Top 7 Benefits of Polyurethane Foam Concrete Raising

Should you raise your sunken concrete, and if so, how should you do it? If you’re looking into concrete raising services, you may find conflicting information regarding the best way to deal with it. The goal of this article is to help you understand the facts and benefits of polyurethane concrete raising compared to the limitations of old repair methods. If you’re tired of dealing with sunken or uneven concrete surfaces and want a quick, easy, and effective solution, you’ve come to the right place!

How Does Polyurethane Foam Concrete Lifting Work?

Polyurethane foam concrete lifting is a relatively non-invasive way to lift and level concrete surfaces that have sunk. This specialized material was first made for large infrastructure repairs, but it is now used for projects in both homes and businesses. The foam is injected under the concrete, where it expands in all directions, binding loose materials and compressing the ground below the slab. Once the voids are filled and the subbase is compacted, the foam lifts the slab back to its original position. The material hardens in 15–30 minutes, so your concrete can be used right away without any restrictions. It’s super strong and completely water-resistant, making it a durable, long-term repair.

Why Choose Polyurethane Foam Concrete Lifting?

There are many reasons why polyurethane foam concrete lifting is the best way to lift and level concrete surfaces that have sunk. Here are the top 7 benefits:

  1. Quick and Clean: Polyurethane foam concrete lifting materials fully cure quickly and without a mess. This means you can enjoy the benefits of a level concrete surface as soon as we’re done! 
  2. Durable and Long-Lasting: Polyurethane foam is an incredibly durable material that is water resistant and designed to last for decades. Once injected beneath your concrete surface, it will remain there without changing shape or size, providing long-lasting support and stability.
  3. Cost-Effective: Compared to old mudjacking methods or removal and replacement, polyurethane foam concrete raising is much more cost-effective. Our polyurethane will lift and level the surface in just a single application, and results in a long-lasting repair.
  4. Versatility: As a polyurethane specialist, we have many different polyurethane materials – each designed to deal with different specific problems. Some foams have extreme lifting power, while others are designed to only stabilize slabs without lifting them. We also have polyurethanes used for Deep Injection which displaces free water and works to strengthen large areas of subgrade material far below the concrete surface.
  5. Lightweight Material: Concrete wouldn’t sink so badly if it were not so heavy. Old concrete raising methods (mudjacking) added significant weight (100 lbs/cuft) to already compromised areas. Polyurethane is a very lightweight material (4 lbs/cuft) that doesn’t exacerbate an existing issue.
  6. Less Intrusive: Compared to mudjacking, polyurethane foam concrete lifting causes minimal disruption to your property, making it the most non-invasive solution available. Mudjacking defaces concrete surfaces by requiring many large (1-2 inch) holes being placed in the slabs.
  7. The choice of Engineers: More and more commercial properties, municipalities, and Departments of Transportation are requiring polyurethane materials for the raising and stabilization of concrete that’s sinking or subject to unstable subgrades. Engineers clearly understand the technical advantages of polyurethane over any type of mudjacking slurry – even those made with high concentrations of cement.


Polyurethane foam concrete lifting is a proven solution that provides a non-invasive, long-lasting repair to sunken, settled concrete. Polyurethane is an easy choice. Our process does not deface your concrete like old methods and results in a long-term solution. The next step is to select the best, most specialized contractor for your project!
