Concrete Leveling: A Solution for Uneven Surfaces

Concrete is widely used in various construction projects due to its durability and strength. However, over time, concrete surfaces can become uneven, posing safety risks and affecting the aesthetics of a property. In this article, we will explore the concept of concrete leveling, its importance, methods used, benefits, factors affecting the cost, and provide answers to frequently asked questions.

What is Concrete Leveling?

Concrete leveling, also known as slab jacking, is a process that corrects uneven concrete surfaces. It involves raising sunken or uneven concrete slabs to their original position. This technique eliminates trip hazards, prevents further damage, and restores the functionality and appearance of the concrete.

Signs of Uneven Concrete Surfaces

Identifying signs of uneven concrete surfaces is crucial for determining the need for concrete leveling. Some common indicators include:

  • Unevenness or slopes in concrete walkways, driveways, or patios
  • Cracks in the concrete
  • Water pooling or drainage issues
  • Uneven gaps between concrete slabs
  • Doors or windows sticking

The Importance of Concrete Leveling

Concrete leveling offers several benefits for both residential and commercial properties. It helps to:

  • Improve safety by eliminating trip hazards
  • Prevent further damage to concrete structures
  • Enhance the aesthetics and curb appeal of a property
  • Restore functionality to sunken or uneven surfaces
  • Avoid costly repairs by addressing the issue promptly

Different Methods of Concrete Leveling

There are several methods used for concrete leveling, depending on the specific requirements of the project. These methods include:

  • Polyurethane Foam Injection: Foam is injected beneath the sunken concrete, expanding to lift the slab and fill voids.
  • Concrete Grinding: Uneven surfaces are smoothed by grinding down the higher areas of the concrete to create a level surface.
  • Pressure Grouting: This method involves injecting a cement slurry into the voids beneath the concrete to raise it.

The Process of Concrete Leveling

Concrete leveling typically follows a systematic process:

  1. Inspection: A professional assesses the condition of the concrete surface and determines the appropriate method for leveling.
  2. Preparation: Any debris or obstacles on the surface are cleared to ensure a smooth leveling process.
  3. Drilling: Small holes are strategically drilled into the concrete slabs for slab jacking or foam injection.
  4. Injection: foam is injected into the holes to raise the concrete.
  5. Finishing: Once the concrete is leveled, the holes are filled, and the surface is smoothed and restored.

Benefits of Concrete Leveling

Concrete leveling offers numerous benefits, including:

  • Improved safety by eliminating trip hazards
  • Enhanced durability and longevity of concrete surfaces
  • Restored functionality and usability of affected areas
  • Cost-effective compared to complete concrete replacement
  • Aesthetically pleasing appearance and increased property value

Factors Affecting the Cost of Concrete Leveling

Several factors influence the cost of concrete leveling projects. These include:

  • Size and complexity of the area
  • Level of damage and extent of leveling required
  • Accessibility to the affected area
  • Chosen leveling method
  • Local labor and material costs


Uneven concrete surfaces can be a significant issue, compromising safety and aesthetics. Concrete leveling offers an effective solution by raising sunken slabs and restoring them to their original position. It eliminates trip hazards, improves functionality, and enhances the overall appeal of residential and commercial properties. By addressing signs of unevenness promptly, property owners can avoid costly repairs and ensure the longevity of their concrete structures.


Concrete leveling is suitable for most types of concrete surfaces, including sidewalks, driveways, patios, and garage floors.

The duration of the process depends on the size and complexity of the project. Generally, it will take less than an hour.

Concrete leveling requires specialized equipment and expertise. It is recommended to hire professionals to ensure proper and safe leveling.

Professionally performed concrete leveling should result in a seamless appearance that blends with the surrounding concrete.

With proper maintenance and care, a leveled concrete surface can last for many years, providing a durable and stable foundation.
