Benefits of Concrete Lifting via Polyurethane Foam Injection

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

  • It’s a permanent solution. Unlike mudjacking, which uses a heavy cement slurry, polyurethane foam is super lightweight and won’t add more weight to soil that’s already having trouble supporting a slab. This means your lifted slab won’t start to sink again.
  • It’s a cost-effective solution. Polyurethane foam injection is a cost-effective alternative to digging up the old slab and replacing it with a new one.
  • It’s a quick procedure. Using polyurethane foam injection to lift a concrete slab usually doesn’t take more than a few hours, tops.  After the repair is complete, you can start using the slab again.
  • Polyurethane foam is super lightweight. It won’t add extra weight to the soil. This is important because if the soil is already having trouble holding up the slab, adding more weight to it won’t solve the problem.
  • It’s an environmentally-friendly solution. Polyurethane foam won’t leach harmful chemicals into the soil. Therefore, it’s a green solution you can feel good about using.
  • 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. If the soil underneath the slab is saturated with water, this can cause erosion leading to voids which the slab with then sink into.

Weak soil that can’t hold up the slab. Some types of soil are weaker than others and will have trouble supporting a heavy concrete slab.

Expansive soil. Expansive soils are those that expand as they soak up water, and then shrink when they dry out. This causes movement in the soil which can – over time – lead to an unlevel slab.

Invasive tree roots. You’ve probably seen this many times in your life. Tree roots push up from under the slab and cause sections of it to become uneven.

What are the Different Ways to Lift a Concrete Slab?

Traditionally, uneven concrete slabs were fixed either via digging up the sunken slab and replacing it with a new one, or via ”mudjacking”. However, these weren’t the best solutions for a variety of reasons which we’ll explain below. Today, the majority of uneven concrete slabs are repaired using polyurethane foam injection.

The mudjacking procedure involves drilling small holes in the concrete slab, and then pumping a slurry made up of water, soil, and cement under it in order to lift it back up. The problem with mudjacking is the weight of the slurry. It contains cement, so it’s heavy. If you place it on top of soil that was already having trouble supporting a slab, it’s not going to solve the problem. In fact, it could even make it worse.

Concrete Replacement

When you replace a concrete slab you dig up the old one and then pour new concrete. This is a time-consuming fix. When you pour concrete there’s a certain amount of downtime required as you wait for the slab to dry and harden (cure). So, you won’t be able to use the slab right away. Also, if the soil wasn’t able to hold up the old slab, it’s not going to be able to hold up the new one either.

Of course, you should never add additional concrete to a slab thinking you’re going to ”even it out”. This will only add more weight to an already sinking slab.

Polyurethane Foam Injection

Polyurethane foam injection is also referred to as ‘’slabjacking’’. It’s a minimally-invasive procedure that, like mudjacking, involves drilling small holes in the concrete and then pumping in a material that lifts the slab. The difference is that polyurethane foam is extremely lightweight. Because of this it’s able to lift the slab back into position and keep it there. It’s also a quick repair. As soon as it’s done you can start using the slab again.
