What causes concrete to crack and pop?
Spalling, also called scaling, occurs when excess water intrudes in the concrete’s structure, creating stresses that eventually cause flaking, peeling, or pitting. In extreme cases, even deeper chunks of concrete may pop off. The excess water may get in the concrete through cracks, or the concrete could have been improperly mixed when it was laid. Improper curing or poor hardening can also increase spalling, as can the use of deicing chemicals or salts on concrete. Spalling is particularly common and widespread in areas with extreme freezing and thawing cycles, when water expansion in the concrete will multiply the pressure and force to expel the spalls.
