Warehouse & Commercial Slab Lifting · Sanibel, FL
Boat Storage & Marina Slab Lifting on Sanibel, FL
Settled slabs in a Sanibel or Captiva marina warehouse, boat club, or rebuilt boat-storage facility are not a standard industrial-floor problem. The loading is different, the post-Ian subgrade is different, and the vessels on the racks set the risk profile.
Settled slabs in a working facility cost money two ways: the repair, and the downtime. Most facility managers in Sanibel quote out a tear-out and re-pour and immediately stall on the operations math: a week of forklift lanes out of service, a dock door offline, racking pulled and reset.
Polyurethane injection lifts industrial slabs back to grade without demolition, without a re-pour, and without shutting down the lane. We work in zones around your operation: drill small ports, inject resin in stages, lift the slab in real time, patch the ports, hand the lane back. Forklifts roll on it the same shift.

Warehouse & Commercial Slab Lifting in Sanibel: the local picture
Sanibel is a barrier island west of Fort Myers, connected by the Sanibel Causeway. The island's character is set by strict conservation zoning and the unique east-west orientation that catches Gulf shells and storm energy from the south and west.
Sanibel and Captiva don't have traditional industrial warehousing, but they have working marina and boat-storage facilities, much of it rebuilt or in active reconstruction after Hurricane Ian. New slabs poured on disturbed post-Ian fill are showing early settlement; older slabs that survived the storm are sitting on subgrades that took heavy saltwater intrusion.
The honest cut
Replacement, or restoration?
Not every warehouse slab lifting job in Sanibel can be solved with injection. Some genuinely need replacement. Here's how we tell the difference on site.
When replacement is the right call
- Slab is fully fractured into multiple pieces
- Slab thickness or reinforcement is inadequate for the load class
- Subgrade has lost integrity beyond what injection can stabilize
- Facility is being repurposed and the new use requires different specs
When lifting solves the problem
- Settlement at dock thresholds creating trailer-to-floor mismatch
- Forklift lanes out of plane causing damage to load and equipment
- Trip hazards at expansion joints (OSHA exposure)
- Settling around column footings without structural cracking
- Dock leveler pit out of square
- Slab is intact but the subgrade has settled
The math
Replacement vs. restoration in Sanibel
Indicative ranges based on typical Sanibel projects. Final pricing depends on access, scope, and condition. Free written quotes after the on-site assessment.
Replacement
$12–$25/ square foot of affected area
- Timeline
- 1-3 weeks per zone, lane fully offline
- Disruption
- saw-cut, demolition, debris haul, re-pour, cure window before re-loading
Restoration polyurethane injection
$4–$10/ square foot of affected area
- Timeline
- hours per zone, lane back in service same shift
- Disruption
- small injection ports drilled and patched flush, no demolition, racking can stay in place

Sanibel notes
What we see on the ground in Sanibel
Sanibel and Captiva don’t have industrial warehousing in the traditional sense. What they have is a working marina and boat-storage market, much of it rebuilt or in active reconstruction after Hurricane Ian.
The post-Ian subgrade reality:
Storm surge across Sanibel and Captiva soaked and disturbed fill island-wide. New slabs poured during reconstruction are sitting on subgrades that received different compaction treatment depending on contractor and timeline; some are showing early settlement already. Older slabs that survived the storm are on subgrades that took significant saltwater intrusion and are still adjusting.
What we see on Sanibel boat-storage assessments:
- Newly rebuilt facilities: post-construction settlement showing up at 6-18 months as the subgrade compacts under operational loading
- Rack-leg drop in dry-stack facilities, putting racks out of plumb with vessels still loaded
- Drive-aisle settlement between racking
- Bay-door threshold drop at handler entry and exit
- Travel-lift pit settlement at launch and haul-out areas
- Older surviving facilities: ongoing settlement from saltwater-disturbed subgrades
Why injection works here when re-pour doesn’t:
Re-pouring a marina floor means emptying the racks at exactly the moment your operation can least afford the disruption, with a market that’s still short on temporary marina space post-Ian. Polyurethane injection lets us work zone-by-zone with vessels still in inventory. Close one drive aisle or one rack bay, lift, hand it back.
Honest read on the harder cases:
Some post-Ian slabs are sitting on fill so disturbed that injection won’t get a clean lift. We tell you so on the assessment. We don’t take a job we can’t do well, especially not with valuable vessels at stake.
Operations-aware scheduling: zone-by-zone, working around your handler schedule and member retrievals. Off-season windows preferred when feasible.
Insurance and bonding: Full GL, workers comp, bondable. Coverage appropriate for working inside facilities with high-value vessels in inventory. Insurance certificates, bonding documentation, and MSDS for the structural resin provided up front.
Common Sanibel/Captiva facility types we work in: marina warehouses, dry-stack storage, boat clubs, yacht maintenance buildings. ZIP 33957.

FAQ
Frequently asked questions
Can you work without shutting down our Sanibel facility?
That's the entire point of polyurethane injection in a working facility. We zone the work, scheduling around your operation. A typical Sanibel project closes a single forklift lane or a single dock for the duration of the injection (usually a few hours), then hands it back. The rest of the facility runs normally.
What's the load capacity of the cured resin?
The high-density structural resins we use for warehouse work carry compressive strength ratings supporting 6,000+ psf once cured. That's well above standard warehouse floor load class requirements. We'll match the resin spec to your floor's design load before we inject.
Will the patched injection ports affect forklift traffic?
No. Ports are 5/8-inch holes drilled through the slab and patched flush with a structural compound. The patched surface meets or exceeds the surrounding slab's wear and load characteristics.
Do you carry insurance and bonding for commercial work?
Yes. Full general liability, workers compensation, and bondable for Sanibel facility work. We provide insurance certificates and bonding documentation up front.
How fast can you mobilize for an OSHA-flagged trip hazard?
For active trip hazard exposure we mobilize within 48-72 hours in Sanibel. Most trip hazards are corrected within the same site visit. We can provide written documentation of the correction for your safety records.
