Professional Concrete Raising, Slab Leveling & Concrete Repair
Uneven concrete isn’t just an eyesore — it’s a safety hazard. Sunken driveways, cracked sidewalks, and sinking patios can create trip hazards, damage vehicles, and lower your property’s value. Professional concrete leveling offers a fast, cost-effective alternative to full concrete replacement, restoring your surfaces in hours instead of days.
At Sundahl Waterproofing, we provide expert concrete leveling services designed to lift, stabilize, and restore your existing concrete. Our process corrects sunken slabs, fills voids beneath the surface, and returns your concrete to a safe, level position — often at half the cost of replacement.
What Is Concrete Leveling?
Concrete leveling is a repair method that raises and stabilizes sunken concrete by addressing the soil or voids beneath the slab. Instead of removing and replacing the concrete, material is injected underneath to lift it back into position. This process is commonly used for residential and commercial surfaces including driveways, sidewalks, patios, and garage floors.
Common Causes of Sunken Concrete
Concrete settles over time due to several factors:
- Soil erosion beneath slabs
- Freeze-thaw cycles and seasonal ground movement
- Poorly compacted fill soil
- Water runoff washing out support soil
- Heavy loads on driveways and walkways
- Tree roots shifting concrete
- Foundation settlement
These issues create voids under the slab, allowing concrete to sink, crack, or become uneven.
Benefits of Concrete Leveling vs. Replacement
Concrete leveling is one of the most efficient ways to repair uneven surfaces. Advantages include:
Cost-Effective Repair
Concrete leveling typically costs significantly less than tearing out and replacing concrete, making it a budget-friendly solution.
Fast Installation
Most projects can be completed in hours, and surfaces are often ready for use the same day.
Minimal Disruption
No demolition, heavy machinery, or long curing times.
Improves Safety
Eliminates trip hazards on sidewalks, steps, and walkways.
Extends Concrete Life
Stabilizes existing slabs and prevents further cracking.
Environmentally Friendly
Keeps old concrete out of landfills and reduces material waste.

Signs You Need Concrete Leveling
You may benefit from concrete leveling if you notice:
- Uneven or tilted slabs
- Cracks in driveways or sidewalks
- Water pooling on concrete surfaces
- Trip hazards around your home
- Sunken steps or porch slabs
- Gaps under concrete slabs
- Garage floors sloping toward foundation
Addressing these issues early helps prevent further settlement and costly repairs.
Our Concrete Leveling Process
Our professional concrete raising process is designed for precision and long-lasting results.
Step 1: Inspection
We evaluate the slab, soil conditions, and level of settlement.
Step 2: Small Injection Holes
Small holes are drilled into the concrete at strategic points.
Step 3: Material Injection
Specialized material is pumped beneath the slab to fill voids and lift concrete.
Step 4: Precision Leveling
We carefully raise the slab to the proper height.
Step 5: Patch & Clean
Injection holes are sealed and the surface is cleaned.
Most projects are completed quickly, and concrete can often be used immediately after leveling.
Why Concrete Sinks in the Northeast
Cold winters and fluctuating moisture levels cause soil expansion and contraction, leading to shifting ground beneath concrete surfaces. Over time, this movement causes slabs to settle unevenly and crack. Professional leveling restores stability without full replacement.
Concrete Leveling vs. Concrete Replacement
| Concrete Leveling | Concrete Replacement |
|---|---|
| Lower cost | Expensive |
| Same-day use | Days of curing |
| Minimal disruption | Major demolition |
| Preserves existing slab | Removes entire surface |
| Fast installation | Multi-day project |
| Environmentally friendly | Waste to landfill |
In many cases, leveling provides the same visual result as new concrete at a fraction of the cost.
