Polyurethane Foam Lifting vs. Mudjacking: Which Concrete Repair Solution Is Better?

When it comes to repairing sunken or uneven concrete, two of the most popular methods are mudjacking and polyurethane foam lifting. But which one is right for your property? In this post, we’ll break down the differences between the two and explain why more homeowners and businesses are choosing poly foam lifting for long-lasting results.

What Is Mudjacking?

Mudjacking, sometimes called "slab jacking," is a traditional method where a thick slurry mixture (usually made of water, soil, sand, and cement) is pumped under the concrete slab to lift it back into place. It's been around for decades and works well for many types of repairs, but it does have some drawbacks.

Pros of Mudjacking:

• Cost-effective for very large areas

• Traditional method that's well understood

  
  

Cons of Mudjacking:

• The slurry material is heavy, which can cause the soil to sink again over time

• Large holes (about 1-2 inches wide) must be drilled into the concrete

• The material is not water-resistant, which can lead to future erosion

• Shorter lifespan compared to modern methods

• Material takes significantly longer to cure compared to polyurethane foam

  
  

What Is Polyurethane Foam Lifting?

Polyurethane foam lifting (also known as polyjacking or foam jacking) uses a special, lightweight foam that expands under the concrete. As it expands, it fills voids and gently lifts the slab with precise control.

Pros of Polyurethane Foam Lifting:

• Lightweight material — reduces risk of future sinking

• Small drill holes — typically the size of a dime (⅝ inch)

• Waterproof foam — resists future erosion and soil washout

• Quick cure time — you can use your concrete within minutes

• Long-lasting results — often decades without problems

• Better for the environment — many foams are made with eco-friendly materials

  
  

Cons of Polyurethane Foam Lifting:

• Slightly higher upfront cost compared to mudjacking

• Requires specialized equipment and experienced technicians

  
  

Which Method Is Right for You?

While mudjacking may be a cheaper option for some short-term fixes, polyurethane foam lifting offers a stronger, longer-lasting solution that protects your investment. It’s especially ideal for repairing driveways, sidewalks, patios, garage floors, and commercial slabs where durability matters most.
