property and prevent costly repairs in the future!


What Is Concrete Spalling?

The act of breaking into smaller pieces is referred to as spalling. Therefore, spalling is the process of cracking concrete into little pieces so that the air can access its interior. Concrete spalling is caused by certain chemical processes occurring within the concrete, which result in the creation of numerous unidentified chemicals. These modifications increase internal weight because there isn’t enough room in the concrete. Splits consequently take place to deliver the new weight outside.


What Are The Main Causes Of Concrete Spalling?

Concrete spalling slabs typically form as a result of excessive moisture and carbonation. However, there are several different ways that concrete can spall. They consist of:


  • Poor construction practices: Concrete spalling can be caused by poor construction and design of the concrete itself, such as using substandard materials or not properly reinforcing the structure.


  • Exposure to harsh weather conditions: Concrete is particularly prone to damage from extreme temperatures, excessive moisture, freezing and thawing cycles, as well as UV rays from direct sunlight. All of these factors can weaken the integrity of your concrete surface over time, leading to spalling and cracks.


  • Defects in material quality: Even if a concrete slab is constructed correctly with high-quality materials, it still may experience spalling due to small flaws in the makeup of its components. These flaws could include anything from impurities in cement mixers to improper curing practices.


What Are The Signs Of Concrete Spalling?

A concrete surface degrading over time is referred to as spalling. As the problem worsens, bits of concrete start to fall out in addition to the initial fracture line that forms. Moisture getting into the layer protecting the steel reinforcements in the column, beam, or foundation pier causes concrete to spall. The steel inside the beam begins to rust over time. Cracks also appear at the surface above the supporting steel because of the expansion process’s sluggish but forceful movement. Since the exposed break allows more moisture to hasten the corrosion, the harm is gradual. Commonly referred to as the iron oxide scale, it causes the crack to widen even further.

What Can You Do To Fix Or Prevent Concrete Spalling?

There are a number of steps that you can take to prevent or fix concrete spalling, including:

  • Ensuring that your property is properly waterproofed and protected from moisture exposure. This includes ensuring that your gutters and downspouts are working properly and draining away from your building. It may also involve installing waterproofing membranes over vulnerable areas like basements or foundations.
  • Regularly inspect the condition of your concrete surface, looking for cracks or signs of spalling. If you notice any issues with your concrete, it is important to address them as soon as possible to prevent further damage from occurring.
  • Sealing holes and cracks well before they become an issue can help prevent moisture from getting in and causing spalling.
  • Adding a protective coating to your concrete surfaces, such as a layer of epoxy or polyurethane, can also help protect against moisture damage and other forms of deterioration.
  • If you are dealing with severe concrete spalling issues on your property, you may need to consider fully replacing the damaged concrete altogether. This can be a costly but necessary step in ensuring that your building is properly protected against further damage.
  • Seeking out professional help if you need assistance with repairing or reinforcing damaged concrete surfaces on your property. Concrete spalling can be a serious problem, so it is important to take the necessary steps to address any issues as soon as possible. With the right knowledge and tools, you can keep your property safe from concrete spalling!​ ​​ ​​ ​​​​ ​​ ​​​​​​​​​​​​
