Concrete lifting fixes sunken or uneven concrete slabs by raising them back to their original position without removal or replacement. This process eliminates trip hazards, improves drainage, restores proper function to driveways and walkways, and prevents further damage to your property’s concrete surfaces. The repair typically takes just a few hours compared to days or weeks for concrete replacement.
The procedure works by injecting material beneath the concrete to fill voids and lift the slab to its proper level. Professional concrete lifting services improves both the appearance and functionality of your concrete surfaces while costing 50-70% less than full replacement. Modern lifting methods cause minimal disruption to your property and allow immediate use of the repaired area.
Common Concrete Lifting Methods
Different lifting techniques work best for specific situations:
| Method | Best For | Materials Used | Average Cost | Cure Time | Durability |
|---|---|---|---|---|---|
| Mudjacking | Large slabs, stable soil | Cement slurry | $3-$6 per sq ft | 24-48 hours | 5-7 years |
| Polyurethane Foam | Precision lifting, smaller holes | Expanding foam | $5-$8 per sq ft | 15-30 minutes | 10+ years |
| Limestone Grout | Heavy-duty applications | Limestone mixture | $4-$7 per sq ft | 1-2 days | 8-10 years |
| Sand-Cement Mix | Economical repairs | Sand-cement blend | $2-$5 per sq ft | 2-3 days | 3-5 years |
Signs Your Property Needs Concrete Lifting
Recognizing these warning signs helps you address problems before they worsen:
- Uneven concrete surfaces creating trip hazards
- Water pooling on concrete after rain
- Gaps between slabs or between concrete and adjacent structures
- Cracking that appears alongside sunken areas
- Doors or gates dragging across concrete surfaces
- Tilted or sloped concrete that was originally level
Bonus Tip: To check if your concrete needs lifting, place a marble or ball on the surface. If it rolls in a direction it shouldn’t, your concrete likely has settlement issues that need addressing.

According to industry data, concrete lifting projects have increased by 27% over the last five years as property owners discover that lifting offers a more economical and environmentally friendly alternative to replacement. The average concrete replacement generates about 1,200 pounds of waste per 100 square feet, while lifting creates virtually no waste.
Benefits of Concrete Lifting for Different Property Areas
Driveways
Lifting restores proper drainage and prevents further cracking in driveways. This eliminates water pooling that can lead to:
- Freeze-thaw cycle damage
- Oil stain accumulation
- Additional settling from water erosion
- Damage to vehicle suspension systems
Sidewalks and Walkways
Lifting eliminates dangerous trip hazards and liability issues from uneven sidewalks:
- Restores ADA compliance for slope and level changes
- Prevents injuries from falls on uneven surfaces
- Improves appearance and property value
- Avoids potential legal issues from visitor injuries
Patios and Pool Decks
Lifting fixes drainage issues that affect outdoor living spaces:
- Eliminates puddles and standing water around pools
- Restores proper slope away from home foundation
- Prevents damage to patio furniture from wobbling
- Creates safer surfaces for bare feet around pools
Foundation Support
Lifting can address certain foundation-related issues:
- Realigns garage floors with foundation walls
- Corrects porches and stoops that have pulled away from homes
- Restores proper drainage around foundation perimeters
- Prevents water intrusion into basements or crawlspaces
Things to Consider Before Making a Decision
Before choosing concrete lifting for your property:
- Age and Condition of Concrete: Severely cracked or deteriorated concrete may need replacement instead of lifting. Concrete should be structurally sound despite being sunken.
- Cause of Settlement: Understand what caused the sinking to ensure lifting will provide a lasting solution. Ongoing soil issues may require additional remediation.
- Desired Longevity: Different lifting methods offer different lifespans. Consider how long you need the repair to last when selecting a method.
- Property Access: Equipment needs adequate access to your concrete. Tight spaces might limit method options or increase costs.
- Budget Constraints: While all lifting methods cost less than replacement, prices vary between techniques. Get quotes for multiple methods if appropriate.
Bonus Tip: Always address drainage issues at the same time as concrete lifting. Without proper drainage correction, the same water problems may cause renewed settling after your repair is complete.
Concrete Lifting Process
Understanding the lifting process helps set realistic expectations:
- Assessment: Technicians evaluate the concrete settlement pattern and cause
- Hole Drilling: Small access holes are drilled through the concrete (size depends on method)
- Material Injection: Lifting material is pumped under the slab until it rises to the desired level
- Precision Monitoring: Technicians use levels to ensure proper elevation of all areas
- Hole Patching: Access holes are filled with concrete patch material
- Site Cleanup: Equipment and materials are removed, leaving area ready for use
The entire process typically takes 2-4 hours for an average driveway or sidewalk, compared to 2-7 days for concrete replacement.
Concrete Lifting FAQ
How long does concrete lifting last?
Concrete lifting typically lasts 5-10+ years depending on the method used and underlying soil conditions. Polyurethane foam generally lasts longest (10+ years) because it’s lightweight and won’t wash away. Mudjacking often lasts 5-7 years under normal conditions. The longevity also depends on addressing the original cause of settlement and maintaining proper drainage.
Can all concrete be lifted, or are there limitations?
Most concrete slabs can be lifted, but there are limitations. Concrete must be structurally sound without severe cracking or disintegration. Very heavy structures may require specialized lifting techniques. Concrete that has broken into multiple pieces often needs replacement instead. Additionally, if the underlying soil has severe ongoing issues (like sinkholes), additional soil stabilization may be needed before lifting.
Will concrete lifting fix cracks in my concrete?
Concrete lifting addresses the settlement that often causes cracks but doesn’t repair existing cracks directly. Small cracks (1/4 inch or less) typically remain after lifting but can be filled separately. Large cracks or multiple broken pieces may indicate that replacement is a better option. Some lifting contractors offer crack sealing as an additional service after completing the lifting process.
Is concrete lifting a permanent fix?
While not technically permanent, concrete lifting provides a long-term solution that often lasts for many years. The true longevity depends on addressing the underlying cause of settlement. If the original settlement was caused by normal soil compaction, lifting typically provides a lasting fix. If ongoing issues like water erosion, tree roots, or expanding/contracting soils aren’t addressed, even lifted concrete may eventually settle again.
How soon can I use my concrete after lifting?
Usage time varies by method. Polyurethane foam lifting allows immediate use (within 15-30 minutes). Traditional mudjacking typically requires 24-48 hours before supporting heavy loads like vehicles. During hot weather, curing times may be shorter, while cold weather can extend them. Your contractor will provide specific guidelines based on the materials used and weather conditions.
Make the Right Decision
Professional Concrete lifting contractors offer a cost-effective, quick, and environmentally friendly way to restore your property’s functionality without the mess and expense of replacement. By raising sunken concrete back to its original position, you eliminate trip hazards, improve drainage, restore appearance, and prevent further damage.
Evaluate your specific concrete issues carefully, considering the age and condition of your concrete, the underlying cause of settlement, and your budget constraints. Choose a lifting method that addresses your particular needs and provides the longevity you require. With proper assessment and professional application, concrete lifting can add years of renewed functionality to your property’s concrete surfaces.
