Myth #1: “Polyurethane foam isn’t strong enough for heavy concrete.”
The Truth: High-density polyurethane foam is incredibly strong and is used to lift highways, bridge approaches, industrial warehouse floors, and commercial slabs. If it’s strong enough for transportation infrastructure, it’s more than strong enough for your driveway, pool deck, or sidewalk.

Myth #2: “Foam only fills voids—it doesn’t actually lift the slab.”
The Truth: Polyurethane foam does both! It expands to fill empty areas under the concrete and then exerts controlled upward pressure to lift the slab evenly. The foam also stabilizes weak soil, preventing future sinking.

Myth #3: “Polyurethane foam breaks down over time.”
The Truth: The foam is extremely durable and does not absorb water, shrink, rot, wash out, or erode. Mudjacking materials can deteriorate or wash away, but closed-cell polyurethane foam is stable and long-lasting—often outlasting the concrete itself.

Myth #4: “Foam isn’t suitable for big lifting jobs.”
The Truth: Foam is used for both small and major projects, including garage slabs, commercial walkways, warehouse floors, and pool decks. It provides precise lifting for entire slabs, even those needing several inches of adjustment.

Myth #5: “Polyurethane foam isn’t environmentally friendly.”
The Truth: The materials used for foam concrete lifting are non-toxic once cured, lightweight, and long-lasting. They reduce the need for concrete replacement, keeping old slabs out of landfills and minimizing heavy machinery on your property.

Myth #6: “Foam won’t work in South Carolina’s soil.”
The Truth: Polyurethane foam performs extremely well in our region because it doesn’t rely on soil strength to stay in place. It’s waterproof, controls soil movement, and seals voids to stop erosion—ideal for coastal areas, sandy soil, clay, and high-moisture environments.

Myth #7: “The holes drilled for foam are big and visible.”
The Truth: Injection holes for foam are tiny—about the size of a dime (⅜"). They are patched after lifting and blend in with the surrounding concrete. Most customers can’t find them afterward.

Myth #8: “Replacing concrete is cheaper than leveling it.”
The Truth: Foam lifting is typically 50–75% less expensive than replacement. Replacement requires demolition, hauling, forms, pouring new concrete, curing time, and yard repair. Foam lifting takes 1–2 hours and the slab can often be used the same day.

When people think of foam, they picture couch cushions or packing peanuts—not high-tech material capable of lifting sunken concrete slabs. But polyurethane foam is quickly becoming the top concrete lifting solution in South Carolina, offering a fast, clean, and long-lasting way to restore uneven concrete.
​
At Concrete Corrections, we use advanced polyurethane foam concrete lifting techniques to level everything from driveways and sidewalks to pool decks and patios. Whether you live on the storm-prone coast, the clay-rich Midlands, or the ever-shifting soils of the Upstate, polyurethane foam is proving to be the most dependable method of concrete leveling in South Carolina.

Let’s dive into some fun, surprising, and genuinely impressive facts about polyurethane foam—and why it’s the best choice for your home or business.

1. Polyurethane Foam Expands in Seconds—Lifting Concrete Faster Than Any Other Method
One of the biggest advantages of polyurethane concrete leveling is how quickly it works. Once the foam is injected beneath the concrete slab, it expands immediately, filling voids and gently raising the concrete back into position.
Why South Carolina homeowners love it:

• No long cure times
• Walk or drive on your repaired slab within minutes
• Most concrete lifting projects take under an hour

If you want a fast, reliable alternative to concrete replacement or mudjacking, foam is easily the best choice.

2. It’s Lightweight—So It Won’t Sink Into Soft South Carolina Soil
Traditional mudjacking uses heavy cement slurry that can actually weigh down soils and cause more sinking over time. But polyurethane foam weighs only a few pounds per cubic foot, making it the ideal solution for:

• Coastal sandy soils
• Moist or loamy Lowcountry soil
• Expansive clay common in Columbia, Lexington, and surrounding areas
• Areas with erosion or poor compaction

This ultra-lightweight material ensures your concrete lifting repairs are long-lasting.

3. Polyurethane Foam Is Completely Waterproof—Perfect for Our Wet Climate
From saltwater spray and coastal flooding to heavy thunderstorms and high humidity, South Carolina sees constant moisture. While mudjacking materials absorb water and deteriorate, closed-cell polyurethane foam is waterproof.
That means it’s perfect for:

• Pool deck leveling
• Driveway concrete repair
• Sidewalks near irrigation
• Slabs impacted by groundwater
• Coastal or marsh-adjacent properties

If you need concrete repair in Charleston, Myrtle Beach, Hilton Head, or other coastal regions, this waterproof foam is the best long-term choice.

4. Foam Fills Every Void—Making It Stronger Than Mudjacking
Because polyurethane foam flows before it expands, it reaches areas traditional cement slurry cannot. This makes it ideal for filling:

• Voids created by erosion
• Washouts from heavy rain
• Gaps caused by poor soil compaction
• Spaces created by burrowing animals
• Voids under driveways, walkways, and patios

This complete coverage ensures your concrete slab stays stable for years to come—making it a superior option for slab lifting and leveling across South Carolina.

5. Modern Polyurethane Is Eco-Friendly
Today’s polyurethane foams are engineered with environmentally-friendly ingredients and are completely inert once cured. They won’t react with soil, pollute groundwater, or introduce toxins into your property.
You’ll also reduce waste by avoiding unnecessary concrete demolition. Choosing foam concrete repair is one of the most sustainable options available.

6. It Requires Just a Penny-Sized Hole—Leaving a Clean, Seamless Finish
For many homeowners, appearance matters. Unlike mudjacking, which requires drilling large holes, polyurethane concrete lifting uses tiny ⅝-inch injection holes—barely noticeable once patched.
This small detail makes a big difference in:

• Driveway leveling
• Decorative concrete areas
• Pool decks
• Patios and porches

This clean finish is one reason many customers prefer foam over older methods.

7. Polyurethane Foam Is Strong Enough to Lift Highways and Airport Runways
Wondering if this lightweight foam is durable enough for your home? Absolutely.
The same foam used for residential concrete leveling is used for:

• State DOT highway repairs
• Airport runway stabilization
• Industrial Warehouse slab lifting
• Railroad track stabilization

If it can support an airplane, it can handle your SUV and everyday foot traffic with ease.

8. Foam Doesn’t Just Lift Concrete—It Stabilizes Soil
Polyurethane foam compacts loose soil and fills weak areas beneath your concrete. This added structural support prevents:

• Future settling
• Concrete cracks
• Repeated sinking
• Trip hazards

This is especially important for areas of South Carolina with fast-changing moisture levels, such as Greenville, Columbia, Anderson, and Summerville, where shifting soil is common.

9. It Works in Any Season—Heat, Humidity, or Cold
South Carolina is known for hot, sticky summers and occasional winter freezes. Fortunately, polyurethane concrete leveling works in nearly all temperature conditions.
Foam remains stable during:

• Extreme heat
• High humidity
• Rainy seasons
• Occasional freezes

This means you can level your concrete almost year-round, unlike traditional methods that depend heavily on weather conditions.

10. Foam Concrete Leveling Is 50–70% More Affordable Than Replacement
Here’s one of the best “fun facts” of all: polyurethane concrete lifting can save you thousands.
Foam is far cheaper than removing and replacing concrete—and far less disruptive.
Benefits include:

• No demolition
• No waiting days for concrete to cure
• No mess or heavy equipment
• No tearing up your landscape

Whether you need driveway leveling in Murrells Inlet, sidewalk repair in Myrtle Beach, or pool deck concrete leveling in Charleston, polyurethane foam delivers fast results at a lower cost.
