Concrete spalling is very common in parking garages. The spalling occurs when the rebar in the concrete starts to corrode due to water seeping into the concrete. As the rebar corrodes it expands causing a piece of the concrete to break off.
Overhead spalling concrete can be dangerous to occupants in the parking garage. Pieces of concrete could fall and hit someone causing a lawsuit. It is relatively easy to repair the spalling concrete in the parking garage if done sooner than later. When rebar corrodes it could spread causing bigger areas to spall off.
