Understanding the Concrete Leveling Process: From Assessment to Completion

Concrete leveling is a process that aims to restore uneven or sunken concrete surfaces, such as driveways, sidewalks, or patios, to their original level and condition. This article provides an in-depth understanding of the process, from initial assessment to completion.

The Importance of Concrete Leveling

Uneven or sunken concrete surfaces not only detract from the aesthetic appeal of your property but also pose safety risks. They can create tripping hazards and cause water pooling, which can lead to further damage. It addresses these issues by restoring the surface to its proper level, ensuring both safety and functionality.

Assessing the Concrete Surface

The first step in the process is assessing the condition of the surface. A professional contractor like iFOAM will inspect the area to determine the extent of the damage and identify any underlying issues. This assessment helps in developing an appropriate plan for leveling the concrete.

During the assessment, the contractor will look for signs of settlement, such as cracks, uneven slabs, or gaps. They may also use specialized tools to measure the degree of settlement and assess the stability of the subbase beneath the concrete.

Based on their findings, the contractor will provide you with a detailed explanation of the problem and recommend the best course of action.

Preparing for the Concrete Leveling

Once the assessment is complete, the next step is preparing the area for the process. This involves clearing the surface of any debris, loose materials, or vegetation that may hinder the leveling process.

Additionally, the contractor may need to address any underlying issues, such as poor drainage or soil compaction, before proceeding with the leveling. These preparations ensure a solid foundation for the leveling process and help prevent future problems.

The Concrete Leveling Process

1. Drilling Access Holes

To lift and level the concrete, access holes are drilled strategically into the affected areas. These holes provide entry points for specialized equipment used in the leveling process.

2. Injecting Polyurethane Foam

Polyurethane foam, a high-density material, is injected through the access holes into the voids beneath the concrete. The foam expands, filling the gaps and lifting the concrete slab to its original position. This process is repeated for each affected area until the desired level is achieved.

3. Monitoring and Adjusting

During the injection process, the contractor continuously monitors the lifting progress to ensure accurate leveling. They adjust the amount of foam injected as needed to achieve precise results and maintain a uniform surface.

4. Repairing Access Holes and Finishing

Once the concrete is leveled, the access holes are repaired using a compatible filler material to restore the surface’s integrity. The repaired areas are smoothed and finished to blend seamlessly with the surrounding concrete.


Understanding the concrete leveling process is essential when considering repairs for uneven or sunken concrete surfaces. It involves a thorough assessment of the damage, careful preparation, and the use of specialized techniques to restore the concrete to its proper level. By addressing these issues, you can enhance the safety and functionality of your property while restoring its overall appearance. If you’re facing concrete settlement issues, consult with a professional contractor who can provide expert guidance and perform it efficiently and effectively.
