Concrete Leveling Process
Concrete Leveling Process SEE HOW SUNKEN CONCRETE GETS LIFTED How Does Mudjacking Lift Sunken Concrete? When concrete starts to sink, the problem is usually underneath the slab. Soil can settle, wash away, shrink, or lose support over time. As that support changes, driveways, sidewalks, patios, garage floors, and other concrete slabs can begin to drop or become uneven. St. Louis Mudjacking uses a proven grout-based process to fill unsupported areas beneath the concrete and carefully raise settled slabs back toward the proper level. https://mudjackingstlouis.com/wp-content/uploads/2026/08/Garage-Floor-Leveling-Near-Me.mp4 Our 3-Step Mudjacking Process How Mudjacking Works Drill & Prepare Small access holes are drilled through the settled concrete in carefully selected locations. These holes allow us to reach the empty or weakened areas beneath the slab. The number and placement of the holes depend on the size of the concrete, how it has settled, and where support is needed. The goal is to create access without removing the existing slab. Read More Pump & Level A grout-based mudjacking mixture is pumped beneath the concrete through the access holes. As the material moves beneath the slab, it fills voids and restores support in areas where the soil has settled or washed away. Controlled pressure is used to gradually raise the concrete. The slab is not simply forced upward all at once. The lifting is done carefully so the concrete can be brought back toward the proper position as evenly as possible. This is the part of the process that does the actual lifting. Read More Patch & Finish Once the slab has been raised to the appropriate position, the pumping stops. The access holes are then patched, and the work area is cleaned up. The patches may remain visible, especially on older concrete, but the goal is to leave the surface neat and usable. Read More What Happens Before the Lifting Starts? Before any material is pumped beneath the slab, the concrete needs to be evaluated. We look at the condition of the slab, how far it has settled, where the low areas are, and whether the concrete appears solid enough to lift. Not every slab is a good candidate for mudjacking. Concrete that is badly cracked, crumbling, or structurally worn out may be better suited for replacement. If lifting does not make sense, we will tell you. Common areas we evaluate include: Driveways Sidewalks and walkways Patios Garage floors Porches Steps and entry areas Pool decks Concrete slabs Commercial walkways and exterior concrete Areas with visible voids beneath the slab If you are dealing with a specific problem, you can also learn more about Driveway Leveling, Sidewalk & Walkway Lifting, and Concrete Slab Lifting. What Is Pumped Under the Concrete? Mudjacking uses a grout-based mixture that is pumped beneath the slab. The material is designed to fill unsupported areas and provide support beneath the concrete while the slab is being raised. This is different from simply filling a crack at the surface. The repair works from underneath the slab, where the loss of support originally caused the settlement. Why Concrete Needs Support From Below Concrete is strong, but it still depends on the ground underneath it. When that support disappears, the slab may begin to sink even if the concrete itself is still in good condition. Common reasons support is lost include: Soil settlement over time Poorly compacted fill beneath the original slab Clay soil movement as moisture levels change Water washout beneath concrete Drainage problems around the property Freeze-thaw cycles that contribute to soil movement Voids beneath slabs that leave sections unsupported These conditions are common throughout the St. Louis area, where clay-heavy soil and changing weather can affect the ground beneath concrete. How Long Does the Mudjacking Process Take? The amount of time depends on the size of the project, the number of slabs being lifted, and how much settlement has occurred. Smaller jobs may be completed relatively quickly. Larger or more complicated projects can take longer. Because mudjacking works with the existing concrete, it can often involve less disruption than tearing out and replacing the slab. What Can Mudjacking Help Correct? Mudjacking can be useful when the slab is still structurally sound but has settled out of position. It may help with: Uneven slab edges Trip hazards Low sections of driveways Settled sidewalks Patio slabs that have dropped Garage floor sections that are no longer level Porch or entry slabs that have settled Pool deck sections with uneven transitions Commercial walkways and concrete areas Voids beneath existing concrete For unsupported areas where lifting may not be the main goal, see our Void Filling service. 15+ Years of Experience 1000+ Projects Completed St. Louis Local & Family-Owned 100% Committed to Quality What Should You Expect After Mudjacking? The main goal is to improve the position and usability of the existing slab. Mudjacking may help: Reduce uneven transitions Correct certain trip hazards Restore support beneath the concrete Improve low spots Improve certain drainage problems caused by settlement Make driveways, sidewalks, patios, and other surfaces easier to use It is important to have realistic expectations. Mudjacking does not make old concrete new again. Existing stains, cracks, discoloration, and normal surface wear will still be there after the slab is lifted. What changes is the position of the concrete. When Is Mudjacking Not the Right Solution? Mudjacking is designed to lift concrete that has settled. It does not repair concrete that is already badly deteriorated. Replacement may make more sense when the slab has: Extensive cracking Severe surface deterioration Crumbling concrete Major structural damage Large broken sections Damage that prevents the slab from lifting as a unit We would rather give you a straightforward answer than recommend lifting concrete that is no longer worth saving.

FAQs
Mudjacking FAQs STRAIGHT ANSWERS ABOUT SUNKEN CONCRETE Questions About Mudjacking? We’re Here to Help. If your driveway, sidewalk, patio, porch, or other concrete slab has started to sink, it is normal to have questions before deciding what to do next. This page covers common questions about mudjacking, concrete settlement, the lifting process, and what property owners around St. Louis can expect. Our goal is simple: give you clear information so you can make the right decision for your concrete. https://mudjackingstlouis.com/wp-content/uploads/2026/02/Pool-Deck-Leveling.mp4 How Our Concrete Lifting Process Works How does concrete lifting actually work? Concrete lifting is a process where we restore sunken or uneven concrete by injecting polyurethane foam beneath the slab. We drill small holes, then inject the foam, which expands to fill empty spaces (voids) and gently lifts the concrete back to a level position. At the same time, it stabilizes the soil underneath so the problem doesn’t continue. You can see a full breakdown here: Concrete Leveling Process Why do you use polyurethane foam instead of traditional methods? Polyurethane foam is lightweight, strong, and designed to last. Unlike older mudjacking methods, it doesn’t add heavy weight to already weak soil. It also expands to fill small gaps, resists water, and cures quickly. This allows for a cleaner, more precise lift and long-term stability. You can compare both methods here: Poly Leveling vs Mudjacking Will lifting fix the root cause of the problem? Yes, in most cases. The main reason concrete sinks is because of empty space under the slab caused by soil erosion or settling. Our process fills those voids and stabilizes the base, not just the surface. That’s why we often include void filling as part of the repair: Void Filling Is concrete lifting a long-term solution? When done correctly, concrete lifting provides long-lasting results. The foam we use is designed to hold its shape, resist moisture, and support the slab for years. While no repair can guarantee zero movement forever, this method is one of the most reliable ways to fix sinking concrete without replacement. Pricing, Estimates & Getting Started How much does concrete leveling cost? The cost depends on several factors, including how much the concrete has sunk, the size of the area, and the condition of the soil underneath. In most cases, concrete leveling costs significantly less than full replacement because you’re not paying for demolition, hauling, or new concrete. The best way to get accurate pricing is to request a free estimate: Contact Us Do you offer free estimates? Yes, we provide free, no-obligation estimates for all projects. We’ll assess the problem, explain what’s causing it, and recommend the best solution so you can make an informed decision. Can I get a quote without being home? Absolutely. We offer virtual estimates to make things easy. You can send photos of your driveway, patio, sidewalk, or other problem areas, and we’ll review them and provide guidance. Start here: Request a Free Estimate Is concrete lifting really worth it compared to replacement? In most situations, yes. Lifting allows you to fix the problem quickly and at a lower cost while keeping your existing concrete. Replacement is more expensive, takes longer, and can be disruptive. Lifting is the smarter option when the concrete is still structurally sound. What to Expect on Project Day How long does a typical concrete lifting job take? Most jobs are completed in just a few hours, depending on the size and condition of the area. Smaller residential projects like driveways or sidewalks are often finished the same day. When can I use my concrete again? One of the biggest benefits of polyurethane foam is how quickly it cures. In most cases, your concrete is ready to use immediately after the work is completed. Will there be a mess or damage to my property? No, the process is clean and minimally invasive. We drill small holes (about the size of a coin), complete the lifting, and patch them so they blend in. There’s no heavy equipment, no large demolition, and minimal disruption. Do I need to do anything before you arrive? In most cases, we just ask that you clear the area so we can access the concrete. If there are any special requirements, we’ll let you know ahead of time so everything goes smoothly. What Surfaces Can Be Lifted & Repaired What types of concrete can you lift? We can lift and level a wide range of concrete surfaces including driveways, garage floors, sidewalks and walkways, patios, and pool decks. Do you handle both residential and commercial projects?

Yes, we also provide additional services to help protect your concrete long-term, including: Concrete Caulking / Foam Insulation Concrete Leveling vs Replacement Is concrete lifting better than replacing concrete? In many cases, yes. Lifting is faster, more affordable, and far less disruptive. Instead of removing and repouring concrete, we restore what you already have. This saves time, reduces waste, and gets your surface back to use much quicker. When is replacement the better option? Replacement may be necessary if the concrete is severely damaged, crumbling, or beyond repair. If the slab is still in good condition but uneven, lifting is usually the better choice. Will lifting fix cracks in concrete? Lifting can help stabilize the slab and prevent cracks from getting worse. However, sealing joints and cracks may also be needed to protect against water damage: Concrete Caulking How long will the results last? Polyurethane foam is designed for durability and long-term performance. It resists moisture and erosion, helping your concrete stay level for years when properly installed.
