Uneven sidewalks and walkways are more than just an inconvenience — they can create serious trip hazards and safety concerns for homeowners, businesses, and pedestrians.
Over time, sidewalks often sink or shift due to soil erosion, water drainage, or natural settling. When sections of concrete become uneven, they can create dangerous height differences that lead to accidents or liability issues.
Northwest Concrete Leveling provides professional sidewalk repair using advanced polyurethane foam injection. This modern repair method lifts and stabilizes sunken sidewalks quickly without the need for costly replacement.
Most sidewalk leveling projects can be completed in just a few hours, and the repaired surface is often ready for use the same day.
Sidewalks are constantly exposed to environmental conditions and shifting soil beneath the concrete. Over time, these factors can cause sections of the walkway to sink or move out of alignment.
Common causes include:
When the soil beneath the sidewalk loses support, the concrete slab can begin to sink, tilt, or crack.
Northwest Concrete Leveling uses a high-density polyurethane foam injection process to lift and stabilize uneven sidewalks.
We inspect the sidewalk to determine the cause of settlement and identify voids beneath the concrete.
Small holes are drilled into the slab where the foam will be injected.
Structural polyurethane foam is injected beneath the sidewalk where it expands to fill voids and gently raise the slab.
The concrete is carefully lifted back into position and stabilized.
This process restores the sidewalk while minimizing disruption to your property.
Compared to traditional concrete replacement, polyurethane foam leveling offers several advantages:
• Faster installation
• Minimal drilling and disruption
• Lightweight but extremely strong material
• Long-lasting stabilization
• Most sidewalks usable the same day
• Much more affordable than replacement
For many property owners, sidewalk leveling is the fastest and most effective way to eliminate dangerous trip hazards.
