In this blog, we’ll explain the key differences between concrete grinding and polyurethane concrete leveling, highlight their ideal applications, and help you determine which option is best for your project. Keep reading to explore these two popular concrete repair methods!
What Is Concrete Grinding?
Concrete grinding is a technique used to smooth and level uneven concrete surfaces by using specialized machinery. With concrete grinding, you are essentially sanding down the top layer of concrete, which is often rough and uneven. These machines are equipped with diamond-impregnated blades or discs that grind away the top layer of the concrete, removing rough patches, imperfections, trip hazards, and inconsistencies. This method can be applied to old and newly poured concrete, improving its appearance and usability. Concrete grinding is commonly used on driveways, walkways, patios, and floors that need a more polished or even surface.
What Is Polyurethane Concrete Leveling?
Polyurethane concrete leveling, often called polyjacking, is a modern method for lifting and leveling uneven or sunken concrete. This repair process involves injecting a polyurethane foam beneath the affected concrete. As the foam expands, it fills voids and lifts the slab back to its original position. This method is often used on driveways, patios, walkways, and garage floors to correct settling issues. It is valued as quick, minimally disruptive, and highly cost-effective compared to full concrete replacement.
Applications Of Concrete Grinding
Concrete grinding is a highly effective process used in many applications to enhance the functionality and appearance of concrete surfaces.
- Driveways: Over time, driveways can develop cracks, rough patches, and uneven areas due to wear and tear or shifting ground. Concrete grinding removes these surface imperfections, creating a smooth and polished appearance.
- Walkways: Uneven walkways can pose a significant safety hazard, especially for pedestrians. Concrete grinding levels out these raised areas, eliminating tripping hazards and ensuring a smooth, safe walking surface. It is commonly used in residential and public walkways to improve accessibility and safety.
- Patios: Outdoor patios often develop stains, discoloration, and uneven spots due to exposure to the elements. Concrete grinding can refresh the look of your patio by removing these imperfections, leaving behind a smooth and visually appealing surface. This process also prepares the area for additional treatments like sealing or staining, making your patio more durable and attractive.
- Garage Floors: Garage floors often suffer from oil stains, tire marks, and uneven sections caused by constant use. Concrete grinding removes these stains and levels the surface, providing a clean, smooth, and functional space.
- Commercial Spaces: In commercial environments like warehouses, shopping centers, and office buildings, the appearance and safety of concrete surfaces are critical. Concrete grinding can improve the overall look of these areas by eliminating imperfections and leveling the floors, reducing the risk of accidents and making the space more visually appealing for customers and employees.
- Industrial Settings: In factories and manufacturing plants, concrete surfaces need to be smooth and even to ensure the proper functioning of machinery and the safety of workers. Concrete grinding is often used in industrial settings to prepare floors for specialized coatings or treatments, providing a durable, level surface that can withstand heavy use and harsh conditions.
Applications Of Polyurethane Concrete Leveling
Polyurethane concrete leveling, or polyjacking, is an innovative solution to lift and stabilize uneven concrete surfaces.
Here are the key applications of polyurethane concrete leveling:
- Driveways: Over time, driveways can sink or become uneven due to soil erosion or ground movement, creating unsightly dips and potential hazards for vehicles and pedestrians. Polyurethane leveling raises these uneven sections, restoring the driveway’s smooth surface.
- Walkways and Sidewalks: Uneven walkways and sidewalks are common tripping hazards, especially in areas with frequent foot traffic. Polyurethane leveling lifts and stabilizes sunken sections, eliminating dangerous height differences between slabs. This is a popular solution for homeowners, municipalities, and businesses seeking to maintain safe, accessible walkways without needing costly concrete replacement.
- Patios and Porches: Patios and porches can settle unevenly over time, leading to sloped or recessed areas that detract from the outdoor living space’s functionality and appearance. Polyurethane concrete leveling restores the surface, making these areas more visually appealing and functional for outdoor activities, furniture placement, and gatherings. This method also helps prevent further structural issues by addressing underlying soil movement.
- Garage Floors: Garage floors are prone to settling, especially under the weight of vehicles and equipment. Uneven or sloping floors can cause problems with drainage and create trip hazards. Polyurethane leveling provides a quick and effective way to stabilize the floor, restoring a smooth, level surface. It’s an ideal solution for homeowners seeking to improve the usability and safety of their garage space without invasive excavation work.
- Pool Decks: Pool decks can shift and sink over time due to soil movement, leading to dangerous uneven surfaces that can pose safety risks for swimmers. Polyurethane leveling lifts and levels hollow sections of the pool deck, restoring a safe, smooth walking surface. This method also helps to prevent water from accumulating in low areas, which can cause additional damage to both the deck and pool structure.
- Foundation Slabs: Minor foundation settlement and movement can cause floors to become uneven, leading to structural concerns. Polyurethane concrete leveling effectively addresses these issues by filling voids beneath the slab and stabilizing it. While it’s not a replacement for major foundation repairs, this method can help mitigate minor settlement problems, preserving the structure’s integrity.
- Warehouse Floors: In commercial and industrial environments, floors must withstand heavy machinery and constant traffic. Over time, warehouse floors can become uneven, affecting the safety and efficiency of the workspace. Polyurethane leveling restores the evenness of the floor, ensuring safe conditions for workers and machinery operations.

Which Is Better: Concrete Grinding vs. Polyurethane Concrete Leveling?
Whether to use concrete grinding or polyjacking depends on the cause, what you want to achieve, and whether the issue is mainly surface-level or structural. Concrete grinding is mainly cosmetic and does not address underlying issues in the soil or subgrade. It only works on surface-level problems and does not resolve deeper structural issues. So, if you want to improve the appearance of your concrete, grinding is a good option.
However, polyurethane jacking may be more appropriate if you have structural issues such as sinking slabs or uneven surfaces. It can also be used to repair cracks in concrete, which are often caused by soil movement or settlement. If the issue in your concrete is structural, it’s better to perform polyjacking. While concrete grinding can be a short-term solution, the underlying issue will come back, and the problem will continue to worsen.
