A spalling column is a column losing capacity. We treat the rebar, rebuild the section, and protect against future moisture intrusion — before an engineer flags it.
Column spall repair in Fort Lauderdale is a structural priority — not a cosmetic one. Load-bearing columns are among the most critical structural elements in any multi-story building, and spalling on a column face is a direct signal that rebar corrosion is actively undermining its capacity. At Planet Construction FL, we treat column spalling with the structural seriousness it deserves: full removal of all compromised concrete, rebar corrosion treatment, and mortar restoration using FDOT-approved systems that restore load-carrying capacity and defend against future deterioration.
Full 360° rebar undercut, mechanical rust descaling to bare metal, and cathodic zinc primer application.
Engineered multi-tier shoring towers safely support live and dead superstructure loads prior to chipping.
Turnkey threshold special inspections, concrete cylinder break tests, and final municipal certificate of completion.
A column with spalling and exposed rebar is a column losing structural capacity in real time. Florida's salt-laden air accelerates the corrosion cycle, and the concrete cover that once protected the steel is now gone. Engineers flag spalled columns immediately during inspections — and rightly so, because they're load-bearing elements actively losing strength.
We follow engineering guidance from the first cut: chip out damaged concrete, expose and clean all corroded rebar, treat the steel with inhibitors, replace rebar where needed, and rebuild the column section with high-strength repair materials. Every step is photographed and documented, so engineers and inspectors get the proof they need. The column comes back to full structural capacity.
Column spalling in Fort Lauderdale's buildings is almost always driven by rebar corrosion. Salt air penetrates the concrete cover, chloride ions reach the embedded steel reinforcement, and corrosion begins. As the steel corrodes, it expands — applying internal pressure that fractures and separates the concrete cover from the column face. In South Florida, this process is accelerated by the near-constant humidity and salt air exposure that coastal buildings experience year-round. Columns in parking garages, ground-level applications, covered walkways, and building perimeters adjacent to vegetation or irrigation are among the most frequently affected. The longer corrosion progresses before repair, the greater the section loss in the rebar and the more significant the required repair scope.

As corrosion reduces the rebar's effective cross-section, the column's ability to carry axial load and resist lateral forces decreases. The rate of capacity reduction depends on the degree of corrosion and the original reinforcement design, and cannot be determined by visual inspection alone. Severely corroded columns in buildings with minimal structural redundancy present a genuine risk in extreme load events. Planet Construction FL recommends that any column showing active spalling or rebar exposure receive a structural assessment — not just a repair quote — before restoration work begins.
Concrete structural restorations intersect with waterproofing membranes, expansion joints, and municipal milestone permits. Dividing trades creates delays, finger-pointing, and voided warranties.
Separate concrete patchers, painters, and coating contractors frequently void each other's warranties. If water intrusion recurs, the waterproofer blames the concrete mortar while the mason blames the sealant.
John Kraja directly manages the entire structural restoration under dual state licenses (CGC1517295 & CCC1329271). In-house crews chip spalls, treat rebar, cast structural mortars, and apply warranted traffic coatings under single-source accountability.
We pull permits directly across Fort Lauderdale, Pompano Beach, Hollywood, Boca Raton, and Weston building departments. We coordinate engineering special inspections daily to prevent costly stop-work delays.
Column spall repair follows a precise protocol. First, all delaminated concrete is removed to the full extent of the damage zone — we sound the entire column face to identify every compromised area, not just the visually obvious spalls. Next, all exposed rebar is wire-brushed clean and evaluated for section loss. Corrosion inhibitor primer is applied to all exposed rebar, and supplemental rebar is added where section loss exceeds acceptable thresholds per engineering specifications. FDOT-approved repair mortars are applied in properly bonded layers — building the column back to its original profile with material that bonds chemically and mechanically to the existing substrate. Final surface treatment — coating, paint, or stucco to match surrounding finishes — completes the restoration.
Technicians review engineer reports and conduct acoustical hammer sounding surveys to map hidden subsurface delaminations.

The most important and most frequently shortcut step in column spall repair is rebar treatment. Simply patching over corroded rebar without treatment means the corrosion continues beneath the new patch — and the repair fails faster than the original concrete did. Planet Construction FL treats every exposed rebar bar with corrosion inhibitor primer before any patch mortar is applied. Where rebar has been exposed at multiple points along a column, the full length of the rebar between exposed zones is assessed and treated — not just the visible end points of the damage. This approach, combined with the inherent corrosion resistance of FDOT-approved repair mortars, is what separates a lasting column repair from a patch that fails in two years.

Cosmetic spalling — a thin surface layer without rebar exposure — is generally a maintenance issue. The moment rebar is visible, or when spalling covers a significant portion of the column face, structural assessment is warranted. Diagonal cracking on a column face, spalling at the column base or cap, and any column showing rust staining combined with active concrete loss should be assessed by a licensed contractor and, in many cases, a structural engineer.
Yes. Column repairs in occupied parking garages and buildings are performed regularly with proper safety barrier placement. Vehicle and pedestrian traffic is redirected around the active work area. Chipping and grinding operations are scheduled to minimize impact on building operations. We coordinate with property managers on access and scheduling before work begins.
Spalling columns are among the most commonly cited deficiencies in 40-year recertification and SB 4-D milestone inspection reports. If a structural inspection identifies column spalling as a deficiency, repair is required to achieve compliance. Planet Construction FL has extensive experience executing column repairs as part of recertification scopes throughout Broward County.
A single column with moderate spalling on one or two faces typically takes 2–4 days from sounding and chipping through mortar application and cure. Columns with extensive four-face spalling or significant rebar corrosion take 4–7 days. We often work multiple columns simultaneously on larger projects to compress the overall project timeline.
We inspect, document, and propose — at no charge. Every column we touch comes back to spec, with full repair records.
