Driveways & Garage Aprons
Backfill soil right next to the garage foundation frequently settles, creating a sharp bump at the garage door threshold. High-density polyurethane foam lifts the apron flush and supports vehicle weight within 30 minutes.
Polyurethane Foam Slabjacking
Concrete Leveling & Slabjacking in South Bend, IN
Freeze-thaw cycles and downspout washout in South Bend often leave driveways, front steps, sidewalks, patios, and interior slabs uneven or pitching water back toward the foundation. As a trusted local referral service, FOUNDATION WORKS connects you with independent specialists who lift sunken concrete with structural polyurethane foam.
Where Polyurethane Slab Leveling Works Best
Expanding closed-cell polymer fills sub-slab voids and lifts concrete back to grade without demolition.
Sidewalks, Walkways & Stoops
Sunken walkway panels create tripping hazards and collect winter ice. Penny-sized injection ports allow contractors to level steps and sidewalks cleanly in a single visit.
Patios & Pool Decks
When a backyard patio settles toward the house, rainwater runs straight against the foundation wall. Lifting the slab restores positive drainage away from your basement or crawl space.
Interior Basement & Warehouse Slabs
Hollow voids under interior floor slabs can cause cracking and uneven flooring. Foam injection stabilizes the subgrade and seals joints against moisture movement.
Slabjacking vs. Structural Foundation Underpinning
Polyurethane concrete leveling is designed for unattached or floating flatwork slabs—such as driveways, sidewalks, patios, and interior basement floors. Because the polymer weighs roughly 4 lbs per cubic foot (compared to 100+ lbs per cubic foot for cementitious mudjacking slurry), it fills washed-out voids without adding heavy weight that would cause soft sandy loam to sink again.
However, if a load-bearing perimeter wall, brick chimney, or structural footing is settling, foam injection is not a substitute for steel piers. Compare all of our foundation and waterproofing services in Michiana, review structural underpinning on our foundation repair in South Bend page, or book a foundation inspection in South Bend so a licensed contractor can inspect your property.
Concrete Leveling FAQs
How is polyurethane foam slabjacking different from traditional mudjacking?
Polyurethane foam uses smaller penny-sized injection holes, weighs only about 4 pounds per cubic foot so it doesn't overburden soft soil, is waterproof, and cures ready for vehicle traffic in 15 to 30 minutes.
When does a sinking slab need foundation piers instead of slabjacking?
Slabjacking lifts floating concrete panels like driveways, sidewalks, patios, and interior basement floors. If a perimeter load-bearing wall or structural footing is sinking, steel push piers or helical piers are required.
