Concrete Leveling
Fast, affordable concrete lifting that eliminates trip hazards and restores your sunken slabs.

Why Concrete Slabs Sink and Settle
Sunken concrete creates dangerous trip hazards and looks terrible. You might notice sections of your driveway, sidewalk, or patio have settled lower than surrounding areas. This happens more often than most homeowners realize, and it is not necessarily a sign of poor original construction. Soil naturally shifts and settles over time, especially here in New England where we deal with freeze-thaw cycles, changing moisture levels, and soil erosion.
Several factors cause concrete to sink. Water washing away soil underneath creates voids that let concrete settle. Poor compaction during initial construction leaves soft spots that compress under the weight of the concrete. Tree roots growing underneath can lift or shift concrete, and when those roots die and decay, the concrete settles into the void. Whatever the cause, you end up with uneven surfaces that pose safety risks and reduce your property value. The good news is that concrete leveling provides a cost-effective solution that works much better than you might expect.
Common Signs You Need Concrete Leveling
- Visible height differences between concrete sections
- Trip hazards where slabs meet at uneven heights
- Water pooling on concrete surfaces after rain
- Gaps between concrete and foundation walls
- Tilted or sloping sections of walkways or patios
- Difficulty opening doors or gates over settled concrete
How We Lift and Level Sunken Concrete
Concrete leveling goes by several names including mudjacking, slabjacking, and polyurethane foam injection. All these methods accomplish the same goal of raising sunken concrete back to its original level. The process works by injecting material underneath the slab to fill voids and lift the concrete. This approach costs far less than tearing out and replacing the concrete, typically saving you 50 to 70 percent compared to replacement costs.
Mudjacking Process
Traditional mudjacking uses a cement-based slurry mixture pumped under pressure through holes drilled in the concrete. We drill strategic holes about 2 inches in diameter, then pump the slurry underneath until the slab lifts to the desired height. The mixture fills voids and compacts loose soil while raising the concrete. Once the slab reaches proper level, we patch the holes and clean up. The concrete is ready to use almost immediately after we finish.
Polyurethane Foam Lifting
Polyurethane foam injection represents newer technology that offers some advantages. The foam weighs much less than cement slurry, putting less stress on soil underneath. It expands precisely, giving us excellent control over how much we lift the slab. The foam cures quickly, often within 15 minutes, so you can use the surface right away. We drill smaller holes for foam injection, typically less than an inch in diameter, which makes repairs less noticeable. Both methods work well, and we help you choose the best option for your specific situation.
Why Choose Leveling Over Replacement
Many homeowners assume they need to replace sunken concrete, but leveling makes much more sense in most situations. The concrete itself is usually still in good condition. The problem is the soil underneath, not the slab itself. Lifting the existing concrete addresses the actual issue while saving you significant money. You also avoid the hassle and disruption of demolition and replacement.
Consider the practical advantages. Concrete leveling typically takes a few hours rather than several days required for replacement. You can use the surface almost immediately instead of waiting a week or more for new concrete to cure. There is no demolition debris to haul away. Your existing concrete often matches surrounding areas better than new concrete would. The cost savings alone make leveling attractive, but the convenience and speed seal the deal for most property owners.
When Replacement Makes More Sense
Leveling works best when the concrete is structurally sound despite being sunken. If your concrete has extensive cracking, significant surface damage, or is crumbling and deteriorating, replacement might be the better choice. Very thin slabs or sections broken into multiple pieces may not lift well. We evaluate your specific situation honestly and recommend the approach that makes the most sense for your property and budget. Sometimes we suggest lifting what we can and replacing only the worst sections, which still saves money compared to total replacement.
Where We Apply Concrete Leveling
Concrete leveling works for many different applications around your property. We regularly lift sunken driveway sections that create bumps when you drive in. Sidewalk trip hazards disappear when we bring sections back to even height. Settled patio slabs can be raised to create proper drainage and eliminate water pooling. Garage floors that have tilted away from the foundation get leveled to restore proper floor slope.
Common Leveling Projects
- Driveway aprons that have settled away from garages
- Sidewalk sections creating trip hazards
- Patio slabs that slope toward the house
- Pool deck areas that have become uneven
- Basement floor sections that have sunk
- Concrete steps that have pulled away from landings
The results often exceed expectations. Surfaces that were embarrassing eyesores or genuine safety hazards become level and functional again. Water drainage improves dramatically when proper slope is restored. Your property looks better and becomes safer for family and visitors. Many customers tell us they wish they had addressed the problem sooner instead of living with sunken concrete for years. The relatively low cost and quick turnaround make leveling one of the most satisfying home improvements you can do.
