Summary
Concrete repair isn’t just a maintenance task in Florida—it’s part of a billion-dollar industry that keeps engineers, contractors, and lawyers very busy. From salt and humidity eating away at steel to aging buildings now facing stricter post-Surfside laws, Florida sits at the center of concrete repairs. In this article, I’ll explain why our coastal environment makes us ground zero for spalling, what the new rules mean, and why fixing concrete is never just a matter of sprinkling some magic dust.
Why Florida is at the Center of this Billion-Dollar Industry
When people outside the Sunshine State think of Florida, they picture retirees, iguanas sunning themselves on rooftops, and hurricanes that make the Weather Channel anchors stand sideways in the wind. What they usually don’t think of is concrete repair. Yet here, concrete repair is as much a part of life as sunscreen and toll roads.
So why is this so prevalent in Florida? The answer comes down to three major villains and one very important new referee:
- Salt and ocean air (chloride ions that love eating steel for breakfast).
- Humidity and rain (moisture is like the gasoline on the fire).
- Aging building stock (some of it more than 100 years old in places like South Beach).
- Post-Surfside laws and regulations (the referee blowing the whistle harder than ever before).
Put these together and you have the perfect recipe for concrete spalling, multimillion-dollar repairs, and, in many cases, lawsuits when boards, residents, contractors, or owners try to cut corners.

Salt, Humidity, and the Ocean: Florida’s Three Musketeers of Corrosion
Let’s start with our environment. Salt air is basically the “hiding stalker” of concrete deterioration—it sneaks in through microscopic pores, finds the reinforcing steel (rebar), and starts a corrosion party. When steel rusts, it expands, pushing out against the concrete cover. That’s when you see cracks, bulges, and chunks falling off your balcony.
Now, add Florida’s humidity into the mix. We don’t just get humid; we practically breathe soup for six months of the year. Moisture keeps the steel perpetually wet, which is exactly what corrosion needs to thrive. Pair that with common rainstorms and the occasional hurricane, and you’ve got conditions that would make even the best concrete tremble.
Finally, there’s the ocean. For seaside condos in Miami Beach, Hollywood, or Fort Lauderdale, salt spray acts like free delivery service for chloride ions. Even buildings that are set back from the beach still deal with wind-blown salt. The American Concrete Institute notes that coastal environments are some of the harshest for reinforced concrete, requiring special durability design (Source: American Concrete Institute, ACI 562-19).
It’s no wonder so many of my inspections feel like I’m walking into a CSI episode for concrete.
Aging Buildings: Florida’s Time Bombs
Miami-Dade and Broward counties are full of buildings that were thrown up during the condo boom of the 1960s and 1970s. Many of these are now 50+ years old, and some historic buildings in South Beach are over 100 years old and still in active use. According to the Miami-Dade County Property Appraiser’s data, nearly half of Miami Beach’s condo inventory was built before 1980 (Source: Miami-Dade County Property Appraiser).
That means tens of thousands of units are now at or past the age when significant structural repairs are unavoidable. If you own one of these buildings, congratulations—you basically own a classic car. It may look great from a distance, but under the hood the rust is spreading fast, and the mechanic (in this case, your engineer) is about to hand you a very large bill.
The truth is that aging reinforced concrete doesn’t just need cosmetic touch-ups. By the time spalling shows up on the surface, it usually means there’s a deeper structural issue brewing.
The New Laws After Surfside
On June 24, 2021, the Champlain Towers South collapsed in Surfside, killing 98 people. This tragedy shook the entire country and permanently changed the way Florida regulates building safety. The new laws passed in 2022 and updated in 2023 mandate stricter timelines and reserve funding requirements:
- Milestone inspections are now required statewide for condos and co-ops three stories or higher.
- Buildings must complete their first inspection at 30 years old, or 25 years old if located within three miles of the coast. After that, inspections repeat every 10 years.
- Structural Integrity Reserve Studies (SIRS) are required so boards can no longer waive reserves for major structural elements. That means setting aside millions for future concrete repairs whether you like it or not.
(Source: Florida Statutes 553.899 and 718.112; Florida Building Commission updates).
These new regulations are like the state saying, “No more kicking the can down the road.” For boards, that means bracing residents for mandatory assessments. For engineers like me, it means a steady stream of inspection calls. For concrete contractors, it means business is booming—sometimes literally.
Table: Why Florida Is at the Epicenter of Concrete Repair
Here’s a breakdown of the major culprits that make Florida ground zero for concrete repair:
| Culprit | How It Damages Concrete | Impact on Florida Buildings |
|---|---|---|
| Salt Air (Chlorides) | Penetrates pores, corrodes reinforcing steel | Accelerates spalling, especially near the coast |
| Humidity & Rain | Keeps concrete perpetually moist | Promotes rust, mold, and weakens structural integrity |
| Ocean Proximity | Constant exposure to salt spray and storms | Higher repair frequency for seaside condos |
| Aging Building Stock | Many condos 40+ years old (some 100+) | Major repairs required for recertification |
| New Post-Surfside Laws | Mandated inspections & reserve studies | Multi-million dollar repair obligations |
True Story to Learn From
Years ago, I was the engineer and contractor on a building in South Beach right on the ocean. Up to that point, it was the worst case of concrete deterioration I had ever seen. Balconies were crumbling, the garage looked like it had been used for target practice, and the rebar was so rusted I thought about bringing a tetanus shot just to walk the site.
I sat down with the Board and told them bluntly: “You’ve got two choices. Repair this building at great cost, or tear it down and start over.” Their jaws dropped. But here’s the kicker: tearing it down wasn’t really an option. The building was historic, and zoning laws had changed so much that a new structure wouldn’t have come close to matching the old one.
So, they bit the bullet and chose repairs. The project took nearly two years and cost almost as much as building a new tower. But when it was done, the building looked brand new, the units skyrocketed in value, and the owners had the peace of mind of knowing their building wasn’t about to join the Surfside cautionary tale.
The moral? Concrete repair isn’t optional in Florida. It’s survival.
Different Perspectives
I’ve actually heard people argue that concrete repairs are exaggerated by engineers and contractors looking for work. I’ve heard residents mutter under their breath during board meetings, “This is just a scam to line their pockets.” Others point to chemical products advertised as “miracle cures” that supposedly stop corrosion without the need for messy repairs.
Here’s the problem: the science doesn’t back those claims. The American Concrete Institute and the International Concrete Repair Institute are clear that once steel reinforcement is actively corroding, the only durable fix involves removing deteriorated concrete, cleaning the steel, and patching with repair mortar (Source: International Concrete Repair Institute Guidelines). Anything else is like putting a Band-Aid on a broken bone. I would also say that Cathodic protection is also a very viable alternative (more on that in another article).
As for the suspicion about engineers? Trust me, I don’t get any joy from telling a group of retirees their maintenance fees are about to triple. It makes me about as popular as a mosquito at a barbecue. But ignoring the problem doesn’t make it cheaper—it only makes it worse.
