Cracked or sunken concrete is a common problem for homeowners and businesses alike. Whether it’s a sloping sidewalk, uneven driveway, or settling patio, damaged concrete not only looks bad, but it also creates safety hazards and potential liability issues.
But once you spot the problem, you’re faced with a big decision: Should you go for concrete lifting or a full replacement?
In this article, we’ll compare concrete lifting vs. replacement in terms of speed, cost, cleanliness, and long-term durability so you can choose the right fix for your property and your budget.
What Is Concrete Lifting?
Concrete lifting, sometimes called slab jacking or mudjacking, is a process used to raise and level sunken concrete surfaces without tearing them out. It involves drilling small holes in the slab and pumping a special material, such as polyurethane foam or a cement-based slurry, beneath the surface. As the material expands, it lifts the slab back to its original position.
This method is ideal for:
- Sunken sidewalks
- Uneven driveways
- Tilting patios
- Garage floors or basement slabs
- Pool decks
Concrete lifting is fast, minimally invasive, and significantly more affordable than full replacement in most cases.
When Is Concrete Replacement Necessary?
Concrete replacement involves removing the old slab entirely and pouring a brand-new one. This process is much more labor-intensive and time-consuming, but sometimes necessary if the original concrete is severely cracked, broken, or deteriorated beyond repair.
Replacement is typically recommended when:
- Cracks are wide, deep, or multiple
- Concrete has significant spalling (surface breakdown)
- The slab has sunk too far to be safely lifted
- The sub-base is unstable or washed out
While replacement offers a fresh, clean look, it comes with higher costs, more downtime, and a longer, messier process.
Concrete Lifting vs. Replacement: Key Comparisons
Let’s break it down by the factors that matter most to property owners.
Speed
- Concrete Lifting: Most projects are completed in a few hours, and the area is ready for use within 24 hours.
- Replacement: Can take several days or more, including demolition, framing, pouring, and curing (which can take up to 7 days).
Cost
- Concrete Lifting: On average, lifting costs 30–50% less than replacing the same slab.
- Replacement: Higher due to demolition, disposal, labor, and materials.
Mess and Disruption
- Concrete Lifting: Involves small drill holes and minimal cleanup. No heavy demolition equipment needed.
- Replacement: Requires jackhammers, large equipment, debris removal, and noise.
Longevity
- Concrete Lifting: Typically lasts 5–10 years, depending on the soil and material used.
- Replacement: A new slab can last 20+ years if installed properly.
Environmental Impact
- Concrete Lifting: Reuses existing concrete, reducing waste and carbon emissions.
- Replacement: Involves the disposal of old concrete and the production of new materials.
Which Is Right for You?
If your concrete is in generally good shape but has settled due to poor soil conditions or freeze-thaw cycles, concrete lifting is the smarter, faster, and cleaner solution. But if the slab is crumbling, badly cracked, or shows signs of structural failure, replacement is the only safe option.

FAQs About Concrete Lifting and Replacement
What Is the Average Cost of Concrete Lifting?
Concrete lifting usually costs between $5 and $15 per square foot, depending on the size and condition of the area. It’s much more affordable than replacement, which can cost $8 to $20+ per square foot. Larger or more complex lifting projects may cost slightly more. Always get a professional quote for accuracy.
How Long Does Concrete Lifting Last?
When done correctly, concrete lifting can last 5 to 10 years or more. The longevity depends on the quality of the fill material, local soil conditions, and moisture levels. Polyurethane lifting generally lasts longer than traditional mudjacking. Regular maintenance and proper drainage help extend its life.
Can All Sinking Concrete Be Lifted?
Not always. Concrete that is heavily cracked, severely deteriorated, or sitting on extremely unstable soil may not be a good candidate for lifting. A professional inspection is necessary to assess the slab’s condition. In some cases, replacement may be the only safe option.
Is Concrete Lifting Safe for Residential Areas?
Yes, it’s a safe and non-invasive process ideal for residential sidewalks, patios, garages, and driveways. Since it involves minimal noise and mess, your property stays functional during the repair. It also improves safety by eliminating trip hazards. Best of all, it’s completed quickly with little disruption.
What Material Is Used in Concrete Lifting?
Two main materials are used: cement-based slurry (mudjacking) and polyurethane foam. Mudjacking is heavier and more traditional, while polyurethane is lightweight, durable, and water-resistant. Both options have their pros and cons depending on the situation. Your contractor will recommend the best choice for your property.
