Concrete Leveling: Everything You Need to Know

Concrete is renowned for its robustness and is employed in creating various structures around our properties, including sidewalks, driveways, pool decks, and patios. Despite its strength, concrete is prone to damage and wear over time, necessitating appropriate repairs. 

Concrete leveling is a corrective technique for addressing issues related to uneven or sinking concrete surfaces. This guide aims to explore the concept of concrete leveling, its operational mechanisms, and the various methods employed in the process. 

Additionally, we will cover the scenarios necessitating concrete leveling, the professionals to contact for expert assistance, and the associated costs. Aimed at both homeowners and business owners, this guide intends to assist you in deciding whether concrete leveling is a suitable solution for your specific requirements. 

Introduction to Concrete Leveling 

What is Concrete Leveling? 

Concrete leveling is a method employed to rectify uneven or sunken concrete surfaces. It entails elevating and aligning the concrete to its initial position, thereby eliminating hazards resulting from irregularities. This procedure enhances the safety, functionality, and visual appeal of the concrete area. 

Concrete leveling goes by a few different names

  • “Concrete Repair” 
  • “Concrete Lifting” 
  • “Concrete Raising” 
  • “Slabjacking” 
  • “Slab Lifting” 
  • “Concrete Jacking” 
  • “Cement Jacking” 

Depending on the method and tools used to perform concrete leveling, it might also go by one of its more technically specific names

  • PolyRenewal™ (our method), commonly known as “Polylifting,” “Polyjacking,” or “Polyurethane Foam Leveling.” 
  • “Mudjacking” 
  • “Stone Grout Slurry Leveling” or “Cement Slurry Leveling” 
  • “Self-Leveling Concrete” 

We’ll talk more about all of these in the next section but suffice it to say they are all very different processes for achieving the same or similar outcomes. 

Understanding How Concrete Leveling Works 

Concrete leveling aims to elevate and even out sunken or uneven concrete surfaces, restoring them to their original state. This process enhances safety, usability, and visual appeal. Common methods include polyurethane foam, stone slurry grout, mudjacking, and self-leveling concrete, with the choice influenced by specific circumstances and desired outcomes. 

To assess the need for concrete leveling, evaluate the condition of your surfaces. Seek professional assistance if you observe significant unevenness, sinking, or potential hazards. Even if your surfaces seem fine, consulting with experts is prudent to determine if leveling is necessary. 

Costs vary depending on factors such as area size, damage severity, chosen repair method, and scope of work. Obtain estimates from reputable companies for accurate pricing. 

Compared to replacement, concrete leveling offers a cost-effective solution. Consider factors like pros and cons, your requirements, and seek advice from professionals to make an informed decision. 

There are a few different ways that you can get your concrete to be level. In order of best to worst, here’s the list: 

1. Polyurethane Foam Concrete Leveling 

Polyurethane foam injection offers a swift and efficient solution for professionals to raise and even out sunken concrete slabs. This process entails injecting lightweight polyurethane foam through small holes drilled into the affected concrete. As the foam expands beneath the slab, it fills voids between the soil and the concrete, facilitating precise lifting and leveling.  

While similar to mudjacking, polyurethane foam injection elevates the process to a more effective level. Unlike mudjacking, polyurethane foam requires minimal drilling, sets within 30 minutes, and fills gaps completely, ensuring a smoother finish and longer-lasting results. It provides better value and durability compared to alternative leveling methods. 

2. Mudjacking 

Mudjacking presents a relatively straightforward procedure: a mortar-based slurry mixture is pumped beneath the slab, comprised of water, soil, sand, and cement, resembling mud upon mixing—hence the term “mudjacking.” Once cured, this mixture forms a solid, stable structure that fills the gaps causing concrete deformation. 

Though often effective, mudjacking has limitations. It’s unsuitable for lifting both slabs and heavy partition walls due to potential uneven lifting. Attempting it as a DIY project is strongly discouraged. Without proper training and equipment, mudjacking can inflict serious structural damage to your home. No amount of online tutorials can adequately prepare you for this complex task. DIY attempts may complicate repairs, leading to increased costs and further damage. 

3. Cement or Stone Slurry Concrete Leveling 

Stone slurry grout concrete leveling combines elements of mudjacking and polyurethane foam injection. It entails blending crushed stones, notably limestone, with water and applying the mixture using equipment similar to that used for polyurethane injection. 

Similar to mudjacking, it requires large 1-inch holes, but offers better control over the material thickness beneath the uneven slabs. Additionally, the stone and water mixture adds substantial weight, compressing the soil. Unlike mudjacking, this slurry mix typically fills voids completely, providing an environmentally friendly and durable solution. However, it generally comes at a higher cost compared to mudjacking. 

4. Self-Leveling Concrete 

Self-leveling concrete is just as it sounds—something you can apply yourself. It consists of polymer-fortified cement, but advancements have made it easier to use than ever before. Thanks to its fast drying time, minimal water needs, and compatibility with various materials and finishes, DIYers can achieve sleek, even surfaces when patching or resurfacing interior floors. 

Although pricier than standard concrete, self-leveling products cater to small-scale repair jobs and home improvement projects where structural reinforcement isn’t necessary. Formerly considered a specialty material, innovations have made self-leveling concrete accessible to everyday homeowners seeking cost-effective ways to revitalize their concrete floors. 

However, DIY repairs using methods like self-leveling concrete can quickly become hazardous and costly endeavors. 

When to Level Your Concrete 

There are numerous indications that your concrete may require leveling. If your driveway has caused damage to your car (a surprisingly common occurrence), it’s imperative to address the issue promptly by exploring concrete lifting solutions and repairing the affected area. 

Repeatedly driving over sunken or uneven slabs in your garage or driveway can damage your car’s suspension and tires, increasing wear and tear and necessitating maintenance. 

Cracks or sunken areas in concrete are clear indicators that leveling may be necessary. You might observe cracks forming on the basement floor, notice uneven steps, or witness cracks in exterior brick, stone, or siding. It’s also common for chimneys to crack or pull away from the home. 

Apart from detracting from your property’s appearance, cracked and uneven concrete poses safety risks and potential liabilities. Anyone can easily trip over sunken slabs, particularly the elderly or those with mobility issues, which is especially hazardous around concrete pool decks. 

The optimal time to address concrete leveling is before it escalates into a major issue. It’s crucial to contact local concrete leveling professionals as soon as you detect or suspect any problems with the concrete on your property.

When Not to Level Your Concrete 

There are two scenarios where concrete leveling is not warranted: minimal or no damage and extensive damage. 

Occasionally, during the curing process, concrete may develop minor hairline cracks that remain stable over time. While these cracks persist, they typically do not alter in size, appearance, or depth and can be addressed with cosmetic solutions instead of concrete lifting. 

However, concrete often deteriorates significantly over time, leading to severe damage. Portions may break off, and edges can crumble, posing risks to safety and structural integrity. In such instances, a complete replacement may be the only viable solution. 

Who to Call When You Don’t Need Leveling 

Before your concrete reaches a state where concrete lifting is no longer viable, contact concrete repair specialists such as Dry Pro for a comprehensive assessment and guidance on the most suitable repair strategy. 

Even if concrete leveling isn’t the ideal solution, we can suggest alternative options such as repouring or resurfacing to address your needs effectively. 

The Cost of Concrete Leveling 

A significant query regarding concrete leveling often centers on the financial aspect and determining the project’s cost. This matter is multifaceted, making it challenging to obtain a straightforward answer through online searches. Numerous factors influence the total cost, such as: 

  • Extent of the damage 
  • Size of the are requiring repair 
  • Appropriate repair method 
  • Amount of product required 
  • Labor, materials, permits

Concrete Leveling vs. Replacement: A Cost Comparison 

Detecting concrete damage early and addressing it promptly is essential. Concrete leveling techniques, especially utilizing PolyRenewal™, offer a swift and cost-effective solution. 

In cases where concrete is severely damaged and appears irreparable, complete demolition and repouring of cement are often necessary. This process is time-consuming, requiring days for curing and rendering the concrete unusable during this period. Additionally, the weight of concrete causes the newly poured slab to eventually settle into the ground. 

Concrete replacement is also financially burdensome, with costs often exceeding $5,000. However, opting for less invasive and proactive procedures can reduce expenses to an average of around $1,000. 

Average Price to Raise a Driveway 

Due to ongoing vehicle traffic, driveways endure significant wear and tear, making damages especially conspicuous. The cost of leveling driveways and garage floors typically varies from $800 to $4,000. 

Average Price to Raise a Patio 

Patios endure foot traffic rather than the weight of vehicles, unlike driveways and garage floors. Nevertheless, the cost range is comparable, often spanning from $800 to over $3,000. Likewise, elevating a porch might exceed $5,000, particularly if piering becomes necessary. 

Average Price to Raise a Walkway 

Sidewalks and walkways play a crucial role in providing access to homes, enduring heavier foot traffic compared to patios and porches. The cost for these areas can vary, typically ranging from approximately $500 to over $2,000.
