Foundation Repair in Miami & South Florida.
Engineered foundation repair for South Florida — diagnosed, designed, permitted, and installed under one licensed engineer of record
Why foundation repair matters in South Florida
Foundation movement in South Florida is rarely the soil’s fault alone. The region’s geology — shallow oolitic limestone, organic-rich fill, former wetland reclaimed during the post-war building boom, dredged-canal-spoil backfill — creates a built environment where foundation behavior is sensitive to drainage, vegetation, water-table fluctuation, and the integrity of the seawall holding back the canal water table itself.
The visible symptoms are familiar: stair-step cracking in CMU walls, diagonal cracks at door and window corners, hairline cracks in stucco that grow over time, doors that stop closing, floors that pitch toward the seawall, slabs that crack along columns and walls. These are not always foundation problems — sometimes they are framing, drainage, or expansion-joint issues — and selling foundation repair without a diagnostic basis is malpractice.
Souffront does not start with a repair scope. Souffront starts with a Florida-licensed structural engineer’s assessment that confirms the diagnosis before any solution is specified. Where remedial foundation work is justified, Souffront engineers, permits, installs, and verifies the system — all under one engineer of record.
The repair process
1. Structural assessment. Engineer walkthrough, crack mapping, floor-elevation survey, exterior drainage inspection, and review of historic drawings where available.
2. Diagnosis. If indications warrant, geotechnical investigation (soil borings, water-table determination), structural calculations, and root-cause confirmation before any repair scope is written.
3. Engineered scope. Sealed repair drawings specifying the right system — helical pier, push pier, underpinning, soil stabilization — sized to the load and depth required.
4. Permitting. Building-department permit with sealed engineering plans.
5. Installation. In-house crews supervised by the engineer of record. Vibration-free hydraulic installation. Real-time torque or pressure monitoring.
6. Verification & closeout. Capacity verification by torque correlation or load test. Sealed as-built drawings and AHJ closeout package.

Repair systems we install
Helical piers. Hydraulically advanced galvanized steel shafts with helical bearing plates that transfer load through soft, compressible, or saturated soils to a deeper, stable bearing stratum. Vibration-free installation. Verified capacity by torque correlation. Suitable for both remedial use under existing foundations and new-construction applications.
Push (resistance) piers. For heavier structures, push piers transfer load through hydraulically driven steel sections directly underneath the existing footing. Capacity is verified by hydraulic pressure during installation. Common in mid-rise and commercial applications where helical capacity isn’t sufficient.
Underpinning. Where the existing foundation is sound but bearing has been lost beneath it, Souffront extends the foundation to a deeper bearing stratum using sectional underpinning techniques specified by the engineer of record.
Slab repair. Cracked or settled slabs adjacent to columns and walls are repaired with structural epoxy injection, polyurethane lift, or sectional replacement depending on the engineering scope.
Soil stabilization. Compaction grouting, permeation grouting, and chemical grouting where the soil itself has lost bearing capacity — often the right answer when the foundation is intact but the supporting soil has migrated, washed out, or developed voids.
The deliverable
Every foundation repair project closes with sealed engineering drawings, the as-built record, capacity verification documentation, and a closeout letter from the Florida-licensed structural engineer of record. The package satisfies building-department, insurance, and real-estate transaction requirements.
When to engage us
- Stair-step cracks in CMU walls, diagonal cracks at door/window corners, or stucco cracks wider than 1/8 inch
- Doors that stop closing or floors that have pitched noticeably
- Visible settlement adjacent to a seawall or pool deck

Pricing
Foundation repair is priced fixed-fee against the engineered scope, quoted before mobilization. The fee is driven by pier count, depth, system selection, access conditions, and permitting requirements. There is no hourly billing.
For HOAs and commercial portfolios, master agreements offer locked unit pricing across multi-property programs with continuous engineer of record.

Frequently asked questions
Minor crack sealing on otherwise sound foundations runs $300–$800. Pier-based stabilization typically runs $1,000–$3,000 per pier, with the total driven by pier count, depth, and access. Whole-house programs commonly land between $7,000 and $25,000; larger structural rehabilitations on settled mid-rise or commercial structures run higher. The diagnostic engineering comes first — we do not write a repair scope without confirming the cause.
Width, location, and orientation matter. Hairline shrinkage cracks under 1/16 inch in stucco are usually cosmetic. Diagonal cracks at door and window corners, stair-step cracks in CMU walls, horizontal cracks anywhere in a foundation wall, and any crack wider than 1/8 inch deserves a structural assessment. So does any crack that widens visibly over time — movement matters more than width on day one.
Stair-step cracking in CMU or block walls; diagonal cracks at door and window corners; stucco cracks wider than 1/8 inch; doors and windows that no longer close properly; floors that have pitched noticeably (often toward a seawall or canal); slab cracks running along columns or walls; visible separation between the slab and adjacent fixed elements; sinkholes or surface depressions in the yard. Any one of these warrants an engineering assessment before you spend money on a repair scope.
The engineer of record decides, against the load and the soil. Helical piers are typically the right call for lighter residential structures, additions, new construction, and tight-access conditions — capacity is verified by installation torque. Push piers are typically the right call for heavier mid-rise and commercial structures where the building weight itself can be used as installation reaction. Neither is "better" in isolation; both are correct on their own load and soil profile.
In most residential cases, yes. Helical and push-pier installation is staged from the exterior of the structure, vibration-free, and progresses one bay at a time without significant disruption inside the house. Interior slab work (epoxy injection, polyurethane lift, sectional slab replacement) is the only scope that occasionally requires temporary displacement, and we sequence it to minimize that window.
When the diagnosis is correct and the intervention is properly engineered, yes. Helical and push piers transfer load to a deep, stable bearing stratum — bypassing the soft, compressible, or saturated soil that was driving the movement. The wrong diagnosis is the most common reason a foundation "repair" doesn't hold, which is why Souffront leads every project with a Florida-licensed structural engineer and confirms the cause before specifying the system.
Sometimes — and it depends on the cause. Foundation damage from a covered peril (sinkhole activity in counties with sinkhole coverage, a documented water-main rupture, certain storm events) may be covered. Foundation movement from normal soil consolidation, gradual settlement, or poor original construction is typically excluded as wear-and-tear. The engineer-sealed report Souffront produces is the documentation carriers require to evaluate the claim.
