Benefits Of Concrete Leveling And Concrete Lifting Via Polyurethane Foam Injection

The benefits of concrete leveling and concrete lifting – also known as slabjacking or polyurethane foam injection – are many, including:

  • It’s a solution that lasts. Polyurethane foam is lightweight so it won’t add more weight to the soil. Other methods of lifting and leveling concrete – for example, mudjacking – might lift the concrete temporarily. However, the cement slurry used to lift the slab is heavy and as such it adds even more weight to the soil. If the soil was having trouble supporting the concrete before, adding more weight to it isn’t going to help.

  • It’s a cost-effective solution. Concrete leveling and lifting via polyurethane foam injection is less expensive that replacing the concrete.

  • It’s quickly implemented. Polyurethane foam injection is not only a quick procedure, but it enables you to use the slab immediately after the repair is complete.

  • It’s lightweight. Polyurethane foam lifts and levels concrete without adding extra weight to the soil. A technique that adds extra weight to the soil –  mudjacking, for example – will not stop the sinking if the soil isn’t able to support a slab.

  • It doesn’t harm the environment. Polyurethane foam doesn’t release harmful chemicals into the soil. This makes it a 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…

Drainage problems. Too much water can wash away the soil under a slab leaving behind voids that the slab will then sink into.

Weak soil that can’t hold up the slab. Not all types of soil are strong enough to support the weight of a concrete slab.

Expansive soil. Expansive soil swells when it soaks up water and shrinks when it dries out. Over time this swelling-shrinking cycle can cause uneven slabs.

Invasive tree roots. You can probably guess how this happens. The 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?

Traditionally, uneven concrete slabs were repaired in one of two ways. They were repaired either via a technique called “mudjacking”, or by tearing up the uneven slab and pouring new concrete.  Both these methods have their drawbacks though. We’ll explain how each one of them works, and then we’ll explain how polyurethane foam injection works. You’ll agree with us that it’s the best way to lift and level a concrete slab.
