TL;DR: Polyjacking (polyurethane foam injection) costs $800–$2,500 for most residential jobs in Leland NC, or $5–$25 per square foot. It's 3–5× cheaper than full concrete replacement, cures in 15 minutes, and works especially well in our sandy coastal soils where mudjacking slurry washes out. Here's what you need to know before calling a contractor.

What Is Polyjacking and How Does It Work in Leland NC?

Polyjacking is a concrete lifting method that uses injected polyurethane foam to raise sunken driveways, patios, sidewalks, pool decks, and garage floors back to level. The process is straightforward: a contractor drills small 5/8-inch holes into your concrete slab, injects expanding polyurethane foam beneath it, and the foam lifts the slab as it hardens. Once the concrete reaches the correct height, the holes are patched with cement. The entire job typically takes 1–3 hours for residential projects.

Here in Leland and throughout Brunswick County, polyjacking has become the go-to solution for settling concrete because of our unique soil conditions. (Usda.gov) (Usda.gov) Our sandy loam soils - especially in newer developments like Brunswick Forest and Mallory Creek - lose support quickly when wet. The high water table near the Cape Fear River basin accelerates erosion under slabs, and our 54+ inches of annual rainfall, combined with tropical storm runoff, washes voids beneath concrete faster than inland areas. Unlike mudjacking slurry, which dissolves and washes away in wet conditions, polyurethane foam is waterproof and chemically stable after curing. That's why it holds up so much better in our coastal environment. The foam reaches approximately 90% of its final strength in just 15–30 minutes, meaning you can drive on your driveway or walk on your patio the same afternoon. This speed is a major advantage over mudjacking, which requires 24–48 hours of cure time before use.

How Much Do Polyjacking Services Cost in Leland NC?

Most residential polyjacking jobs in Leland run between $800 and $2,500, with costs typically ranging from $5 to $25 per square foot depending on the depth of settlement, number of injection points, and site accessibility.

Here's how costs break down for common projects:

What affects your price:

• Foam volume needed: Deeper voids require more foam and more injection passes, raising the cost.
• Number of injection points: Larger slabs or uneven settlement patterns need more holes, increasing labor and material costs.
• Site access: If your driveway is blocked by vehicles or landscaping, setup takes longer.
• Soil conditions: Highly unstable or saturated soil may require additional stabilization work.

For comparison, full concrete slab replacement costs $6–$15 per square foot installed - meaning a 200-square-foot patio replacement would run $1,200–$3,000 just for the concrete, plus removal and disposal. Polyjacking saves you 50–70% compared to full slab replacement.

Polyjacking vs Mudjacking vs Replacement: Which Is Right for You?

If you're researching concrete lifting, you've probably heard the term "mudjacking" thrown around. Here's how the three main options stack up:

Why polyjacking wins in Leland: Mudjacking uses a heavy slurry (cement, sand, water) that adds roughly 100 pounds per square foot to your already unstable sandy soil. In our wet coastal environment, that extra weight accelerates re-settlement. Polyurethane foam, by contrast, weighs only about 2 pounds per cubic foot and is hydrophobic - it doesn't absorb moisture or wash out. For homeowners in Leland, Hampstead, and Southport, polyjacking simply lasts longer.

When replacement is the right answer: If your concrete is severely cracked (not just settled), crumbling, or structurally compromised, leveling alone won't fix it. Replacement is necessary when the slab itself has failed, not just sunk.

Where Can Polyjacking Be Used Around Your Leland Property?

Polyjacking works on any concrete flatwork that has settled but remains structurally sound. Here are the most common applications we see:

Driveways: This is the most frequent job. Two-inch or greater settling is typical in Leland's sandy soils, especially in homes built in the last 15–20 years. Polyjacking restores proper slope for drainage and eliminates trip hazards.

Patios and pool decks: Settlement creates water pooling and trip hazards - especially problematic around pools. Polyjacking levels the surface, restores drainage, and eliminates liability concerns for HOA-regulated communities like Brunswick Forest.

Sidewalks and walkways: Uneven concrete is a liability issue. HOAs and municipalities increasingly require repairs to prevent trips and falls. Polyjacking is faster and less disruptive than replacement.

Garage floors: Interior applications with minimal disruption. Polyjacking works well for garage slabs that have settled unevenly, creating drainage problems or trip hazards.

What polyjacking cannot fix: Severely cracked concrete, slabs with structural failure, or concrete that is actively crumbling. If your slab has large cracks radiating from a central point or chunks missing, it needs replacement, not lifting.

What Should You Expect on Polyjacking Job Day in Leland?

Understanding the process removes a lot of buyer hesitation. Here's what happens:

Before the crew arrives: You don't need to clear your driveway or patio far in advance. The crew will mark injection points with chalk or paint the morning of the job. Most jobs require minimal prep.

During the work: The contractor drills small 5/8-inch holes at strategic points across the settled slab. Foam is injected in controlled passes, and the slab is monitored with a laser level to ensure it reaches the correct height. The process is relatively quiet - no heavy machinery or vibration.

After injection: Holes are patched with cement that matches your existing concrete. The patch cures quickly and is typically invisible after a few weeks of weathering.

Same-day use: Your driveway or patio is usable within 30 minutes. You can park on it or walk on it immediately.

Red flags to avoid when vetting contractors:

• No written estimate provided before work begins
• Pressure to decide or sign the same day
• No proof of liability insurance
• Unwillingness to provide warranty details in writing
• Vague pricing ("we'll call you with a quote after we see it")

A reputable Leland contractor will provide a written quote, explain the warranty coverage, and show before-and-after photos from similar jobs.

Why Leland NC Soil Conditions Make Polyjacking a Smart Choice

Our location is both a blessing and a challenge for concrete. Leland sits in Brunswick County's sandy loam belt, with soils that have low bearing capacity and high permeability. When it rains - and we get plenty of rain here - water moves through the soil quickly, washing away the fine particles that support your concrete slab.

The Cape Fear River basin and our proximity to the Intracoastal Waterway mean a characteristically high water table. During wet seasons and after tropical storms, that water table rises even higher, saturating the soil beneath your concrete and accelerating void formation.

Mudjacking slurry, which is essentially wet cement and sand, cannot withstand this environment. The slurry absorbs water, loses cohesion, and washes out - sometimes within a year or two. Homeowners who choose mudjacking in Leland often find themselves calling for repairs again within 3–5 years.

Polyurethane foam, once cured, is chemically inert and completely waterproof. It doesn't absorb moisture, doesn't degrade in wet conditions, and doesn't wash away. For coastal North Carolina homeowners, this durability difference is worth the slightly higher upfront cost.

Frequently Asked Questions About Polyjacking in Leland NC

How much does polyjacking cost in Leland NC?

Direct Answer: Most residential polyjacking jobs cost $800–$2,500, or $5–$25 per square foot, depending on the size of the settled area and depth of settlement.

Smaller jobs like a single sidewalk section might run $600–$900, while a full driveway or large patio typically costs $1,200–$1,600. Get a written estimate from a local contractor before committing - most offer free quotes.

How long does polyjacking last in coastal NC soils?

Direct Answer: Polyjacking typically lasts 5–10+ years in Leland's sandy coastal soils, significantly longer than mudjacking (3–7 years) because the foam is waterproof and doesn't degrade in wet conditions.

Longevity depends on whether the root cause of settlement is addressed. If water continues to erode soil beneath your slab, any lifting method will eventually re-settle. Proper drainage around your foundation helps extend the life of the repair.

Is polyjacking better than mudjacking for sandy soil in Leland?

Direct Answer: Yes. Polyjacking is superior for Leland's sandy, wet soils because polyurethane foam is hydrophobic and doesn't wash out, while mudjacking slurry absorbs water and deteriorates quickly in our high water table environment.

Mudjacking is cheaper upfront ($3–$8/sq ft vs. $5–$25/sq ft), but in coastal Brunswick County, you'll likely need repairs again within a few years. Polyjacking's higher initial cost is offset by longer-term durability.

What size holes does polyjacking leave in my concrete?

Direct Answer: Polyjacking uses 5/8-inch holes, which are much smaller than mudjacking's 1–2 inch holes and are easily patched with cement.

After patching and a few weeks of weathering, the repair is typically invisible. This is especially important if your driveway or patio is visible from the street or regulated by an HOA.

Can polyjacking fix cracked concrete or only sunken concrete?

Direct Answer: Polyjacking only fixes settled concrete that is structurally intact. It cannot repair severely cracked, crumbling, or structurally failed slabs—those require replacement.

If your concrete has large cracks radiating from a central point, chunks missing, or is actively crumbling, talk to your contractor about replacement instead of lifting.

How soon can I use my driveway after polyjacking?

Direct Answer: Your driveway or patio is usable within 30 minutes of job completion. The foam cures to approximately 90% strength in 15–30 minutes, so you can park on it or walk on it the same afternoon.

This is a major advantage over mudjacking, which requires 24–48 hours of cure time before use.

Does polyjacking come with a warranty in North Carolina?

Direct Answer: Yes. Most reputable contractors offer 1–5 year warranties on polyjacking work. Some offer limited lifetime warranties, though these typically exclude damage from flooding or extreme soil movement.

Always get warranty details in writing before work begins. Ask whether the warranty covers re-settlement or only defects in the foam injection itself.

Do I need a building permit for polyjacking in Brunswick County?

Direct Answer: No. Repairs to existing concrete flatwork, including polyjacking, generally do not require a building permit in Brunswick County unless structural elements are involved.

If you're unsure, contact Brunswick County Building Inspections to confirm for your specific property.
