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 lasting solution. An older method of lifting sunken concrete – mudjacking – uses a heavy cement slurry to raise the slab. The problem with this method is the fact that most slabs become uneven because the soil isn’t able to support the weight. If this is the case, adding a heavy cement slurry to the soil isn’t going to help. In fact, the slab could sink even deeper into the soil.
- It’s less expensive than replacing the slab. Lifting a slab via polyurethane foam injection is a cost-effective alternative to digging up and replacing the slab.
- Most jobs take only a few hours. Polyurethane foam injection usually only takes 2-3 hours, and then you can immediately begin using the slab again.
- Polyurethane foam weighs next to nothing. Polyurethane foam is able to lift a sunken slab without adding weight to the soil.
- It won’t leach harmful chemicals into the soil. This makes polyurethane foam injection an environmentally-friendly, 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…
Too much water under the slab. Drainage problems under the slab can lead to soil erosion and voids.
Weak soil that isn’t capable of supporting the slab. Some types of soil simply aren’t strong enough to support something heavy like a concrete slab.
Expansive soil. This is a type of soil that expands when it absorbs moisture, and shrinks when it dries out. Over time, this can cause a slab to become uneven.
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?
Prior to polyurethane foam injection, sunken slabs were fixed either by replacing them, or by repairing them using a technique known as mudjacking. Both have their drawbacks though, and that’s why, today, almost all slabs are lifted via polyurethane foam injection, also known as “slabjacking”.
Mudjacking
Mudjacking uses a cement slurry to lift the sunken slab. However, the slurry is heavy because it contains cement. If the slab sank because the soil wasn’t able to support it, mudjacking could make the problem worse.
Concrete Replacement
Replacing a slab means digging up the old one and pouring fresh concrete. This isn’t a quick fix because freshly-poured concrete needs time to dry and harden. Also, if the slab sank because of weak soil, the same thing will happen to the new slab. In other words, you haven’t solved the problem.
Something else. You should never pour new concrete on top of a slab in order to even it out. This will only add even more weight to an already sinking slab.
Polyurethane Foam Injection
Polyurethane foam injection (also known as ‘’slabjacking’’) is a fast, minimally-invasive technique for lifting a slab. Most jobs take no more than a few hours. The process involves drilling small holes in the concrete (they’ll be filled in later), and then injecting the foam under the slab. The foam immediately expands, and lifts the concrete. As soon as the repair is finished, you can begin using the slab again.
