TL;DR: Polyjacking lifts sunken driveways in Wilmington using lightweight polyurethane foam injection - typically costing $500–$2,500 versus full replacement costs of $4,000–$10,000+. The process takes 1–3 hours, and your driveway is usable the same day. Here in Wilmington's sandy coastal soil, polyjacking is often the smarter choice than mudjacking because the lightweight foam won't overload an already-unstable sub-base.

What Is Polyjacking and How Does It Level a Driveway?

Polyjacking - also called polyurethane foam injection or foam jacking - is a concrete repair method that lifts and levels sunken slabs by injecting expanding polyurethane foam beneath the concrete. The foam fills voids created by soil erosion, compaction, or settling, then hardens into a lightweight, moisture-resistant support structure.

Here's the basic process: a contractor drills small 5/8-inch holes in a grid pattern across the sunken section, then injects two-part polyurethane foam through each hole. The foam expands and fills the void space beneath the slab, gradually lifting it back to level. The entire injection phase takes 15–30 minutes to cure, and the concrete reaches full load-bearing capacity within 30 minutes - meaning you can drive on your driveway the same day the work is done.

The appeal is straightforward: polyjacking is faster, cheaper, and less disruptive than tearing out and replacing the entire driveway. (Noaa.gov) (Dot.gov) The injection holes are tiny compared to mudjacking's 1–2 inch openings, and when sealed properly, they're nearly invisible. For homeowners in Wilmington dealing with a sunken driveway section, this technology offers a practical middle ground between accepting the hazard and spending $6,000+ on a full replacement.

Why Do Driveways Sink in Wilmington NC?

Our community sits on the Cape Fear Coastal Plain, a geological region dominated by sandy, poorly consolidated soils with high organic content. Unlike clay-heavy soils inland, these sandy layers don't hold their shape well under the weight of concrete and vehicle traffic - especially when water moves through them.

Wilmington's climate accelerates the problem. Heavy rainfall, which averages over 55 inches per year in the Wilmington area, percolates through the sandy sub-base beneath your driveway, washing away fine particles and creating voids. Heavy summer storms and tropical systems dump water quickly, and our high water table means the soil stays saturated for extended periods. Over time, these voids grow larger, and the concrete slab loses support and sinks.

Tree roots compound the issue in established neighborhoods. Mature live oaks and pines throughout Wilmington's older residential areas - Midtown, Forest Hills, and similar districts - send roots beneath driveways searching for moisture. As roots decay after being cut or damaged, they leave hollow spaces that collapse under load.

Unlike inland North Carolina cities, Wilmington experiences minimal freeze-thaw cycling (fewer than five cycles annually), so frost heave isn't the primary culprit here. Instead, erosion and moisture-driven settling dominate. This distinction matters when choosing a repair method: techniques designed for freeze-thaw climates may not address Wilmington's real problem.

How Much Does Polyjacking a Driveway Cost in Wilmington?

Polyjacking typically costs between $500 and $2,500 for a residential driveway, depending on the size of the sunken area, the amount of foam required, and soil conditions. Most standard jobs fall in the $800–$1,500 range.

Contractors usually price polyjacking per section or per hole. A typical sunken panel (roughly 10 × 12 feet) might require 4–6 injection points and cost $300–$600. A two-car driveway with three sunken sections would run approximately $900–$1,400 - a savings of roughly $5,000 compared to full concrete replacement.

Several factors affect the final price:

• Severity of settling: A slab that's dropped 2 inches requires less foam than one that's dropped 4 inches.
• Soil conditions: Sandy soils like ours in Wilmington may require more foam volume to achieve stable support.
• Accessibility: If the driveway is blocked by landscaping or parked vehicles, setup takes longer.
• Number of cracks: Existing cracks may need to be sealed before or after foam injection to prevent foam escape.

The cost-per-section approach makes polyjacking flexible: you can repair just the worst areas now and address others later, spreading the expense over time. That's not an option with full replacement.

Polyjacking vs. Mudjacking vs. Replacement: Which Is Right for Your Driveway?

All three methods lift concrete, but they work differently and suit different situations. Polyurethane foam is lightweight and moisture-resistant, making it superior to mudjacking's heavier slurry in unstable soils. Here's how they compare:

Polyjacking wins when: You need a fast repair in sandy coastal soil. The lightweight foam won't overload Wilmington's unstable sub-base the way mudjacking's heavy slurry can. You also get same-day use and nearly invisible repair holes. It's the premium choice for homeowners who want durability and minimal disruption.

Mudjacking may suffice when: Your budget is tight and you're willing to accept a longer cure time. The heavier slurry can work for larger slabs, though in Wilmington's sandy soils, it risks re-settling faster because it doesn't address the underlying weakness. Mudjacking also leaves larger, more visible patched holes.

Replacement is necessary when: Your concrete is severely cracked (wider than 1/2 inch), has multiple fracture planes, or has heaved more than 4 inches. Polyjacking lifts and levels but doesn't repair structural damage. If the slab is broken, replacement is the only real solution.

For most Wilmington homeowners with a sunken but structurally sound driveway, polyjacking is the sweet spot: it costs far less than replacement, works better than mudjacking in our sandy soils, and delivers results the same day.

What Does the Polyjacking Process Look Like on Your Driveway?

Here's what to expect when a polyjacking crew arrives at your home:

1. Assessment (15–30 minutes) The contractor inspects the driveway, identifies sunken sections, and checks for cracks or structural damage. They'll also ask about drainage issues - water pooling, gutters, or grading problems - because addressing these alongside the repair is critical for long-term success.

2. Drilling (30–45 minutes) Using a handheld drill, the crew creates 5/8-inch holes in a grid pattern across the sunken area. Holes are typically spaced 3–4 feet apart. Drilling is loud but brief and creates minimal dust with proper equipment.

3. Foam injection (30–60 minutes) The contractor connects injection hoses to each hole and begins pumping two-part polyurethane foam. You'll see the sunken section gradually rise as the foam expands beneath it. The crew monitors the lift in real time, stopping when the slab reaches level.

4. Leveling verification (10–15 minutes) Once injection is complete, the contractor checks the slab with a level to confirm it's even. Minor adjustments are made if needed.

5. Hole sealing (15–30 minutes) The small injection holes are filled with concrete patching compound and smoothed flush with the surface. When done correctly, these patches are barely noticeable.

Total time: Most residential driveway jobs take 1–3 hours from start to finish. You can drive on the repaired section within 30 minutes of completion, though waiting a few hours allows the patching compound to fully cure.

The process is clean, quiet compared to jackhammering, and causes minimal disruption to your yard or neighbors.

Is Polyjacking a Long-Term Fix for Wilmington Driveways?

Polyjacking delivers a durable repair - typically 10+ years or longer - but only if the underlying cause of settling is addressed. This is the critical point for homeowners in Wilmington.

The polyurethane foam itself is excellent. It's moisture-resistant, chemically inert after cure, and unaffected by Wilmington's high humidity or coastal salt air. The foam won't degrade, absorb water, or lose strength over time. The problem isn't the foam; it's the soil beneath it.

If water continues to erode the sub-base after polyjacking, new voids will form and the slab will settle again - typically within 3–7 years. This is why drainage correction is non-negotiable. Before or alongside polyjacking, you need to:

• Ensure gutters and downspouts direct water away from the driveway
• Grade the yard so water doesn't pool near the slab
• Install or repair French drains if water is chronically present
• Address any tree root issues that contributed to the original settling

Here in Wilmington, where we receive over 55 inches of annual rainfall, water management is the deciding factor for repair longevity. A contractor worth hiring will assess your drainage situation and recommend fixes alongside the polyjacking. Professional Concrete Lifting & Leveling takes this approach - they don't just lift the slab; they identify and help you address the root cause so the repair lasts.

When drainage is corrected, polyjacking is a genuinely long-term solution. When it's ignored, you're likely to need retreatment within a few years.

Polyjacking vs. Mudjacking vs. Replacement: Which Is Right for Your Driveway?

All three methods lift concrete, but they work differently and suit different situations. Polyurethane foam is lightweight and moisture-resistant, making it superior to mudjacking's heavier slurry in unstable soils. Polyjacking typically lasts 10 to 20 years or more, while mudjacking typically lasts 2 to 5 years — the cement slurry mixture is susceptible to erosion, especially in areas with poor drainage, and the heavier material can compress unstable soil over time, causing the concrete to resettle.

What Does the Polyjacking Process Look Like on Your Driveway?

Here's what to expect when a polyjacking crew arrives at your home: Assessment of the driveway and drainage issues, drilling of 5/8-inch holes in a grid pattern, injection of two-part polyurethane foam, leveling verification, and hole sealing with concrete patching compound. Most residential driveway jobs take 1–3 hours from start to finish.

Is Polyjacking a Long-Term Fix for Wilmington Driveways?

Polyjacking delivers a durable repair - typically 10+ years or longer - but only if the underlying cause of settling is addressed. The polyurethane foam is moisture-resistant and won't degrade over time. The limiting factor is whether water continues to erode the sub-base. Drainage correction is critical for long-term success.

How much does polyjacking a driveway cost in Wilmington NC?

Polyjacking typically costs $500–$2,500 for a residential driveway, with most jobs in the $800–$1,500 range. A standard two-car driveway with three sunken sections usually runs $900–$1,400.

How long does polyjacking last on a Wilmington driveway?

Polyjacking typically lasts 10+ years when the underlying drainage cause is addressed. Without drainage correction, settling may recur within 3–7 years.

Is polyjacking better than mudjacking for coastal NC soil?

Yes, polyjacking is generally superior for Wilmington's sandy coastal soils. The lightweight foam (2–4 lbs/cu ft) won't overload weak sub-base the way mudjacking's heavy slurry (100–150 lbs/cu ft) can.

Can polyjacking fix a cracked driveway or only a sunken one?

Polyjacking lifts and levels sunken slabs but does not repair structural cracks. If cracks are wider than 1/2 inch or the slab has multiple fracture planes, full replacement is the appropriate remedy.

How soon can I use my driveway after polyjacking?

You can drive on your driveway within 30 minutes of polyjacking completion. Most jobs are finished within 1–3 hours total. The concrete patching compound used to seal the injection holes may take a few more hours to fully cure, but vehicle traffic is safe immediately.

Will polyjacking work if my driveway keeps sinking due to drainage problems?

Polyjacking will lift the slab, but if drainage problems aren't fixed, settling will likely recur within 3–7 years. The repair is only as durable as the soil beneath it. Before or alongside polyjacking, address the root cause: water pooling near the driveway, poor grading, or eroded sub-base. When drainage is corrected, polyjacking delivers a long-term solution. When it's ignored, you're treating the symptom, not the disease.
