When columns start spalling or exposing rebar, your building's load path is at risk. We rebuild compromised columns to original spec — without tearing your property apart.
Structural column repair in Fort Lauderdale is one of the most urgent services we provide — and one property owners can't afford to postpone. Load-bearing columns are the literal backbone of every multi-story building, and South Florida's salt-air environment attacks them quietly for years before damage becomes visible. At Planet Construction FL, our licensed contractors restore structural columns to full load-bearing capacity using FDOT-approved materials and proven engineering methods — protecting your building, your occupants, and your liability.
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 spalling column isn't just ugly — it's a column whose rebar is corroding and whose load-carrying capacity is shrinking by the month. Once concrete starts breaking away, water reaches the steel faster, the rust expands, and more concrete pops off in a self-feeding cycle. Patching the surface without treating the rebar guarantees the problem returns within a year, often worse than before.
We start by exposing the corroded rebar, removing all rust, and treating the steel with corrosion inhibitors. Then we rebuild the column section using high-strength repair mortars or formed-and-poured concrete to match original specs. Finally, we apply a protective coating to slow future corrosion. Every column repair follows engineering guidance and is documented for your records.
Concrete columns often provide visible warning before failure becomes critical. Watch for horizontal or diagonal cracking along the column surface — early indicators of structural stress or expanding rebar beneath the concrete. Spalling (chunks of concrete breaking away from the surface) and rust staining running vertically down column faces are clear signs that embedded rebar has corroded and is pushing outward from within. Soft or hollow-sounding sections when tapped, visible rebar exposure, and staining at the base or near column caps all warrant immediate professional structural assessment. Don't mistake rust staining for a cosmetic issue — it is structural.

Chloride ions from ocean air penetrate the porous concrete matrix and reach the embedded steel reinforcement, triggering oxidation that causes rebar to expand in volume. As corroding steel expands, it fractures the surrounding concrete from the inside out, a process called chloride-induced spalling. Florida's year-round heat accelerates the chemical reaction. Columns in parking garages, ground-level applications, coastal-facing facades, and swimming pool areas are most vulnerable, but no multi-story structure in Broward County is truly immune over time.
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 restoration begins with a detailed structural assessment to determine the full extent of concrete deterioration and rebar corrosion. All compromised concrete is saw-cut and removed to expose the full damage zone — we never leave questionable material in place. Exposed rebar is treated with a corrosion inhibitor primer, and where rebar cross-section has been significantly reduced, supplemental steel is added. FDOT-approved repair mortars are applied in properly bonded lifts, fully restoring the column to its original profile and structural capacity. Final surface treatment — paint, protective coating, or waterproofing — is applied to defend against future deterioration and match the building's existing finish.

Standard column repair restores damaged concrete and treats corroded rebar. When columns also require structural capacity upgrades — to meet current Florida Building Code loads, support additional floors, or address significant rebar section loss — carbon fiber reinforced polymer (CFRP) wrapping is the superior solution. CFRP wrapping dramatically increases a column's shear and compressive capacity, adds no meaningful weight, installs efficiently, and — critically — is completely non-corrosive, meaning it won't repeat the corrosion cycle that caused the original damage. Planet Construction FL applies CFRP wrapping per engineering specifications on projects where load demands or code requirements call for it.

Structural column repair in Fort Lauderdale requires a building permit and, in most cases, involves coordination with the structural engineer of record. Planet Construction FL works directly alongside licensed structural engineers throughout the repair process, ensuring all work meets Florida Building Code requirements and is properly documented for building department approval. For properties undergoing 40-year recertification or SB 4-D milestone inspections, we execute the full repair scope identified in the engineering report and supply the required documentation to close out structural deficiency findings — so your building passes inspection without delay or re-inspection cycles.

Visible spalling, rust staining, cracking, or exposed rebar are the clearest signs. A hollow sound when tapping the column surface can indicate delamination beneath. If you see any of these warning signs, schedule a professional structural assessment immediately — early-stage column damage is significantly less expensive to repair than deterioration that has reached the rebar or load-bearing core.
Column damage from sudden events (pipe bursts, vehicle impact) may be covered. Gradual corrosion deterioration typically is not covered under standard property policies. Planet Construction FL provides detailed written documentation for any insurance submission, and our assessment reports are prepared to meet the documentation standards that insurance adjusters and attorneys require.
A single column with moderate spalling and rebar corrosion typically takes 2–5 days from preparation through mortar application and curing. Complex repairs or CFRP wrapping add 1–2 days. Where project layout allows, we work multiple columns simultaneously to compress overall project timelines.
In most cases, no. We maintain safety exclusion barriers around active work areas and schedule the noisiest operations — chipping, saw-cutting — during standard business hours. For parking garage column repairs, we may temporarily redirect vehicle traffic around the active zone. All access requirements are clearly outlined before work begins.
