Concrete Leveling: What Is It? Do You Need It?

Concrete is widely recognized for its strength and is used to build all kinds of useful structures, such as sidewalks, driveways, pool decks, and patios. Despite its strength, concrete can still suffer from damage and deterioration over time, necessitating appropriate repairs.

Concrete leveling offers a solution for addressing issues related to uneven or settled concrete surfaces. This guide aims to provide a comprehensive overview of concrete leveling, including its definition, operational mechanisms, and the various techniques employed.

Additionally, we will cover the circumstances that warrant concrete leveling, the professionals to contact for expert services, and the expenses associated with the procedure. This guide is designed to assist both homeowners and business owners in determining whether concrete leveling is a suitable repair option for their specific requirements

What is Concrete Leveling?

Concrete leveling is a repair method aimed at correcting uneven or sunken concrete surfaces. It involves elevating and straightening the concrete to return it to its initial position, thus mitigating risks associated with the irregularity. This technique enhances the safety, functionality, and visual appeal of the concrete space.

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 realigns uneven or settled concrete surfaces to their initial level, enhancing safety, functionality, and appearance. The technique employs four primary methods: polyurethane foam injection, stone slurry grout leveling, mudjacking, and application of self-leveling overlays, with the selection based on specific conditions and desired results.

Evaluating the state of your concrete surfaces is crucial to determine the necessity for leveling. If there’s noticeable unevenness, sinking, or potential tripping hazards, it’s wise to seek a professional’s assessment.

Even if your surfaces appear to be in satisfactory condition, consulting a professional can help ascertain whether leveling is advisable.

The cost of concrete leveling varies, influenced by the size of the area, the severity of the issue, the chosen repair technique, and the scope of the needed repairs. For a precise cost estimate, it’s recommended to obtain quotes from well-regarded companies.

Opting for concrete leveling can be more economical than complete replacement. Weighing the advantages and disadvantages, considering your specific needs, and consulting with experts will guide you in making 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

Injecting polyurethane foam is a quick and straightforward method used by professionals to raise and stabilize sinking concrete slabs.

This procedure involves pumping a lightweight polyurethane foam into the concrete through tiny holes that have been drilled. The foam then expands beneath the concrete, filling the voids between the slab and the soil, enabling precise adjustment and stabilization of the slab.

While you might be familiar with mudjacking, a somewhat similar technique, polyurethane leveling elevates the process to a more effective tier.

Unlike mudjacking, polyurethane foam injection doesn’t involve extensive drilling, doesn’t require a lengthy hardening period, and isn’t limited to a small area of concrete. It necessitates only minimal drilling of penny-sized holes, sets within 30 minutes, and thoroughly occupies the spaces between the sinking slabs and the ground.

Opting for polyurethane foam injections means you’ll enjoy greater value, a smoother surface finish, and more durable outcomes compared to other leveling methods.

2. Mudjacking

Mudjacking, also known as slabjacking, is a highly effective method for repairing uneven and sunken concrete slabs. This procedure involves injecting a specialized slurry mixture beneath the concrete slab.

The slurry mixture (a blend of water, soil, sand, and cement) transforms into a mud-like consistency, which is where the term “mudjacking” comes from. As the mixture hardens, it forms a robust and stable foundation that effectively fills voids, correcting the underlying issues that lead to concrete deformation.

Despite its effectiveness in numerous situations, mudjacking has its limitations. It may not be suitable for lifting slabs that support heavy partition walls, for instance. The precision required in such cases is difficult to achieve, potentially leading to uneven lifting and further complications.

Moreover, it’s crucial to understand that mudjacking is not a suitable project for the average homeowner. The procedure requires specialized knowledge, skills, and equipment to ensure it’s done safely and effectively.

Attempting mudjacking without the proper expertise can result in significant damage to your property. The complexity of the task means that instructional videos or online articles cannot provide the depth of knowledge necessary for successful execution.

DIY attempts not only risk exacerbating the initial problem but can also significantly increase the repair costs. For these reasons, it’s strongly advised to seek professional services when considering mudjacking as a solution to concrete issues.

3. Cement or Stone Slurry Concrete Leveling

Stone slurry grout concrete leveling merges the techniques of mudjacking and polyurethane foam injection, offering a unique and efficient method for correcting uneven concrete slabs. This innovative process utilizes a specially formulated mix of crushed stones, predominantly limestone, combined with water to create a dense, malleable slurry. This material is then precisely injected beneath the concrete using equipment akin to that used for polyurethane foam injection.

The procedure requires drilling large holes, approximately 1 inch in diameter, similar to those needed for mudjacking. However, one of the distinct advantages of stone slurry grout leveling is the enhanced control over the viscosity and distribution of the material.

This precision ensures a more uniform lift and stabilization of the concrete slabs. Moreover, the limestone and water mixture adds substantial weight, exerting additional pressure on the underlying soil, which helps to secure the slabs in place more effectively.

In contrast to traditional mudjacking, the stone slurry grout technique has the capability to fill voids completely, leaving no gaps and thus, providing a more stable and lasting solution. This method is also lauded for its environmental benefits, as it utilizes natural materials and minimizes waste.

Despite its numerous advantages, including durability and the complete filling of voids, stone slurry grout concrete leveling tends to be more costly than mudjacking. However, its long-term effectiveness and eco-friendly attributes make it a worthwhile investment for those seeking a reliable and sustainable approach to concrete leveling.

4. Self-Leveling Concrete

Self-leveling concrete, as its name suggests, is an accessible option for those undertaking DIY projects. This material is composed of polymer-enhanced cement, and its development over the years has significantly improved its user-friendliness. It distinguishes itself with its quick drying time, minimal water needs, and versatility with a variety of materials and finishes, enabling DIY enthusiasts to easily create smooth, level surfaces for patching or resurfacing interior floors.

Although it comes at a higher cost compared to traditional concrete, self-leveling products are specifically designed for smaller repair tasks and home improvement projects that require concrete but not necessarily structural reinforcement. What was once deemed a niche product has, through innovation, become a feasible choice for homeowners wishing to upgrade their concrete floors without breaking the bank.

However, it’s important to approach DIY projects involving self-leveling concrete with caution. Without proper knowledge and preparation, these endeavors can become hazardous and costly.

When to Level Your Concrete

There are numerous reasons why you might find yourself in need of concrete leveling services. For instance, if you’ve experienced damage to your vehicle due to an uneven driveway—a surprisingly common occurrence—it’s a clear signal that it’s time to explore concrete lifting solutions to repair the area promptly. Regularly traversing over dips and bumps in your garage or driveway can inflict significant harm on your car’s suspension and tires, escalating wear and tear alongside the need for maintenance.

The presence of cracked or uneven concrete surfaces is a telltale indicator that leveling is necessary. You might observe cracks on your basement floor, notice that steps appear misaligned, or spot fractures in the external brickwork, stonework, or siding of your home. It’s not unusual for chimneys to show signs of cracking or to begin detaching from the house itself

Beyond being an aesthetic concern that detracts from your property’s curb appeal, cracked and uneven concrete surfaces pose a considerable safety risk and potential liability. Uneven slabs are a tripping hazard that can lead to injuries, a risk that is particularly acute for the elderly and individuals with mobility challenges, and is especially hazardous around concrete pool decks.

To prevent these issues from escalating into major problems, it’s advisable to address concrete leveling needs at the earliest sign of trouble. Engaging with reputable local concrete leveling experts as soon as any irregularities are noticed or suspected in your property’s concrete is essential for maintaining both its appearance and safety.
