Cracks, settling, and uneven slabs in Florida usually trace back to soil, water, or rebar issues. We diagnose the real cause and stabilize the foundation for the long haul.
Foundation repair in Fort Lauderdale is among the most consequential structural repairs a property owner will ever face — and South Florida's geology makes foundation problems more common here than in most parts of the country. Fort Lauderdale sits on sandy, highly permeable soil with a shallow water table that shifts with rainfall, drought, and seasonal groundwater changes. These conditions create foundation settlement, cracking, and moisture intrusion at rates that surprise most property owners. At Planet Construction FL, we diagnose foundation problems accurately and execute repairs that address the root cause — not just the visible symptoms.
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.
Foundation problems in Florida usually trace back to soil movement, water intrusion, or rebar corrosion deep in the slab. Cracks in walls, sticking doors, uneven floors, and visible slab cracks are all symptoms of something happening below. Cosmetic patches do nothing for the underlying cause, which keeps moving, settling, or corroding until the damage becomes structural.
We diagnose first — soil assessment, water intrusion sources, slab inspection, and rebar evaluation — so we're solving the actual cause, not just the symptom. Then we apply the right combination of underpinning, slab repair, drainage correction, and waterproofing for your specific situation. Every repair is documented and engineered for long-term stability.
Foundation problems announce themselves throughout a building before they reach a critical stage. Diagonal cracks running from the corners of windows and doors are a classic settlement indicator. Doors and windows that suddenly stick or no longer close properly signal that the building frame has shifted relative to its foundation. Horizontal cracks in masonry block foundation walls indicate lateral earth or hydrostatic pressure. Floor slabs that slope, crack in tile finishes, or feel springy in localized areas point to slab settlement or subgrade instability. Water infiltration through foundation walls or under slabs during and after rain events indicates drainage failure or waterproofing breakdown at the foundation level. Any combination of these signs warrants a professional foundation assessment immediately.

Sandy soil with low cohesion settles and shifts under load and with groundwater changes — particularly in areas near the Intracoastal, canals, or coastal zones with fluctuating water tables. Organic soil and peat layers — common in low-lying South Florida areas — compress under building loads over time, causing progressive settlement. Erosion from irrigation, storm drainage, and plumbing leaks beneath slabs undermines support and creates voids that cause sudden slab settlement. Unlike northern climates where frost heave is the primary driver, South Florida foundation movement is driven by soil moisture cycling, erosion, and subsidence — all requiring different diagnostic and repair approaches.
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.
The right foundation repair method depends entirely on the type and cause of movement. Slab lifting — using expanding polyurethane foam injected beneath the slab to fill voids and raise settled sections — is effective for ground-level slabs with subgrade voids. Deep foundation underpinning with driven steel piers or helical piers transfers the building load to deeper, competent strata when the soil at foundation depth is inadequate. Foundation wall crack repair uses epoxy injection for structural bonding of dormant cracks and carbon fiber straps for bowing or failing walls. Drainage correction — regrade, drain installation, waterproofing — addresses the moisture causes that drive soil instability. We specify the correct method or combination of methods for each specific condition.

Foundation waterproofing in South Florida is not optional — it is a necessity for any foundation exposed to the high water table and intense rainfall of Broward County. Negative-side waterproofing applied from the interior uses crystalline compounds that penetrate the concrete matrix and form water-blocking crystals throughout the wall thickness. Positive-side waterproofing applied from the exterior uses sheet or liquid-applied membrane systems that prevent water from reaching the concrete entirely. For foundations with chronic water infiltration, we assess whether positive-side access is feasible and specify the most effective waterproofing approach for the condition. Both approaches are installed with proper drainage details to relieve hydrostatic pressure rather than simply resisting it.

Foundation issues are inherently progressive — they do not resolve on their own and they worsen over time. Early-stage settlement or cracking is far less expensive to address than advanced foundation failure. If you're seeing signs of foundation movement, schedule an inspection as soon as possible. Structural deterioration is not something to watch and wait on in South Florida's soil conditions.
Most standard Florida homeowner's policies exclude gradual settlement and soil movement. Sudden damage from a covered peril — like a plumbing leak that erodes soil beneath the slab — may be partially covered. We provide detailed assessment documentation and repair scope reports that support insurance submissions and give your claim the best chance of a fair review.
Slab lifting with polyurethane foam for a typical residential slab can often be completed in 1–2 days. Underpinning projects installing driven piers typically take 3–10 days depending on the number of pier locations. Foundation wall crack repair takes 2–5 days. Timeline is confirmed after our structural assessment and scope development.
For moderate to significant foundation issues — visible structural cracking, measurable differential settlement, or foundation wall failure — yes, a structural engineer's assessment is strongly recommended and in many cases required by the building department for permit issuance. Planet Construction FL works with licensed structural engineers throughout the repair process and can recommend firms with South Florida foundation experience.
