How Concrete Lifting Works
Polyurethane concrete lifting works by injecting expanding poly foam beneath a sinking slab. The foam fills empty spaces, strengthens weak soil, and gently lifts the concrete back to a level position. This process stabilizes the slab from below instead of replacing it from the top.
Concrete sinks when the soil underneath shifts, erodes, or compacts over time. Water runoff, poor drainage, and Colorado’s freeze-thaw cycles can wash out soil and create voids under driveways, patios, walkways, and garage floors.
Polyjacking and mudjacking are both forms of slabjacking, meaning they lift sinking concrete by filling the empty space underneath it. The difference is in the material used.
Mudjacking uses a heavy cement-based slurry to push the slab upward. Polyjacking uses lightweight polyurethane foam that expands beneath the slab. As the foam expands, it fills small voids, stabilizes weak soil, and gently lifts the concrete in a controlled way.
Because polyurethane foam is much lighter, it does not add extra weight to already unstable soil. Poly foam concrete leveling also requires smaller drill holes and typically allows the concrete to be used the same day.
Both methods lift concrete, but polyurethane foam offers a cleaner, more precise, and longer-lasting solution.
When done properly by an experienced concrete lifting contractor, the slab is raised in a controlled way. The goal is to gently return it to level without causing stress or damage.
What We Lift & Repair
We lift most structurally sound concrete slabs that have settled or become uneven.
For residential properties, that includes driveways, sidewalks and walkways, patios, porches, steps, garage floors, pool decks, and interior concrete floors.
We also provide commercial concrete leveling for sidewalks, warehouse floors, loading docks, parking areas, building entrances, and other high-traffic surfaces.
If the concrete is still intact but sinking, uneven, or pulling away due to soil movement underneath, it can often be lifted and stabilized without replacement. During your estimate, we’ll assess the condition of the slab and let you know if lifting is the right solution.
Yes. Driveway leveling is one of the most common services we provide. If sections of your driveway are uneven or sinking, we can lift and stabilize them without replacing the entire slab.
Yes. We level garage floors and interior concrete slabs that have settled or become uneven. Concrete stabilization under the slab helps prevent future sinking.
Yes. Sunken concrete steps and porch slabs can often be lifted and carefully realigned without tearing them out.
Uneven steps and porches are common trip hazards, especially near entryways. Using polyurethane foam injection, we lift the slab from underneath, stabilize the soil, and restore proper alignment. This helps improve safety, drainage, and the overall appearance of your entry — often in just a few hours.
If the concrete is structurally sound, lifting is usually a faster and more affordable option than full replacement.
Yes. In addition to residential concrete leveling, we provide professional commercial concrete lifting for sidewalks, building entrances, warehouse floors, loading docks, parking areas, and other high-traffic surfaces.
Uneven commercial concrete can create liability risks and disrupt daily operations. Our polyurethane foam lifting process allows us to stabilize and level slabs with minimal downtime. In many cases, areas can return to service the same day.
If the concrete is structurally sound but sinking due to soil movement, lifting is often a faster and more cost-effective solution than full replacement.
Pricing, Estimates & Warranty
Concrete leveling typically costs 50–70% less than tearing out and replacing the slab. The exact price depends on the size of the area, how much the concrete has settled, and how much void filling or stabilization is needed underneath.
Every project is different. During your estimate, we assess the condition of the slab and the soil below it so we can give you a clear, honest price. There’s no pressure and no obligation — just straightforward information so you can decide what makes sense for your property.
In most cases, yes. Concrete raising is typically 50–70% less expensive than tearing out and replacing the slab. Replacement involves demolition, hauling away debris, new concrete, labor, and waiting for it to cure. Concrete lifting avoids all of that.
Instead of starting over, we stabilize the soil underneath and lift the existing slab back into place. If the concrete is still structurally sound, raising it is often the more practical and cost-effective solution.
Yes. We provide free estimates and even allow photo uploads for virtual quotes. You do not always need to be home for an estimate.
We provide a 3-year warranty on qualifying concrete leveling projects. Warranty coverage depends on site conditions, soil stability, and proper drainage around the slab.
Because every property is different, we review those factors during your estimate and explain exactly what is covered. Our goal is to lift and stabilize your concrete the right way so it performs long-term — not just temporarily.
Concrete Raising vs. Full Replacement
Replacement is usually necessary when the concrete is structurally failing — such as when it is shattered into multiple loose pieces, severely deteriorated, or crumbling throughout the slab.
However, if the concrete is still intact and simply sinking or uneven due to soil movement underneath, lifting is often the better option. Concrete raising stabilizes the base and restores alignment without demolition. During your estimate, we’ll assess the condition of the slab and give you an honest recommendation based on what makes the most sense long-term.
Yes. When the soil beneath the slab is properly stabilized and voids are filled correctly, polyurethane concrete leveling provides strong, long-term support.
The key is addressing the problem underneath the concrete — not just the surface. By filling empty space and strengthening weak soil, the slab is supported more evenly. While no solution can control future soil movement entirely, lifting and stabilization is designed to prevent further settlement and extend the life of your concrete.
In many cases, yes. Concrete lifting keeps your original slab in place, which means the color and texture stay consistent with the rest of your surface. The small drill holes used during the lifting process are patched neatly and are far less noticeable than large replacement sections.
When concrete is replaced in sections, the new concrete rarely matches the old slab in color or finish. That can leave obvious patch lines. Lifting avoids that contrast and preserves the existing look of your driveway, patio, or walkway.
New concrete can still sink if the soil underneath is not properly stabilized. Replacement only gives you a new surface — it does not fix the weak or eroded soil below it.
Concrete raising focuses on the root cause. By filling voids and stabilizing the ground beneath the slab, we restore support where it’s needed. If the existing concrete is structurally sound, lifting is often the more practical and cost-effective solution.
What to Expect on Project Day
Most residential projects are completed in just a few hours, depending on the size of the slab and how much lifting is needed.
In most cases, the slab can be walked on or driven on the same day. Polyurethane foam expands and cures quickly, which allows the concrete to regain support almost immediately.
Unlike replacement, there is no long waiting period for new concrete to cure. Once the lifting is complete and the holes are patched, the area is typically ready for normal use within hours.
No. The process is clean and controlled. We drill small 5/8″ holes in targeted areas, inject polyurethane foam beneath the slab, and patch the holes neatly once the concrete is level.
There is no demolition, no tearing out large sections, and no heavy equipment running across your property. Most homeowners are surprised at how minimal the disruption is compared to full concrete replacement.
Not always. As long as we have clear access to the area, many homeowners choose not to be present during the project.
Why Homeowners Choose Liftwerx
Liftwerx is a local, owner-operated concrete lifting company based in Johnstown. When you call, you speak directly to someone involved in the work.
Yes. The polyurethane foam used for concrete lifting is designed specifically for structural stabilization. Once injected beneath the slab, it expands, cures quickly, and becomes inert.
The material stays below the concrete surface and is not exposed once the process is complete. When installed properly, it provides strong support while remaining a safe and effective solution for residential and commercial concrete leveling.
Look for experience, clear communication, and honest pricing. A good concrete leveling contractor will explain your options and not push replacement if lifting will fix the problem.
Concrete raising reduces waste by keeping existing slabs in place. It avoids hauling debris to landfills and minimizes new material use.
