Commercial Foundation Repair
Foundation Masters provides engineer led commercial foundation repair throughout Florida for settlement, slab and panel movement, void formation, concrete deterioration, drainage failure and structural instability.
Florida is not one geotechnical market. A warehouse on the Gulf coast, a retail center on reclaimed mine land, an office building over karst and a condominium on the Atlantic Coastal Ridge have four different problems, even when the crack on the wall looks identical.
We are a licensed Florida engineering firm and a structural repair contractor in the same company, working statewide. The investigation, the sealed design and the installation come from one accountable party rather than three.
Contractor Execution With Engineering Behind It
Foundation Masters is a licensed Florida engineering firm, CA# 30969, and a structural repair contractor. We work statewide on office and medical buildings, retail centers, warehouse and distribution facilities, port and industrial property, hotels, restaurants, multifamily and condominium buildings, and municipal structures.
The work is usually settlement, differential movement across a large slab area, void formation, panel and joint displacement, concrete deterioration, drainage and hydrostatic pressure, or suspected sinkhole activity.
The difference is not just what we install. The difference is how we decide what to install, and who signs it. We pair contractor work with in-house structural engineering, civil engineering, and geotechnical engineering.
For heavy manufacturing and plant work, see industrial foundation repair. For residential, see the Florida foundation repair hub.
- Licensed Florida engineering firm, CA# 30969, with contractor execution in the same company, so nobody is waiting on a third party for a sealed drawing.
- Sealed structural drawings, calculations and written reports prepared for permitting, lenders and insurers rather than as a sales attachment.
- Soil borings and subsurface investigation, because on a commercial footprint the bearing profile drives the entire design.
- Statewide coverage with local knowledge, so the design reflects the ground in that market rather than a national playbook.
- Deep foundation capability in house, including pipe pile, pile driving, sheet piling, drilled shafts and micropiles.
- Repairs phased around occupancy, trading hours, dock operations and tenant access.
- Documentation suitable for due diligence, capital planning and reserve budgeting rather than just a repair price.
Why a Statewide Firm Has to Know More Than One Answer
Most commercial foundation contractors sell a system. They arrive with one product, and the diagnosis tends to arrive at that product. That works in a market with uniform ground. Florida is not that market, and the differences are large enough to change what a repair has to do.
On the Gulf coast, salt is the driver. Chlorides reach reinforcement through salt air, splash and brackish groundwater, corroding steel expands, and concrete spalls off from the inside. Alongside it sits made ground, because port and waterfront development created land as it dredged channels, and Hillsborough falls inside the stretch of Florida with the highest concentration of sinkhole activity in the state.
Through Central Florida the controlling factor is karst. Limestone dissolves, voids develop, and where the confining layer above is partial rather than absent, the ground can bridge over a cavity and then fail suddenly. That is not theoretical here. In May 1981 an acre wide sinkhole in Winter Park took a house, a swimming pool, part of a car dealership and parts of several businesses.
Across the inland belt the issue is made ground of a different kind. Polk County sits in Bone Valley, where draglines strip fifteen to thirty feet of overburden into spoil piles, waste clay is pumped into diked settling areas, and sand tailings go back into the pits as reclamation fill. Reclamation was only voluntary in Florida before 1975. Further east, in the Kissimmee basin, drained wetland and old lake margin left behind organic muck and peat that keep compressing under load for decades.
And in South Florida the geology changes again. The Miami Limestone, an oolitic and bryozoan limestone, surfaces along the Atlantic Coastal Ridge through Palm Beach, Broward and Miami-Dade. Beneath it the Biscayne Aquifer is unconfined, meaning the top of the aquifer is effectively the water table, in highly permeable limestone. Excavation, dewatering and foundation design all have to account for that.
Four regions, four mechanisms, and a commercial building can present the same symptom in any of them. That is why we investigate before we price, and why the regional pages below are not the same page with the city name swapped.
Assessment & Documentation
Elevation surveys, crack and delamination mapping, subsurface investigation and written engineering opinion, in a form a lender, insurer or board can act on.
Deep Foundation Support
Helical piers, push piers, micropiles, pipe pile, driven and sheet piling and drilled shafts, sized to commercial loads and taken to competent bearing.
Slab, Void & Concrete Work
Compaction and pressure grouting, slab lifting and void filling, plus concrete repair and reinforcement for members that have deteriorated or moved.
In Florida, Structural Condition Now Has Deadlines.
Florida law requires a milestone inspection of condominium and cooperative buildings three habitable stories or more in height, by 31 December of the year the building reaches 30 years old measured from its certificate of occupancy, and every ten years after that. A local enforcement agency may require it at 25 years where environmental conditions such as proximity to salt water justify the earlier date, which matters on both coasts.
Phase One is a visual examination by a licensed Florida engineer or architect. Phase Two, with testing, is triggered only where substantial structural deterioration is identified. The association has 45 days from receiving the report to distribute the summary to unit owners, post it conspicuously, and publish it where a website is required.
Running alongside it is the structural integrity reserve study, required at least every ten years for residential condominium buildings three habitable stories or higher, covering the roof, structural members, fireproofing and fire protection, plumbing, electrical, waterproofing and exterior painting, windows and doors, and any other item with a deferred cost over 25,000 dollars. Since budgets adopted after 31 December 2024, associations required to obtain one can no longer vote to waive or reduce reserves for the components it identifies.
The practical effect is that a structural finding now converts into a funding obligation. Confirm which trigger applies to your building with your local building official and your association counsel, then get the engineering done early enough that you are choosing a repair rather than reacting to a finding.
Where We Work and What Changes
Statewide coverage, with a regional page for the markets where the ground behaves differently enough to need its own answer.
Tampa Bay & the Gulf Coast
Hillsborough, Pinellas, Pasco, Manatee, Sarasota and south along the coast, including port, industrial and waterfront commercial property.
Chloride driven corrosion, dredge fill, seawalls and bulkheads, and the highest sinkhole concentration in the state. See commercial foundation repair Tampa.
Central Florida
Orange, Osceola and Seminole counties and the I-4 corridor, including the hospitality, retail and distribution property that fills it.
Karst limestone, void formation, organic soils in the Kissimmee basin and heavy new construction on fill. See commercial foundation repair Orlando.
South Florida
Miami-Dade, Broward and Palm Beach, including high rise, multifamily, hospitality and coastal commercial property.
Miami Limestone at or near the surface, an unconfined aquifer with the water table close behind it, salt exposure and dense urban access. See commercial foundation repair Miami.
Inland & North Florida
Polk County and the Bone Valley belt, the Highlands and Lake ridge country, and north through Jacksonville and the St. Johns corridor.
Made ground from mining, clay settling areas, organic soils, and a very different water and soil regime from the coast. See Jacksonville.
Commercial Warning Signs
- Slab cracking or joint separation that is widening, or weathered cracks reopening after repair.
- Floor levelness out of tolerance for racking, equipment or a tenant fit out.
- Stair step cracking in block or masonry, or displacement at a panel joint.
- Storefront doors or glazing binding, which is often the first thing a tenant reports.
- Dock aprons, truck courts or drive aisles dropping in the wheel paths.
- Pavement or sidewalk slabs settling at the edge, which usually means a void below.
- A circular or oval depression appearing in a lot, a landscape island or a retention area.
- Rust staining, spalling concrete or exposed reinforcement. See steel corrosion.
- Concrete that sounds hollow when sounded, which usually means delamination before it becomes a spall.
- Standing water that does not clear after rain, or efflorescence on interior masonry.
- Movement that began or worsened during adjacent construction. See construction vibration damage.
- Anything a milestone inspection, reserve study or lender due diligence report has flagged for follow up.
A depression in the ground and spalling that exposes reinforcement are the two to act on immediately. Everything else is better documented early than argued about later.

Common Questions About Commercial Foundation Repair
How do I know if my commercial building needs foundation repair?
Common indicators include floors out of level or out of tolerance for equipment, stair step or horizontal cracking in masonry, doors and glazing binding, slab joint separation, pavement or dock settlement, spalling concrete or exposed reinforcement, and a depression appearing anywhere on the site. An engineering inspection confirms whether those are cosmetic, active, or structural, and what is driving them.
Why does the region matter so much in Florida?
Because the ground changes completely across the state. The Gulf coast brings salt driven corrosion and dredge fill. Central Florida brings karst limestone and void formation. The inland belt brings made ground from phosphate mining and organic muck from drained wetland. South Florida brings the Miami Limestone at or near the surface over an unconfined aquifer. The same symptom can have four different causes depending on where the building sits, which is why a single system sold statewide gets it wrong somewhere.
Do you provide signed and sealed repair plans for permitting?
Yes. Foundation Masters is a licensed Florida engineering firm, CA# 30969, and our engineer of record prepares and seals drawings, calculations and reports for submittal to the relevant municipality or county. Because the engineering and the contracting sit in the same company, the design and the installation do not have to be reconciled between two firms after the fact.
What repair methods work best for large commercial buildings?
Method follows loads and ground. Helical piers, push piers, micropiles, pipe pile, driven and sheet piling, concrete piling and drilled shafts for load transfer, compaction and pressure grouting for loose material and voids, slab lifting where elevation can be recovered, and carbon fiber or steel reinforcement for members that need strengthening in place. On most commercial work the governing question is depth to competent bearing.
Can you work without closing the building?
In most cases yes. We phase the work around occupancy, trading hours, dock operations and tenant access, and we sequence so that the areas taken out of service are the smallest and the shortest lived they can be. On a parking structure that usually means working deck by deck or bay by bay. That is planned at the design stage rather than negotiated on site.
How long does a commercial project take?
Smaller stabilization and grouting projects can finish in days. Deep underpinning, extensive concrete repair or phased work across an occupied building can run several weeks or longer. Permitting, engineering scope, access and phasing requirements usually influence the schedule more than the installation itself does.
Is commercial foundation damage covered by insurance?
It depends on the cause and on the specific policy. Gradual settlement from age, soil conditions or deferred maintenance is commonly excluded. Damage arising from a sudden and identifiable event may be treated differently. Coverage is a question for your policy and your carrier, not for a contractor, and we do not advise on it. What we provide is the engineering documentation that establishes cause, which is what any claim conversation ultimately turns on.
What is a milestone inspection and does it apply to us?
Florida law requires a milestone inspection of condominium and cooperative buildings three habitable stories or more in height, due by 31 December of the year the building reaches 30 years old measured from the certificate of occupancy, then every ten years. A local enforcement agency may require it at 25 years where environmental conditions such as proximity to salt water justify it. Whether and when it applies to your specific building should be confirmed with your local building official and your association counsel.
What is a structural integrity reserve study?
It is a study required at least every ten years for residential condominium buildings three habitable stories or higher, covering the roof, structural members, fireproofing and fire protection, plumbing, electrical, waterproofing and exterior painting, windows and doors, and any other item with a deferred maintenance or replacement cost over 25,000 dollars. For budgets adopted after 31 December 2024, a unit owner controlled association required to obtain one may not vote to provide no reserves or reduced reserves for the items it identifies.
Do you perform soil borings on commercial sites?
Yes, and on a commercial footprint we usually need more than one location. Borings establish fill depth and character, where competent bearing begins, whether soft or organic material is present, and whether the profile varies across the building. On a large slab, variation across the footprint is frequently the whole explanation for differential movement.
Can you support acquisition or refinance due diligence?
Yes. We provide structural assessment and written engineering opinion suitable for due diligence, capital planning and reserve budgeting, including scope and sequencing for identified work. Where a condition report or lender review has flagged something, we can evaluate it and say plainly whether it is a defect that needs correcting or a condition that needs monitoring.
Why hire a Florida licensed engineering firm rather than a repair company?
Because a repair that has to be permitted, inspected and defended needs an engineer of record behind it. Engineer designed repairs are sized to the actual loads and ground conditions, they carry sealed documentation that a building official, lender or insurer will accept, and they are far harder to challenge later. A firm that only installs one product has an obvious incentive in the diagnosis.
Are your foundation systems warrantied?
Yes. Helical pier systems include a 25 year transferable warranty, and concrete or timber piling systems include a 15 year warranty. Because many components are designed and fabricated in house, we keep quality control across engineering, manufacture and installation.
What do commercial foundation repairs cost?
Costs vary with the structural conditions, the repair method, depth to competent bearing, the extent of any concrete deterioration, the size of the affected area, access, phasing requirements and engineering scope. Depth and access are usually the two largest drivers, which is why we investigate before we price. Foundation Masters provides detailed repair proposals following inspection.
Solutions We Commonly Use
After an on site structural and geotechnical evaluation, we develop a prioritized repair strategy based on the structure, loading, fill depth and character, groundwater and exposure, drainage, occupancy constraints and long term performance requirements. Depending on the property, that may include:
- Helical piers to stabilize and lift settled foundations and slabs.
- Push piers for deeper load transfer on heavier structures.
- Micropiles where access is restricted or loads are concentrated.
- Pipe pile, concrete piling, timber piling and driven piling for deep support.
- Sheet piling and drilled shafts for waterfront and heavy load conditions.
- Compaction grouting to densify loose fill beneath large slab areas.
- Pressure grouting and slab lifting to fill voids and recover elevation.
- Concrete repair for spalling and delamination, with carbon fiber and steel reinforcement.
- Retaining walls, drainage and pavement correction across the site.
Helical pier installations include a 25 year transferable warranty. Concrete and timber piling systems include a 15 year warranty. Full terms on our warranties page.
