What To Ask Before Scheduling Foam Lifting Concrete Leveling

Alison R. Sinclair | 01 Jan 2025

Concrete is one of the most durable building materials, but over time, sinking concrete slabs and cracked or uneven concrete surfaces become common issues due to soil erosion, moisture changes, and poor compaction. According to industry reports, over 50% of infrastructure repairs involve leveling jobs to restore concrete driveways, sidewalks, and foundations. Rather than opting for costly concrete replacement, many property owners choose polyurethane concrete lifting, an efficient and long-lasting alternative.

Before hiring local concrete leveling experts, it's important to understand the process and ask the right questions. Here’s what you should ask a concrete leveling company before scheduling a project to ensure you get the best results.

Key Takeaways

  • Understand if Foam Lifting Is Right for You – Polyurethane foam is ideal for stabilizing sunken slabs but may not be suitable for severely cracked or deteriorated concrete. A professional assessment ensures the best approach.
  • Know How the Process Works – Foam lifting involves injecting expanding polyurethane beneath the slab to lift and support it. The process is fast, minimally invasive, and typically allows for immediate use of the concrete.
  • Check for Long-Term Stability – While foam injection provides a durable fix, addressing underlying issues like poor drainage or soil erosion is key to preventing future settlement and ensuring lasting results.
  • Compare Concrete Leveling Methods – Foam lifting is superior to mudjacking and concrete replacement in many cases, offering a lightweight, cost-effective, and long-lasting solution with minimal downtime.
  • Understand the Costs and Warranty – Concrete lifting with foam costs significantly less than full slab replacement. Always ask about pricing, warranty coverage, and long-term maintenance recommendations before committing.
  • Choose a Reputable Contractor – Look for experienced concrete leveling professionals with strong reviews, proper certifications, and a track record of successful projects. Getting multiple estimates helps ensure quality service.

1. Is Foam Lifting the Right Concrete Leveling Method for My Project?

Not every concrete leveling method is suitable for all situations. Polylifting works exceptionally well for sunken concrete slabs caused by shifting soil or voids beneath the slab, but it may not be effective for concrete with severe structural damage.

A professional contractor will assess your concrete surface to determine if foam jacking is the best solution. If your concrete is severely cracked or breaking apart, a combination of concrete repair and foam leveling might be required. Ask about the root cause of concrete settlement to prevent future issues.

2. How Does the Foam Concrete Lifting Process Work?

The foam concrete lifting process involves injecting polyurethane foam beneath the slab to raise and stabilize it. The contractor drills into the concrete, injecting a special lightweight polyurethane foam that expands and fills voids under the slab. The foam creates a stable base, lifting the slab back into position while preventing future settling.

Compared to traditional slurry leveling methods, foam lifting is faster, cleaner, and more durable. The entire process typically takes just a few hours, and the concrete is ready for use within 15–30 minutes.

3. Will This Concrete Lifting and Leveling Method Fix My Uneven or Sunken Concrete?

In most cases, concrete lifting with polyurethane effectively levels uneven concrete and prevents further damage. However, it’s important to understand that foam leveling does not repair deep cracks or major structural failures.

If your concrete area has hairline cracks or minor surface imperfections, polyurethane foam injection can help stabilize it and prevent further deterioration. However, if the slab has significant breakage, additional concrete repair methods such as crack filling or sealing may be necessary.

4. How Long Will It Take to Lift and Level Concrete Using Foam?

One of the biggest advantages of polyurethane concrete raising is its quick curing time. Unlike new concrete, which requires days to fully cure, foam is injected and expands within minutes, allowing for immediate use of the surface.

Most concrete leveling projects are completed within a few hours, making it an ideal solution for commercial and residential applications. However, factors such as slab size, number of voids, and weather conditions can influence the total project duration.

5. Can Foam Injection Be Used for My Sunken Concrete Slab or Concrete Driveway?

Yes, foam injection is highly effective for a variety of applications, including concrete driveways, patios, sidewalks, garage floors, and even industrial spaces. The process is versatile and can be used on both small residential projects and large-scale municipal infrastructure repairs.

However, not all concrete problems can be solved with foam. If a sunken concrete slab is severely deteriorated or has deep structural cracks, additional concrete lifting solutions or concrete replacement may be needed.

6. Will This Leveling Method Prevent Future Sinking Concrete Slabs?

A major concern for property owners is whether concrete lifting and leveling services will provide a permanent solution. While polylift concrete leveling stabilizes settled concrete, ongoing soil movement can still cause future settlement if the underlying issues aren’t addressed.

To prevent future issues:

  • Ensure proper drainage around your concrete area to prevent water from weakening the soil.
  • Seal any cracked concrete to prevent moisture from penetrating and causing further damage.
  • Schedule periodic inspections with local concrete leveling professionals to check for early signs of settlement.

Proper maintenance can significantly extend the life of your concrete and reduce the need for future repairs.

7. How Does Polyurethane Concrete Lifting Compare to Other Leveling Methods?

There are several various concrete leveling methods available, but foam leveling is one of the most efficient options. Here’s how it compares:

  • Foam Leveling vs. Mudjacking – Mudjacking uses a heavier cement slurry, which can lead to additional sinking over time. Foam creates a stable and lightweight base, reducing future settlement risks.
  • Foam Leveling vs. Concrete Replacement – Concrete replacement is costly, time-consuming, and disruptive. Foam jacking is a faster, cost-effective solution that restores stability without removal.
  • Foam Leveling vs. Self-Leveling Concrete – Self-leveling concrete is used mainly for surface repairs, while foam lifting corrects the root cause of settlement.

For long-term durability and cost savings, raising concrete with polyurethane is often the best choice.

8. What Are the Costs of Concrete Lifting and Leveling Services?

The cost of concrete lifting and leveling today depends on several factors, including the size of the concrete area, the extent of settlement, and local labor rates. On average, poly level foam lifting costs 50%–70% less than concrete replacement, making it a more economical option.

To get an accurate estimate, it's best to contact your local concrete leveling professionals for a quote. Many companies offer free inspections to determine the best approach for your project.

9. Does This Concrete Leveling Service Come with a Warranty?

A reliable concrete leveling company should offer a warranty on their services, ensuring that the repair lasts for years. Ask about the warranty coverage and whether it includes future settlement or additional concrete repair needs.

Additionally, inquire about maintenance recommendations to help maintain your concrete and extend its lifespan.

10. How Can I Find the Best Concrete Leveling Companies Near Me?

Finding local concrete leveling experts is crucial to ensuring a successful project. Here are some key steps:

  1. Research concrete leveling companies – Look for experienced professionals with strong customer reviews.
  2. Compare leveling services – Ensure they offer foam leveling and other necessary repair solutions.
  3. Ask for references – Request previous project examples or customer testimonials.
  4. Get multiple estimates – Compare pricing and warranties before making a decision.

FAQs
Concrete sink issues are typically caused by soil erosion, poor compaction, or excess moisture beneath the slab. As the ground shifts or washes away, the concrete loses support, leading to settlement. Addressing drainage problems and using concrete lifting with foam can help prevent further sinking and restore stability to the surface.
Yes, foam lifting is effective for a wide range of sunken or uneven concrete surfaces, including driveways, sidewalks, patios, parking lots, and even large industrial floors. However, if the concrete is severely cracked or deteriorated, additional repairs may be necessary to ensure long-term durability and stability.
Once the foam expands and cures, it creates a strong, dense foundation capable of supporting significant weight. It can handle heavy vehicle traffic on driveways and parking lots, as well as industrial equipment on warehouse floors. The exact load-bearing capacity depends on the type and density of foam used during the process.
Yes, extreme temperatures can impact how foam expands and cures. Cold weather can slow down the expansion process, while excessive heat may accelerate it. Experienced contractors adjust the application method based on weather conditions to ensure proper leveling and long-term performance of the repaired concrete.
If your concrete sink issue is due to soil shifting or minor settling, foam lifting is usually the best option. However, if the slab has deep cracks, severe structural damage, or is crumbling, a full replacement might be necessary. A professional inspection can determine the best course of action for your specific situation.
Yes, one of the key benefits of concrete lifting with foam is its fast curing time. In most cases, the foam hardens within 15 to 30 minutes, allowing you to walk or drive on the surface almost immediately. This makes it an ideal repair method for high-traffic areas needing quick restoration.
No, foam lifting is minimally invasive and does not disrupt landscaping. Since the process requires only small drill holes in the concrete, there is no major excavation or soil displacement. Additionally, because the foam expands precisely under the slab, it does not spread into surrounding areas, keeping landscaping intact.
The depth of the foam injection depends on the extent of settlement and the size of the voids beneath the slab. Contractors determine the injection depth based on soil conditions and slab thickness. The foam expands to fill voids and create a stable foundation, ensuring the concrete remains level and supported.
Yes, polyurethane foam used for lifting is environmentally friendly. It is inert once cured, meaning it does not break down or release harmful chemicals into the soil. Additionally, foam lifting prevents the need for full concrete replacement, reducing construction waste and the environmental impact of new material production.
Yes, if improper drainage is causing a concrete sink problem, foam lifting can help redirect water away from the slab. By leveling the surface, water will flow as intended instead of pooling in low spots.
