Why Polyurethane is Better than Mudjacking

Mudjacking and polyurethane are two common concrete leveling solutions for homeowners and commercial properties looking for an alternative to costly replacement. Is one concrete leveling method better than the other? Let’s compare mudjacking vs. polyurethane.


What is Mudjacking?

Mudjacking is a concrete leveling method that pumps mud under a building, driveway or other sunken concrete to lift it. A specialized hydraulic pump pushes the mud mix into holes drilled in the slabs.

Concrete leveling with mudjacking doesn 19t produce long term results.

Mr. Level considers mudjacking the Flintstones approach to concrete leveling. With mudjacking, your sunken concrete is drilled with dime-size holes, pumped with mud and then the mud hardens up. To support the lifted concrete, mudjacking relies on underlying soils, which are impacted by the same elements that lead to cracking and sinking, so contractors are not able to guarantee the work.

What is Polyurethane?

An alternative concrete leveling option, polyurethane foam is used in place of mud. The foam expands after filling the holes drilled in the concrete slab. As the polyurethane expands, the concrete is lifted.

Concrete leveling with polyurethane is faster and less damaging than mudjacking.

Mr. Level uses polyurethane foam to raise concrete, fill voids and stabilize soil. By drilling a 5/8” hole (about the size of a thumbnail) into the concrete slab, we’re able to install a tapered delivery port into the same hole. The injection gun is connected to the port, delivering the polyurethane through the port and slab. Within seconds, the polyurethane expands, compressing loose soils and raising concrete. Polyurethane causes a chemical reaction with underlying soils that stabilizes the soil and concrete, so it doesn’t fracture or fail. This method proves longer lasting, which is why Mr. Level is able to offer a lifetime guarantee on our services.

Unlike mudjacking, concrete leveling with polyurethane is guaranteed to last a lifetime.

With polyurethane, fewer and smaller holes (an inch smaller, to be exact) are drilled into the slabs compared to mudjacking, so the finished product looks cleaner. Additionally, fewer resources and heavy equipment are required, so the job site is neater and the surrounding landscape isn’t damaged.



Mudjacking relies on underlying soils to support the lifted concrete. Heaving from a dramatic freeze and thaw cycle or settling from decaying tree roots or water damage can cause the underlying soils to shift and crack your concrete. There’s no guarantee your concrete will remain smooth and level with mudjacking.

With polyurethane, however, the chemical reaction with the soil causes the foam to harden, so it doesn’t fail. This stabilizes the soil and concrete, so your concrete should last a lifetime.


Environmental Friendliness

Polyurethane is made from non-toxic recycled material. It’s biodegradable when exposed to sunlight (i.e. in a landfill years down the road). Additionally, the pumping process allows for more control, compared to mudjacking, to protect the surrounding areas.

Mudjacking poses a few environmental concerns. With mudjacking, there’s little control, so its highly inaccurate and can fill sewer lines. Additionally, mudjacking uses a product that isn’t biodegradable.



The cost of mudjacking runs cheap compared to polyurethane. However, because there is no warranty or guarantee your concrete will remain leveled, you’ll likely need to pay to repeat the process.

It’s better to do it right the first time with polyurethane. While it does cost more upfront, the long-term costs and potential cleanup and repair costs prove significantly less. Additionally, polyurethane foam cures in minutes, so it’s ready to be walked on right away.


Concrete Leveling with Mr. Level

Uneven concrete is not only unattractive but can also be harmful to pedestrians and your vehicles. Not to mention, neglected, uneven concrete will only worsen over time, meaning more money to repair and more structural and safety issues to address. Don’t delay!
