A sunken garage slab causes door binding, water pooling at the back wall, and structural concerns where the slab meets the foundation wall. We can lift garage floors in a single day with no demolition, no jackhammers, and no week-long curing.
Common Garage Slab Problems We Fix
- Garage door scrapes the slab (settlement at the front)
- Water pools toward the back wall (settlement at the back)
- Cracks running across the slab as it pulls apart
- Visible gap between the slab and the foundation wall
- Tools and stored items rolling toward the back
Why Garage Slabs Settle
Iowa garage slabs are particularly vulnerable because they’re often poured on uncompacted fill from foundation excavation. As that fill compacts over years, the slab loses support. Add Iowa freeze-thaw and you get rapid settlement.
The slab itself is usually fine — it’s the soil underneath that has voids and compacted zones that need filling.
Garage Slab Lifting Cost in Bondurant
Pricing depends on slab size (1-car vs. 2-car vs. 3-car), how much settlement needs correcting, and access from the driveway side.
Compare to slab replacement: typically $8,000–$15,000, plus storing all your garage contents for 1–2 weeks.
We provide free, on-site, no-obligation estimates with the exact cost for your specific job.
How Garage Slab Lifting Works
- Clear the garage of vehicles and stored items (you handle this)
- We drill 5/8″ holes in a pattern that matches the settlement
- Inject polyurethane foam under the slab
- Slab lifts back to original elevation
- Verify that the garage door has proper clearance (usually 1/2″ gap when closed)
- Patch holes with color-matched cement
- You drive back in within 1 hour
Frequently Asked Questions
My garage door scrapes the floor. Will lifting fix that?
Yes — once the slab is lifted to grade, the door will have its original clearance. We verify the gap before completing the job.
Can you fix a sloping garage floor that’s pulling away from the foundation wall?
Yes, this is one of the most common issues we see. We lift the slab back into contact with the foundation and fill any visible gap.
What if my garage has heated floors or radiant tubing?
Tell us during the estimate. We’ve worked around radiant systems before. We carefully avoid drill paths that could hit tubing.
How long until I can park in there again?
1 hour after the foam cures.
Will the lift hold the weight of my truck or SUV?
Yes. Polyurethane foam is rated for over 7,000 PSI compressive strength — far more than residential vehicles will ever apply.
