The Ultimate Guide to Concrete Lifting

unlevel sidewalk

Concrete is a strong material used for many structures, like sidewalks, driveways, and patios. However, concrete can become uneven for a number of reasons including age or weather.

Concrete lifting is the best solution for fixing uneven and sinking concrete. This guide explains what concrete leveling is, how it works, and the different ways it can be done. This guide is for homeowners and business owners looking to find out if concrete leveling is the right fix for their needs.  

What is Concrete Leveling? 

Concrete leveling is a repair method used to fix uneven or sinking concrete. It raises and stabilizes the concrete back to its original position, reducing the risks associated with uneven surfaces. This process improves safety, usability, and also enhances the look of the concrete area.  

Alternative names for concrete leveling include: 

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

Depending on the methods and tools used for concrete leveling it may also be referred to by more technical names: 

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

Each of these concrete lifting methods is meant to achieve the same outcome: sturdy, level concrete. However, some are more effective than others, which we’ll explore in the next section.

The Four Leading Techniques of Concrete Leveling  

Concrete leveling lifts and evens out uneven or sunk concrete surfaces back to their initial placement. This enhances safety, usefulness, and appearance. 

Four popular methods are used: polyurethane foam, stone slurry grout, mudjacking, and self-leveling concrete. The best method to repair your concrete depends on the specific situation on your property.  

Generally, polyurethane foam is the best. Here is how they rank, from most effective to least: 

1. Polyurethane Foam Concrete Leveling  

This technique uses lightweight polyurethane foam, injected through small holes, to accurately lift and level slabs. It’s recognized for its efficiency, minimal disturbance, and durable outcomes, making it superior to alternative approaches.

2. Mudjacking 

Mudjacking is the process of injecting a mortar-based mixture under the slab. The thought is that the mud, clay, slurry, and other materials in the mudjacking solution will lift uneven concrete. Although it works well for s short time, mudjacking will eventually fail when exposed to rain or snow. Its components can easily be eroded by water.

3. Cement or Stone Slurry Concrete Leveling 

This approach merges features of mudjacking and polyurethane foam injection, utilizing a blend of crushed stones and water to provide a stable and long-lasting solution, though it comes at a higher expense compared to mudjacking. 

4. Self-Leveling Concrete 

Tailored for DIY enthusiasts, self-leveling concrete caters to minor repairs and home enhancement projects, offering an accessible way to attain near even surfaces. Yet, lacking professional knowledge can result in difficulties and extra costs. 

When to Level Your Concrete   

When whether you need concrete lifting or not, it’s essential to spot key indicators that demand prompt action to preserve your property’s safety and appearance: 

  • Visible Cracks and Uneven Surfaces: Noticeable cracks or irregularities on your driveways, sidewalks, or patios signal the need for leveling. These defects not only pose tripping hazards but can also cause extensive damage if ignored. 
  • Water Accumulation: If water pools on your concrete after rain, this suggests unevenness that could lead to water damage and potentially affect the foundation. 
  • Vehicle Damage: Experiencing damage to your vehicle’s suspension or tires from driving on your driveway indicates that leveling is required. 
  • Landscape Changes: Alterations in the surrounding landscape causing uneven concrete surfaces call for leveling to avert accidents and enhance usability. 
  • Safety and Liability Issues: On pool decks or busy pathways, uneven concrete greatly heightens the risk of trips and falls, requiring immediate attention to mitigate homeowner liability. 

Promptly addressing these concerns can prevent expensive future repairs and keep your property both safe and attractive.

Situations Where Concrete Leveling Isn’t the Solution 

Not every concrete problem calls for leveling. Small, surface-level cracks may need only minor cosmetic repairs, while severely damaged, crumbling concrete could require full replacement. 

Groundworks provides professional evaluations to identify the best repair approach, offering alternatives when leveling is not the optimal solution. 

Understanding Concrete Leveling Costs 

Calculating the cost of concrete leveling projects can vary widely, largely because several factors influence the final price, making it challenging to provide an accurate quote without a thorough inspection. 

Key factors that determine cost include: 

  • Severity of the concrete damage 
  • Size of the area needing repair 
  • Selected repair method 
  • Quantity of materials needed 
  • Costs for labor, materials, and any necessary permits 

To get an accurate cost for your concrete leveling job, the best step is to engage with local specialists who can perform a complimentary inspection and provide a quote without any commitment. This approach guarantees that the estimate is tailored to the specific requirements of your project.

Concrete Leveling Versus Replacement 

When facing concrete issues, you have two main choices: leveling the existing concrete or completely replacing it. Financially speaking, catching problems early and opting for leveling, especially using PolyRenewal™, tends to be more affordable. This method is quicker and less expensive. 

However, severely damaged concrete may appear to need replacement, which is a longer and costlier process. Additionally, replacement doesn’t solve the original problem, possibly leading to future issues with the new concrete. 

Concrete replacement costs can surpass $5,000, whereas early intervention with leveling can average closer to $1,000. Cost details for leveling: 

  • Driveways: Regularly subjected to vehicle traffic, repair costs can range from $800 to $4,000. 
  • Patios: Mostly used for walking, the cost to lift a patio falls between $800 and $3,000. Porch repairs can exceed $5,000, particularly if extensive work like piering is necessary. 
  • Sidewalks: Essential for accessing homes and frequently used, leveling costs for sidewalks and paths can range from $500 to $2,000. 

Choosing leveling over replacement is often the preferred option for saving both time and money. 

Evaluating concrete damage early and opting for concrete leveling can be more cost-effective than replacement, especially with methods like PolyRenewal™, offering swift, less intrusive, and durable solutions.

Yes, concrete leveling is considered environmentally friendly because it uses less material than concrete replacement and extends the life of the existing concrete, thereby reducing waste. The material used is also non-toxic to the environment. 

The polyurethane foam injection method from Groundworks allows the surface to be used on the same day as the installation. The foam cures within 15 minutes. This is far more efficient than other methods like mudjacking, self-leveling concrete, or repouring, which can take hours or days to harden.
