Dealing with concrete spalling? Discover common causes and the best solutions to restore and protect your concrete surfaces.
Concrete is known for its strength and durability, but even the toughest surfaces can deteriorate over time. One of the most common and frustrating forms of concrete damage is concrete spalling — a condition where the surface flakes, chips, or peels away, exposing rough patches and sometimes even the steel reinforcement beneath. Whether you’re a homeowner, property manager, or contractor, understanding why spalling happens and how to fix it can save you time, money, and stress in the long run.
Concrete spalling doesn’t occur overnight. It’s typically the result of ongoing environmental exposure, installation issues, or internal stress within the concrete itself. Moisture is often the biggest culprit. When water penetrates concrete and temperatures fluctuate, freeze-thaw cycles can cause the trapped moisture to expand, creating internal pressure that leads to cracking and surface breakage. In coastal or humid environments, excess moisture combined with salt exposure can accelerate this process even further.
