Polyurethane Foam Concrete Lifting: Cures in 15 Minutes

What is Polyjacking?

Polyjacking uses a two-part expanding polyurethane that reacts on contact with the underlying soil, lifting concrete in minutes. The cured foam is lightweight, water-resistant, and dimensionally stable, so it works where heavy mudjacking grout shouldn't go (interior slabs, pool decks, lightweight sub-bases).

How polyurethane foam lifts concrete

Have you ever tripped over a sunken concrete slab on your property? It is incredibly frustrating to watch your beautiful driveway or pool deck sink. We know exactly how stressful those uneven surfaces can feel, which is why the Polyurethane Foam Injection (Polyjacking) process is such a game-changer.

You might be surprised to learn that fixing it takes minutes, not days.

Our team at Concrete Leveling Detroit uses a high-performance, two-part polyurethane that completely changes the repair process. The advantages are clear right from the start:

• Small holes: We only need to drill 5/8-inch holes, which are about the size of a penny.
• Fast expansion: The two parts react on contact with the sub-soil to lift the slab rapidly.
• Lightning-fast cure: The material hardens to 90% strength in just 15 to 30 minutes.

We love how the cured foam is incredibly lightweight, hydrophobic, and chemically stable. This means it repels water and prevents future washouts. For Metro Detroit homeowners, that brings some amazing benefits:

• A pool deck lifted without draining the pool
• An interior slab lifted with no concern about adding load to a compromised sub-base
• A pool-edge slab that won’t wash out from chlorinated water

When polyjacking beats slab-jacking

Foam, often called polyjacking, and slab-jacking both lift concrete effectively. The best choice always depends on the specific conditions of your property. We diagnose the issue on-site to pick the absolute right method for your home.

The Weight and Strength Difference

A major difference between the two methods is the weight of the material. Traditional slurry mixes can weigh over 100 pounds per cubic foot. Our polyurethane foam weighs only 2 to 6 pounds per cubic foot.

This massive weight difference matters when you have weak soil. Adding heavy mud to a compromised sub-base can actually cause the concrete to sink again later. We prefer polyjacking for delicate areas because it provides 40 to 60 PSI of compressive strength.

That is enough power to easily support a 4,000-pound passenger vehicle without burdening the soil. The table below compares the two options side by side:

Choosing the right fix saves you money in the long run. We highly recommend reading more on this head-to-head matchup. Check out our mudjacking vs polyurethane foam guide and learn exactly how polyurethane foam works.

What it costs

Polyjacking pricing scales just like other leveling work. The total expense depends on a few key factors that vary by property. We want to be completely transparent about these numbers.

Several elements will influence your final quote:

• Total square footage: Larger areas cost more overall but often have a lower price per square foot.
• Depth of settling: Slabs that have sunk several inches require more material to lift.
• Property access: Hard-to-reach areas take a little more time and effort to repair.

National data for 2026 shows that polyurethane foam injection averages $8 to $25 per square foot. Smaller repair projects tend to cost more per square foot than larger driveways. We often see minimum job fees ranging from $300 to $700 to cover the trip and specialized equipment.

Most Metro Detroit residential jobs run anywhere from $800 to $5,000. That might sound like a big investment up front.

Our customers consistently find this is 50% to 80% cheaper than pouring brand new concrete.
