Benefits of Concrete Lifting via Polyurethane Foam Injection
- It’s a cost-effective solution. Compared to tearing up the sunken slab and replacing it with a new one, polyurethane foam injection is easy on the pocketbook.
- It can usually be done in just a few hours. Polyurethane foam injection is a fast repair method, and you can begin using the slab immediately after the repair is complete.
- It weighs next to nothing. Because of this, polyurethane foam won’t burden the soil under the slab with additional weight. This is important because most slabs sink because the soil isn’t able to support them.
- It’s environmentally-friendly. Because polyurethane foam doesn’t release harmful chemicals into the soil, it’s a green 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…
Excess water under the slab. This can cause erosion that can lead to voids and, eventually, an unlevel slab.
Soil that isn’t strong enough to support the slab. Certain types of soil aren’t able to hold up something heavy like a concrete slab.
Expansive soil. This is soil that swells as it soaks up water, and shrinks as it dries out. Over time, this swelling/shrinking cycle can cause the slab to become uneven.
Invasive tree roots. This is when tree roots push against the slab and cause sections of it to become uneven.
What are the Different Ways to Lift a Concrete Slab?
It wasn’t so long ago that uneven concrete slabs were fixed either by replacing the slab or via a ” mudjacking ” repair technique. However, these solutions both had drawbacks and that’s why, today, almost all uneven slabs are repaired using polyurethane foam injection.
During the mudjacking procedure, a slurry consisting of soil, water, and cement is injected under the slab in order to lift it. The problem with mudjacking is the weight of the slurry. It contains cement so it’s not exactly lightweight. If the slab sank because the soil wasn’t able to support it, mudjacking isn’t going to solve the problem.
Fixing an uneven concrete slab via replacement means simply digging up the old slab and pouring a new one. This was once a popular way to solve the problem. However, it’s an expensive and time-consuming way to go about it. Newly poured concrete takes time to dry and harden. Also, if the slab sank because the soil under it was weak, the same thing will happen with the new slab. You haven’t solved anything.
Whatever you do, don’t pour fresh concrete on top of an unlevel slab thinking that you’re going to level it out. This will only add more weight to soil that’s probably already struggling to support the slab.
Polyurethane Foam Injection
Polyurethane foam injection (also known as ‘’slabjacking’’) is a minimally-invasive method of lifting sunken concrete. It can usually be completed in just a few hours, and then you can begin using the slab again. The procedure involves drilling small holes in the concrete (they’ll be filled in later), and then using them to inject the polyurethane foam under the slab. The foam expands immediately and this is what lifts the slab.
