Understanding Sinking Concrete and the Benefits of Concrete Leveling

Do you notice worsening cracks or sinking concrete in your driveway, sidewalk, garage floor, or other surfaces? This common problem affects both homeowners and business owners. Left unaddressed, sinking concrete can create safety hazards, cause drainage problems, and decrease your property’s value.

Concrete leveling is a proven solution to restore uneven surfaces, prevent further damage, and protect your investment. At Airlift Concrete Experts, we specialize in lifting and leveling sinking concrete efficiently and effectively across Arkansas.

What is Concrete Leveling?

Concrete leveling is the process of raising uneven or sunken slabs back to their original position. This is done by injecting a stabilizing material beneath the slab to fill voids and provide support, restoring a level, safe surface.

At Airlift Concrete Experts, we specialize in polyurethane foam injection—a modern alternative to traditional mudjacking. Polyurethane foam is lightweight, water-resistant, and fast-curing, making it ideal for both residential and commercial applications. Once injected, the foam expands to lift the slab and provide long-term support that won’t wash out or deteriorate over time.

Common Causes of Sinking Concrete

Concrete is heavy, and its stability depends entirely on the soil beneath it. When the foundation shifts, erodes, or weakens, slabs can sink unevenly, leading to cracks, trip hazards, and structural concerns. Common causes include:

  • Poor soil compaction: Weak foundation from improperly prepared soil.
  • Erosion: Water runoff, plumbing leaks, or poor drainage washing away supporting soil.
  • Soil shrink-swell cycles: Expansive soils contract and expand with moisture changes.
  • Decaying organic material: Tree roots or other organic matter decomposing beneath the slab.
  • Uneven settling: Some areas sink more than others, creating slopes or tilted surfaces.

Prompt professional intervention is key to restoring settling concrete and preventing more costly repairs.

Answer your common concrete leveling questions so you can decide if concrete leveling is right for your settling concrete.

Are Concrete Leveling and Lifting the Same Thing? Mudjacking, Polyjacking and Slab Jacking Explained

The process of restoring sinking concrete is often called concrete leveling, but it goes by many other names depending on the method used. Common terms include:

  • Concrete lifting
  • Slab jacking
  • Polyjacking
  • Polyurethane concrete lifting or leveling
  • Foam lifting or leveling
  • Mudjacking
  • Pressure grouting

Some terms, like concrete lifting and slab jacking, are generic and describe the overall goal: raising and stabilizing sunken or uneven concrete. The other terms indicate the specific method or material used:

  • Polyurethane foam (Poly, Foam, Polyjacking) – a lightweight, water-resistant foam that expands under the slab, filling voids and lifting concrete efficiently.
  • Mudjacking – a traditional method that uses a mixture of sand, cement, and water injected beneath the slab to lift it.
  • Pressure grouting – uses cement-based or other grout materials to stabilize and level concrete.

At Airlift Concrete Experts, we specialize in polyurethane foam lifting for sinking concrete. Using high-quality foam manufactured by ECP (Earth Contact Products), this method combines precision, durability, and fast curing to provide a long-lasting solution for homes, businesses, and industrial properties across Arkansas.

What is better, Mudjacking or Polyjacking? 

One of the most common concrete leveling questions is: “Which is better, mudjacking or polyjacking?” Mudjacking refers to using a combination of topsoil and concrete that is injected under the sunken concrete slab to lift it. Polyurethane concrete leveling is the process of utilizing polyurethane foam and injectingMany property owners ask whether mudjacking or polyjacking is the best choice. Polyurethane foam leveling offers several advantages:

  • Fast curing: Ready for use in as little as 15 minutes.
  • Durable and water-resistant: Won’t wash away, absorb water, or degrade.
  • Fills gaps and voids: Expands to reach areas mudjacking cannot.
  • Less invasive: Fewer holes and faster cleanup.
  • Efficient: Minimal downtime for residential or commercial use.
  • Long-lasting: Stronger and more permanent than traditional mudjacking.

For most applications, polyurethane foam leveling is the most effective solution for sinking concrete.

How Long Does Concrete Leveling Last?

When performed with high-quality polyurethane foam, concrete leveling is a long-term solution. The foam is impermeable to moisture, does not break down, and maintains its strength for decades. Because the foam is protected beneath the slab, sunlight and weather exposure are not a concern.

Concrete leveling is also far more cost-effective than full replacement—offering permanent results for a fraction of the cost.

Where Can Sinking Concrete Lifted or Leveled?

Concrete leveling isn’t just for driveways and sidewalks—it’s a versatile solution that can be used anywhere concrete has begun to sink or settle. At Airlift Concrete Experts, we’re equipped to handle projects of all sizes, from small residential repairs to large-scale commercial and industrial leveling.

Whether it’s a trip hazard on your sidewalk or voids forming beneath a warehouse floor, our polyurethane foam technology delivers fast, precise, and long-lasting results. We’ve used this method to lift everything from garage floors and patios to grain bin foundations and even dam structures—no project is too large or complex.

Here are just a few examples of surfaces we commonly restore:

No matter the scope, our expert team can handle everything from small home repairs to major industrial lifting projects.
