Benefits Of Concrete Leveling And Concrete Lifting Via Polyurethane Foam Injection

The benefits of concrete leveling and concrete lifting via polyurethane foam injection – also known as ”slabjacking” – include:

  • It’s a repair you only need to do once. Unlike the heavy cement slurry used in mudjacking, polyurethane foam is extremely lightweight. If a slab is sinking because the soil under it can’t support the weight, adding even more weight to the soil via a cement slurry isn’t going to solve the problem. In fact, it could make the slab sink even faster and then you’d need to repeat the repair using another method.

  • It’s a cost-effective solution. Leveling and lifting a concrete sidewalk, driveway, pool deck, or other slab via polyurethane foam injection is less expensive than digging up the old slab and pouring a new one.

  • The repair usually only takes a few hours. Also, you can start using the slab again about 15 minutes after the repair is complete. There’s virtually no downtime associated with polyurethane foam injection.

  • Polyurethane foam is super lightweight. It’s able to lift and level a concrete slab without adding extra weight to the soil.

  • Polyurethane foam is a green solution. It won’t release harmful chemicals into the soil. Therefore, it’s an environmentally-friendly fix 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 unlevel for a variety of reasons including…

Drainage problems leading to too much water under the slab. If there’s too much water under the slab it will wash away the soil and leave behind voids.

Weak soil that can’t support the slab. Not all soils are alike. Some aren’t strong enough to support the weight of a concrete slab.

Expansive soils. These are soils that swell considerably as they absorb water and then shrink considerably as they dry out. Over time, this seasonal movement in the soil – expanding and shrinking – can cause a slab to sink and become unlevel.

Invasive tree roots. Who hasn’t seen examples of tree roots pushing against a slab.

What Are The Different Ways To Lift And Level A Concrete Slab?

There are three main methods for fixing a sunken concrete slab: mudjacking, replacing the slab, and polyurethane foam injection. Traditionally, the first two methods were used. However, they have some serious drawbacks as you shall see. Today, polyurethane foam injection is the best way to lift and level a concrete slab.

Mudjacking is a repair solution that involves injecting a cement slurry – made up of water, soil, and cement – under the slab in or
