How Salt Air Impacts Concrete, Steel, and Roofing Systems

What Is Salt Air Exposure?

Salt air refers to airborne salt particles (sodium chloride) carried inland from the ocean. These particles settle on building surfaces and combine with moisture from humidity, rain, and condensation.

This creates a highly corrosive environment that accelerates the breakdown of common construction materials, especially in coastal regions like Florida.

The Impact on Concrete

While concrete is a durable, long-lasting material, in coastal environments, it is still vulnerable to salt intrusion.

Chloride Intrusion and Spalling

Salt particles penetrate the concrete surface over time and reach the embedded reinforcing steel, also known as rebar. This leads to corrosion of the steel, which expands and causes the surrounding concrete to crack and break apart. This process is known as spalling.

Cracking and Delamination

As corrosion progresses, internal pressure builds within the concrete, leading to cracking and subsurface separation, also known as delamination. These issues often go unnoticed until visible damage appears on the surface.

Why Coastal Buildings Require Proactive Maintenance

Because salt air accelerates deterioration, coastal properties require a more proactive approach to maintenance and inspection.

Key strategies include:

• Regular structural and roofing inspections
• Early repair of cracks, spalling, and coating failures
• Application of protective coatings and waterproofing systems
• Monitoring drainage and moisture intrusion
• Ensuring proper installation of corrosion-resistant materials

PROJECT SPOTLIGHT

Project: Cape Shores

Location: Cape Canaveral, Florida

Scope of Work: Concrete Restoration

Keystone Engineering is proud to announce the successful completion of a large-scale concrete restoration project at Cape Shores in Cape Canaveral. Spanning two years and valued at approximately $3 million, this project included 20 two-story buildings, each consisting of 10 residential units.

From initial inspections through final construction, Keystone provided comprehensive engineering oversight to ensure quality, accuracy, and long-term performance.

Project Planning & Preparation

The project began with detailed structural inspections of all 20 buildings. These evaluations allowed Keystone to identify areas of deterioration and develop individualized repair budgets for each structure.

To support a competitive and transparent process:

• The project was put out for competitive bidding
• Detailed permitting documents were prepared for submission to the City of Cape Canaveral
• A comprehensive project manual and specifications were established

This early-stage planning ensured the project started with a clear roadmap for success.

Concrete Restoration Process

During construction, Keystone’s field inspectors played a critical role in identifying and marking areas of damaged concrete requiring repair.

Key steps included:

• Marking areas of deterioration on balcony and walkway slabs
• Performing pre-pour inspections to verify repairs met industry standards
• Tracking and documenting repair quantities for accurate billing

One of the biggest challenges was accessing repair areas, as many units had screen enclosures, glass enclosures, and a variety of existing floor finishes such as tile, carpet, and deteriorated coatings. Careful coordination was required to complete repairs while minimizing disruption to residents.


A Successful Outcome

After two years of planning, coordination, and construction, the Cape Shores project is now complete. The result is a safer, more durable, and visually enhanced community built to withstand Florida’s coastal environment.

Projects of this scale highlight the importance of engineering oversight, detailed planning, and quality execution in extending the life of residential buildings.
