Thereof, what causes spalling brick?
The flaking surface is a classic example of “spalling,” a type of failure caused by moisture and the freeze/thaw cycle. Water from rainfall, melting snow or even wet soil saturated the brick at some point, probably often, and froze inside the brick when the temperature dropped.
Why do brick faces fall off?
When the water melts and runs away or evaporates, it leaves a slightly larger crack which fills with water when it rains…. and so on until the face of the brick is more crack than brick and simply falls off! This is called freeze thaw action and is responsible for a great deal of damage to external walls.
