Greg Batista explains how to repair concrete spalls, why it’s important, and how to avoid a big problem.
Concrete repair is a fact of life for an old building. This is especially true for buildings in South Florida. The “salt air” is the main reason for this concrete failure.
To put it another way, the salt chlorides in the air make their way into the concrete. Consequently, the rebar inside the existing concrete structure rusts and expands resulting in cracks and ruptures in the concrete.
This breach is called a “spall”. These spalls are considered a failure point and can compromise the structure’s integrity leading to a collapse. For this reason, Cities and Counties in South Florida take these matters very seriously which is why they are enforced during the building reinspection process.
