Concrete seems stable and permanent, but it remains porous and will absorb water. When this water trapped inside the concrete freezes, it pushes the cement binder apart. This expansion, and the resulting contraction when the water melts again, cause crumbling.
Why Is My Concrete Crumbling?
Concrete is a very strong material, and when it is properly installed and maintained, it can last for many years without needing any repairs. Unfortunately, even the best-installed concrete can eventually crumble and break apart. There are several potential causes of concrete crumbling, and understanding why your concrete is grinding can help you take the necessary steps to repair the issue and ensure it doesn’t happen again.
One of the most common causes of concrete crumbling is poor installation. If the surface wasn’t adequately leveled or the concrete wasn’t mixed correctly, it could cause the material to be weaker than it should be. Over time, this weakened concrete can start to break apart and crumble. Similarly, if the concrete was installed during the wrong time of year or if a nasty mix of concrete was used, these issues can lead to sudden crumbling.
Another common cause of concrete crumbling is exposure to extreme weather. If your concrete is regularly exposed to freezing temperatures, the water in the concrete can expand and contract with the changing temperatures. This can cause cracking and crumbling over time as the concrete cannot withstand the stress of the changing temperature. Similarly, if your concrete is regularly exposed to intense heat, the surface can become
