Sidewalk Leveling
Safe and Smooth Walkways
Uneven sidewalks aren’t just unsightly, they’re a major tripping hazard. At Spray Foam by IOK, we offer fast, reliable sidewalk leveling using high-density polyurethane foam to lift and stabilize concrete slabs. Our clean, non-invasive process restores safety and curb appeal in just hours.
Uneven Sidewalk? We've Got the Fix.
Sidewalks often shift due to soil erosion, water damage, tree roots, or freeze-thaw cycles. These changes create dangerous height differences between slabs. Our polyurethane injection process fills the void beneath the sunken section, lifting it back to a level surface without tearing out or replacing concrete.
What Causes Uneven Sidewalk Slabs?
-
Soil Erosion - Water washes away supporting soil.
-
Poor Compaction - Loose soil settles unevenly over time.
-
Tree Roots - Roots push up and crack concrete.
-
Freeze-Thaw Cycles - Expanding ice shifts the slab.
-
Heavy Loads - Excess weight causes sinking or cracking.
-
Drainage Issues - Trapped water weakens the soil base.

Our Process
Step One
DRILL
We drill small holes in sunken concrete.
Step Two
FILL
We inject expanding polyurethane foam.
Step Three
LIFT
The foam lifts and stabilizes the slab.
Once completed, we patch the holes we drilled and clean the surface of the slab. Your concrete is typically ready for normal use in under an hour.
