Definition: Spalling is a result of water entering brick, concrete or natural stone and forcing the surface to peel, pop out or flake off. This is because there is salt in water. Salt pushes outward from the inside. Eventually, spalling can cause crumbling and destruction of a structure.
Also Known As: Flaking, especially in limestone
Common Misspellings: spaulding, spalding
Examples: Due to spalling, some bricks in the foundation had to be replaced because the original bricks had crumbled.
