Benefits Of Concrete Leveling And Concrete Lifting Via Polyurethane Foam Injection

There are a number benefits of concrete leveling and concrete lifting – also known as slabjacking or polyurethane foam injection – including:

  • It’s permanent. Other methods of lifting and leveling concrete – mudjacking, for example – add even more weight to soil that’s already having trouble supporting a slab. Because polyurethane foam is lightweight, it doesn’t add more weight to the soil which means the slab won’t continue to sink. It will remain level.

  • It’s cost-effective. Concrete leveling and lifting via polyurethane foam injection costs less than replacing a concrete slab.

  • It’s quick. With polyurethane foam injection there’s no downtime where you can’t use the slab. As soon as the repair is complete, you’re good to go!

  • It’s lightweight. Polyurethane foam is super lightweight and doesn’t add extra weight to the soil.  Other methods of lifting concrete such as mudjacking do add extra weight to the soil. If the soil was already having trouble supporting the slab, adding more weight to it via mudjacking won’t help.

  • It won’t harm the environment. Polyurethane foam doesn’t release harmful chemicals into the soil. Therefore, you can feel comfortable knowing it’s a safe, green solution.

  • Level concrete just looks good Sunken, uneven concrete is an eyesore!

What Causes Concrete Slabs To Sink Or Become Uneven?

Concrete slabs sink and become uneven for a variety of reasons including…

Problems with drainage. When there’s too much water under a slab it can wash away the soil and leave behind voids that the sidewalk, driveway, or pool deck will sink into.

Weak soil that isn’t able to properly support a slab. Some types of soil simply aren’t strong enough to support the weight of a concrete slab.

Expansive soil. This is soil that expands when it soaks up water and then shrinks when it dries out. Over time, this movement in the soil can lead to uneven slabs.

Invasive tree roots. This works exactly as you probably imagine. The tree’s roots push against the slab and cause sections of it to become uneven.

What Are The Different Ways To Lift And Level A Concrete Slab?

There were two traditional methods of lifting and leveling a concrete slab, mudjacking, and digging up the old slab and replacing it with a new one. Each method has its own drawbacks though, and as you’ll see, polyurethane foam is the best solution for lifting and leveling a concrete slab.

Before concrete slab lifting


Mudjacking is a procedure that injects a cement slurry under a slab in order to raise it up to where it was before. Yes, it works, at least temporarily. The problem with mudjacking is the fact that cement slurry is heavy.  If you put it on top of soil that was already having trouble suppo
