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 long term solution. Polyurethane foam is extremely lightweight. An older method of concrete lifting called “mudjacking” uses a heavy cement slurry to lift the concrete. If the slab sunk because the soil wasn’t able to support it – which is very common – mudjacking could make it sink even deeper into the soil. This won’t happen with polyurethane injection.
- It’s budget-friendly. Polyurethane foam injection is easier on the pocketbook that replacing the concrete.
- Most jobs can be completed in just a few hours. Polyurethane foam injection can usually be completed in 2-3 hours. Immediately after the repair is complete, you can begin using the slab again.
- It’s lightweight. Polyurethane foam lifts concrete without adding extra weight to the soil.
- It’s a green solution. Polyurethane foam won’t release harmful chemicals into the soil. Therefore, it’s an environmentally-friendly solution you can feel comfortable 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…
There’s too much water under the slab. Drainage problems can wash away the soil and eventually leave behind voids.
Weak soil. Sometimes the soil simply isn’t able to support something heavy like a concrete slab.
Expansive soil. Expansive soils are those that expand when they take on water and shrink when they dry out. Over time this seasonal 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 a Concrete Slab?
Sunken concrete slabs used to be fixed either by digging up and replacing them, or via a procedure referred to as “mudjacking”. Both have their drawbacks though, as you shall see. That’s why today, most lifting jobs are done via polyurethane foam injection.
Mudjacking
Mudjacking involves drilling small holes in the concrete and then injecting a cement slurry under the slab in order to lift it back up. The problem is the weight of the slurry. Since it contains cement, it’s not exactly lightweight, and this could cause the slab to sink even deeper into the soil.
Concrete Replacement
When you replace a concrete slab, you rip up the old one, and pour new concrete. This isn’t a quick fix though. Newly-poured concrete takes some time to dry and cure (harden). Also, if the soil wasn’t able to hold up the old slab, it won’t be able to hold up the new one either.
Whatever you do, don’t even think about pouring new concrete on top of a sunken slab in order to even it out. You’ll only be adding more weight to the soil, and this could cause the slab to sink even deeper.
Polyurethane Foam Injection
Polyurethane foam injection (also known as ‘’slabjacking’’) is a fast, minimally-invasive concrete lifting procedure that uses a lightweight and rapidly-expanding foam to lift the slab. It involves drilling a few holes in the concrete, and then injecting the special foam under the slab. The foam immediately starts expanding and this is what lifts the slab. Most jobs can be completed in just a few hours, and then you can immediately start using the slab again.
