Uneven concrete is more than just an eyesore. Sinking driveways, sidewalks, patios, and garage floors can create serious safety hazards and reduce the value of your property.
At Northwest Concrete Leveling, we specialize in lifting and stabilizing sunken concrete using advanced polyurethane foam injection. This modern method restores your concrete quickly and effectively without the cost, mess, or disruption of full replacement.
Most projects can be completed in just a few hours, and the surface is often ready for use the same day.




Concrete settles when the soil beneath the slab shifts, erodes, or becomes compacted over time. Several factors can contribute to this process, including:
When the ground beneath the slab loses support, the concrete begins to sink, tilt, or crack.
Northwest Concrete Leveling uses a high-density polyurethane foam injection process to lift and stabilize concrete slabs.
We inspect the affected area to determine the cause of settlement and identify voids beneath the slab.
Small holes are drilled into the slab where the foam will be injected.
Structural polyurethane foam is injected beneath the concrete where it expands to fill voids and lift the slab.
The slab is carefully raised back to its original position and stabilized.
Compared to traditional repair methods, polyurethane foam leveling offers several advantages:
• Faster installation
• Minimal drilling and disruption
• Lightweight but extremely strong material
• Long-lasting soil stabilization
• Most surfaces usable the same day
• Significantly cheaper than concrete replacement
For many homeowners and businesses, concrete leveling is the most efficient and cost-effective solution.
Northwest Concrete Leveling repairs and stabilizes many types of concrete surfaces, including:
