Jun 16

Slabjacking is a safe and cost-effective concrete repair technique for lifting sunken or uneven slabs back up into an even, stable position. It is much less costly than replacing the entire slab and maintains the appearance of the existing surface.

The time required to complete a concrete leveling project depends on the size of the job. But on average, a slab can be lifted and restored in just a couple hours. This is far shorter than it would take to replace the entire slab, and you can start using your new-look concrete immediately.

The cost of concrete leveling can vary, but it’s generally less expensive than a replacement slab. The most common methods for lifting sunken concrete include mudjacking, foam leveling and stone slurry leveling. Mudjacking costs $3 to $6 per square foot, while foam leveling is around $5 per square foot.

Regardless of the method used, the most important thing to keep in mind is that the underlying issue must be addressed. Otherwise, your new, level concrete will sink again. In some cases, soil erosion or expansive clay can cause voids underneath the concrete that lead to sinking over time. Unlike slab replacement, concrete leveling addresses these problems at their source and provides a long-lasting solution.


If you want to level a concrete slab with a self-leveling compound, you will need to work quickly. You only have a limited time to apply the product before it starts to set up. Most products take about 20-30 minutes to set up.

Concrete Leveling Contractors Twinsburg can use a variety of methods to lift and level sunken concrete. They can use mudjacking, which involves pouring a mixture of cement and water under the concrete slab to jack it up. Another method is polyjacking, which uses polyurethane foam to lift the concrete.

Uneven concrete around your home is not just a nuisance, it can also be dangerous. Besides tripping hazards, uneven concrete can cause structural damage to your property. It is essential to hire a concrete leveling expert immediately to prevent further damage and avoid costly repairs down the road.

The universal goal of concrete leveling is to lift sunken or settled concrete slabs back up into an even position. There are many different ways to achieve this goal, but the most popular are foam leveling and mud jacking.

Mudjacking uses a heavy mixture of cement and mud, while polyleveling uses an expandable foam. Regardless of which method is used, the process involves drilling holes into the surface of the concrete. Then, the poly or foam is injected into these holes. The expansion forces the soil underneath the concrete into the voids, lifting the sunken or uneven concrete. The holes are then filled with non-shrinking grout. This is a much safer and cleaner option than breaking apart and pouring new concrete.


The appearance of the finished product is an important consideration. A sunken slab is unsightly and can make your home look dilapidated. It’s also a safety hazard for anyone walking on it. Concrete leveling cement can fix these problems and leave you with a beautiful, level floor.

After the leveling compound is applied, a grinder can be used to remove any high spots. Once the grinder is finished, it’s almost impossible to see where the original hole was placed. This method of concrete leveling is quicker and more affordable than replacing the entire slab. In fact, it only takes a few hours to complete the job.
