Concerned about a settled slab?
Contact Knoxville Concrete Company to request a concrete evaluation. Share your property location and describe the problem; our team will discuss the next inspection or project conversation and explain your options clearly.
Concrete Leveling & Lifting
Concrete settlement does not always mean the concrete needs to be demolished. When an existing slab has adequate strength and remains in usable condition, concrete leveling or lifting may raise uneven areas toward a safer, more functional elevation. This approach can improve the surface without automatically requiring full replacement.
Leveling concrete may help when a slab has dropped because of soil movement, poor base preparation, drainage, erosion, or washed-out material beneath slab areas. The process can involve controlled injection through small access holes to place support material beneath the concrete and fill voids. Depending on the site, the contractor may discuss polyurethane foam, a cementitious material, or another suitable option. Polyurethane foam is one possible method, not a universal solution; polyurethane products differ, and the right foam depends on the slab, soil, load, access, and drainage.
Concrete leveling examples
- Sunken driveways and sidewalks
- Patios, walkways, and concrete slabs
- Repair-versus-replacement evaluation
Signs that warrant an evaluation include a height difference at a joint, water collecting beside the slab, a rocking section, or a grade change that affects walking or vehicle access. We review the amount of settlement, concrete condition, drainage, surrounding structures, and possible causes before recommending lifting, repair, or replacement. Surface cracks may be cosmetic, but wide cracks, broken edges, severe movement, and weak concrete can change the recommendation. Concrete leveling may need to be paired with drainage, grading, or soil-related work because leveling alone does not correct every cause of concrete settlement or sinking concrete.
Leveling is not a universal fix. The right result depends on the strength of the existing concrete, the soil beneath it, water conditions, access, the source of settlement, and the condition of the slab.
Need help choosing between leveling and replacement?
We can review the surface and explain whether your slab appears to be a candidate for concrete leveling, lifting, repair, or replacement.
How We Evaluate Uneven Concrete
A useful concrete leveling evaluation looks beyond the visible surface. We review the slab, nearby grades, drainage paths, soil conditions, access, and structures that could be affected by additional movement. Before the visit, note when the settlement began, whether water collects nearby, how the area is used, and whether anyone has attempted a previous repair.
- We discuss the history of the problem, including changes in the surface and whether the area carries vehicles, equipment, or foot traffic.
- We inspect settlement, cracks, edges, joints, and the concrete’s surface strength to help determine whether leveling or replacement is suitable.
- We look for water movement, erosion, holes, unstable soil, and other conditions that could create or enlarge voids beneath the concrete.
- We compare lifting, repair, and replacement based on site conditions, slab condition, drainage, access, and the likely scope of work.
- We explain the proposed process, material, access needs, possible holes and patching, cleanup plan, warranty terms, and expected work time.
Why the process matters
Pressure and injection work must be controlled. Too little support may leave voids beneath the slab, while excessive pressure can raise an area beyond the desired grade or affect nearby surfaces. Proper equipment and experienced crews address the full area instead of treating only one visible point.
Some property owners ask about mudjacking. This process typically introduces a cement-based grout through drilled holes to fill voids beneath concrete. Depending on the mix, limestone or a similar aggregate may be used; “limestone grout” should describe the actual approved material, not an assumption. Other projects may suit polyurethane foam. Polyurethane foam is injected through smaller access holes and expands according to its formulation, but foam density, lift control, soil, load, drainage, and slab condition all matter. Neither material is automatically best for every repair.
Do not select a method only because it has the lowest advertised cost. Compare preparation, material, controlled equipment, scope, warranty, hole patching, cleanup, and correction of contributing site conditions before choosing a repair.

Tell us what has changed, where the settlement appears, how the area is used, and whether prior work was attempted. We will discuss the project and explain the next step.
Complete Concrete Support in Knoxville
Knoxville Concrete Company is a specialized concrete service operated by Anchored Construction & Restoration. We help homeowners, businesses, and light industrial clients across Knoxville with concrete leveling, lifting, repair, and replacement through experienced in-house crews and a full-service approach.
Depending on the project scope, our work may include demolition, excavation, dirt work, grading, drainage preparation, forms, reinforcement, cleanup, waste removal, and surrounding site restoration. When water or erosion contributes to settlement, grading or drainage work may support a more appropriate concrete repair. When the existing concrete lacks sufficient strength, replacement may be a better option. These services do not mean every foundation or foundation repair problem can be resolved by the same team or method; site conditions, permits, engineering, and project requirements must be confirmed.

Request a Concrete Leveling Evaluation
If you are dealing with uneven concrete, you may be comparing leveling methods, wondering whether your slab can be saved, or deciding between repair and replacement. An evaluation helps clarify the condition of the concrete, the possible cause of settlement, the likely process, and the next practical step without committing you to any work.
If you are learning
- “See if leveling may fit your slab”
- Share the basic condition and location
- Use the short evaluation form
If you are comparing options
- “Discuss lifting or replacement”
- Ask about repair scope and access
- Call for project questions
If you are ready to talk
- “Request a project evaluation”
- Describe the affected concrete area
- Discuss availability and next steps
Concrete Leveling Questions and Next Steps
Can every settled slab be lifted?
No. A slab must have enough strength and structural integrity to support the work. Severe cracks, broken sections, unstable soil, drainage problems, or major concrete settlement may make replacement or another concrete repair more appropriate. An evaluation can help determine whether leveling is suitable for a driveway, patio, sidewalk, or commercial slab.
Is polyurethane foam always the best material?
No. Polyurethane foam can be useful in some conditions, while grout or another support material may suit a different site. Soil, voids, access, load, drainage, and the surface condition all matter. The available material and injection method should be selected after reviewing the concrete and the conditions beneath it.
How should I compare repair cost and replacement cost?
Compare the condition of the concrete, the source of settlement, expected service life, drainage work, preparation, access, cleanup, and the full project scope. Ask whether the area will require drilled holes, patching, or soil-related work. A low initial price may not address the cause or provide the most appropriate long-term solution.
Knoxville Concrete Company works with homeowners, commercial property owners, and light industrial clients throughout Knoxville and surrounding East Tennessee communities. We provide clear scopes and complete support from preparation through cleanup. During the first conversation, we can discuss how the area is used, whether drainage may contribute to the problem, and what next step may be appropriate. We do not guarantee a repair method before evaluating the property.
