Concrete spalling can be triggered by several causes:
The most prominent cause in south Florida is primarily attributable to the brutal environment of South Florida, particularly along the coast. The air has a high content of humidity, and also a high content of calcium chloride (salt). Most buildings are constructed of either pre-cast or poured-in-place concrete. In both cases, concrete is a porous substance. When the "skin" (paint surface) of the building is not waterproof, the concrete absorbs the moisture and the salt from the air and the ground. This causes the steel reinforcing bars ("rebar") to rust.

SPALLING: Why it is a problem
Concrete spalling can result in a variety of undesirable outcomes:
Spalled surfaces can lead to rapid degradation of reinforcing steel which would jeopardize the integrity of structures and necessitate costly repairs. Spalls are also unsightly and indicate a lack of maintenance on the part of owners.
Remediation of spalling is a tedious and expensive process:
