Polyurethane Concrete Lifting FAQs – Everything You Need to Know

Polyurethane concrete lifting is a highly cost-effective solution that provides an excellent alternative to replacing concrete. In most cases, concrete lifting can be completed for less than half the cost of pouring new concrete. However, the savings can be even greater since the costs associated with demolition, removal, and landscaping are eliminated during the lifting process.

Polyurethane concrete raising achieves the same results as traditional mudjacking, but with a lightweight material that requires smaller and fewer injection holes. This process, also known as slab-jacking, foam jacking, foam lifting, or poly lifting, is the latest and most innovative concrete repair method available. Its lightweight and versatile properties make it ideal for lifting and leveling concrete slabs and floors, including driveways, sidewalks, patios, basements, and more.

With polyurethane concrete lifting, you can avoid costly and time-consuming replacements and enjoy a smooth and level surface in no time. Its cost-effectiveness and efficiency make it a popular choice for both residential and commercial applications. So, if you’re looking for a reliable and affordable solution to your concrete repair needs, polyurethane concrete lifting is the way to go.

Yes! We offer a 10-year, non-transferable limited warranty. If your concrete slab settles within 1/2 an inch to 1 inch within this period, we will return and re-pump.

We use high-density polyurethane foam to lift and stabilize concrete. This advanced material is specifically designed for concrete lifting and offers superior performance compared to traditional mudjacking slurry.

Why Polyurethane Foam is the Best Material for Concrete Lifting:

• ✅ Lightweight – Weighs only 2-4 lbs per cubic foot, reducing stress on the soil.
• ✅ Expands and Fills Voids – The foam flows into gaps beneath the slab, providing even support.
• ✅ Fast Curing Time – Hardens within 15 minutes, allowing immediate use of the repaired surface.
• ✅ Water-Resistant – Unlike mudjacking material, polyurethane does not absorb water or erode over time.
• ✅ Long-Lasting – Maintains its shape and density for decades without shrinking or decomposing.

Traditional mudjacking slurry is made from sand, soil, water, and cement. However, it can be heavy (100+ lbs per cubic foot) and prone to shrinking and erosion over time.

By choosing polyurethane foam lifting, you get a stronger, more reliable, and longer-lasting solution for concrete repair.

On the day of your job, injection holes are strategically drilled into the concrete slab that requires lifting. Our equipment is contained in a trailer, and has a sufficient length of hose to accommodate the project’s location. Our equipment remains parked, while our crew pulls out enough hose to reach the concrete that is to be repaired.

Polyurethane foam engineered specifically for concrete lifting is then injected as a two-part liquid beneath the slab, infiltrating all air spaces to fill voids, and raising it to the correct level upon expansion.

The concrete lifting foam has an average reaction time of 12 seconds. Within those 12 seconds, the foam travels in about a 6-foot diameter beneath your concrete, throughout the voids and then expands in a slow and controlled fashion.

Our lifting technician will “bunny hop” from hole to hole in order to lift your concrete slab to avoid breaking it. With use of our specialty equipment, this is extremely rare.

No. Our equipment is contained in a small truck and enclosed trailer, which is typically parked on the street.

Our polyurethane lifting hose can reach up to 350 feet, reducing the need for heavy machinery on your property.

Yes! Crack-sealing is an add-on service. We offer various crack-sealing methods, including foam backer rods and UV-stable polyurethane joint caulking.

Note: Crack-sealing is not included in our standard concrete lifting service but can be added to your project upon request.

The number and size of holes needed for concrete lifting depend on the method used.

Polyurethane foam lifting (foam jacking):

✅ Smaller injection holes: Only 5/8 inch in diameter (about the size of a dime).

✅ Fewer holes required: Typically spaced 3 to 5 feet apart, depending on the area and the void beneath.

✅ Minimal visual impact: Small holes blend better with the surrounding concrete and are patched with fiber-reinforced cement.

Mudjacking (traditional method):

🚫 Larger injection holes: About 1 5/8 inches in diameter (almost three times the size of foam jacking holes).

🚫 More holes required: Typically spaced every 16 inches.

🚫 Visible patching: Larger holes make the repair more noticeable.

Because of its smaller holes and longer-lasting results, polyurethane foam lifting is the preferred method for residential and commercial concrete leveling.

Foamjacking, also known as polyjacking or polyurethane concrete lifting, is an advanced method for raising and stabilizing sunken concrete slabs. It involves injecting expanding polyurethane foam beneath the slab to lift it back to its original position.

How Does Foamjacking Work?

• Small injection holes (only 5/8″) are drilled into the concrete slab.
• High-density polyurethane foam is injected beneath the slab.
• The foam expands, fills voids, and lifts the concrete back into place.
• The foam hardens within 15 minutes, providing a strong and stable foundation.

Benefits of Foamjacking Over Mudjacking:

• Lightweight – Won’t add stress to the soil.
• Water-resistant – Won’t erode or wash away over time.
• Faster curing – Slabs can be used the same day.
• Long-lasting – The foam maintains its shape and density for decades.

Foamjacking is a cleaner, more effective, and longer-lasting alternative to traditional mudjacking. If you’re looking for a reliable solution to fix sunken concrete, polyurethane foam lifting is the best choice!

Foam jacking (polyjacking) is the modern alternative to mudjacking.

Advantages of polyurethane foam lifting:

• Smaller holes – 5/8″ vs. 1 5/8″ for mudjacking
• Lightweight – Won’t add stress to the soil
• Permanent solution – Foam won’t shrink or erode
• Quick curing – Ready to use in 15 minutes

Our polyurethane foam used for concrete lifting is extremely strong and durable, capable of supporting heavy loads without losing its integrity.

Weight Capacity of Polyurethane Foam:

• 100 PSI compressive strength at 1-inch thickness.
• 14,000 – 20,000 lbs per square foot in free-rise form.
• Over 25,000 lbs per square foot when under pressure.
• Additional foam layers increase weight capacity per square foot.

Compared to traditional mudjacking, polyurethane foam is lighter, stronger, and more stable. It doesn’t add unnecessary weight to unstable soil, reducing the risk of further settlement.

If you need to stabilize high-load areas such as driveways, garage floors, or commercial slabs, our high-density polyurethane foam is designed to handle extreme pressure while providing long-term stability.

Yes, polyurethane foam is strong enough to support heavy loads, including vehicles and industrial equipment.

Strength & Durability:

• 100 PSI compressive strength per inch
• Supports over 25,000 lbs per square foot
• Designed to handle heavy traffic and commercial use

Unlike mudjacking, polyurethane foam will not shrink or deteriorate over time, making it ideal for driveways, garage floors, and commercial applications.

Yes, polyurethane foam is an eco-friendly solution for concrete lifting.

Environmental Benefits:

• Reduces Waste: Eliminates the need for concrete replacement, reducing landfill waste.
• Non-Toxic & Inert: The cured foam is chemically stable and does not leach into the soil.
• Water-Resistant: Prevents erosion and soil washout, helping to maintain stable ground conditions.

By choosing polyurethane foam lifting, you’re making a sustainable choice while preserving existing concrete structures.

Yes, polyurethane foam provides a precise and controlled lift for even leveling.

How It Works:

• The foam expands slowly and evenly to prevent cracking or overcorrection.
• Our technicians use a multi-point injection process to ensure balanced lifting.
• Unlike mudjacking, foam expands to fill voids completely, preventing further settling.

Our advanced lifting techniques ensure that your concrete is raised evenly without damage.

No, polyurethane foam does not shrink or degrade over time.

Why Foam is a Permanent Solution:

• Unlike mudjacking slurry, foam remains rigid and stable once cured.
• It is water-resistant, meaning it won’t erode from moisture exposure.
• Proper drainage and ground stability ensure long-term performance.

With proper installation and site preparation, polyurethane foam will maintain its shape and effectiveness for decades.
