Concrete That Meets Code and Prevents Falls

Sidewalk Repair for uneven surfaces that create tripping hazards and liability exposure

Jacked Concrete Lifting addresses uneven sidewalk slabs across the Quad Cities by raising settled sections back to their original height, eliminating the vertical displacement that causes trips and falls. Property owners notice these height differences when one slab sits lower than the adjacent section, creating a lip that catches feet, wheelchair wheels, and stroller casters. The repair process restores flush transitions between slabs without removing and replacing the concrete, which means sidewalks remain usable within hours rather than days.


Sidewalk settlement happens when soil beneath the slab compresses unevenly, often due to water washing away supporting material or organic matter decomposing below the surface. The lifting process injects expanding material beneath the low slab, applying controlled upward pressure until the surface matches the height of surrounding sections. Onceleveled, the sidewalk presents a uniform walking surface that complies with accessibility standards and reduces the risk of injury claims.


Schedule a property evaluation to measure height differentials and determine which sections require adjustment.

What Proper Sidewalk Leveling Requires


The repair begins with drilling small access holes through the settled slab, typically no larger than a nickel, positioned to distribute lifting force evenly across the panel. During  poly foam jacking, expanding polyurethane foam is injected beneath the concrete, filling voids and raising the slab incrementally while technicians monitor height with precision instruments. This approach works for sidewalks constructed from standard concrete mix, though heavily fractured slabs may need additional stabilization or partial replacement before lifting.


After completion, you see smooth transitions at slab joints where previously there were abrupt drops, and the walking surface returns to its intended grade and slope for proper drainage. Pedestrians no longer catch their toes on raised edges, delivery personnel move carts without jarring bumps, and residents using mobility devices navigate the path without sudden elevation changes. The original concrete remains in place, retaining its cure strength and weathering characteristics rather than starting over with new material that takes weeks to reach full hardness.


Sidewalk repair does not address surface cracks unrelated to settlement, nor does it correct slabs damaged by tree roots actively pushing upward, which may require root management before lifting holds. Work typically finishes in a single visit for residential properties, though commercial sites with extensive frontage may require phased scheduling to maintain pedestrian access during business hours.

Questions Before Starting Your Project

Property owners in the Quad Cities region often ask about repair processes and outcomes before scheduling work, particularly when comparing options for managing settled concrete.

  • What causes sidewalk slabs to settle unevenly?

    Soil compaction beneath the slab occurs when water erodes supporting material, organic debris decomposes, or fill dirt consolidates over time, creating voids that allow the concrete to drop into the unsupported space below.

  • How does lifting compare to replacement in terms of project duration?

    Lifting restores sidewalk height and usability within hours, with pedestrian traffic resuming almost immediately, while replacement requires demolition, base preparation, concrete pouring, and a multi-day curing period before the surface can bear foot traffic.

  • What happens if the sidewalk settles again after repair?

    The injected material compacts the surrounding soil and fills voids, but if new erosion occurs due to unresolved drainage problems or plumbing leaks, additional settlement may happen in the same or different locations.

  • When should sidewalk repair happen rather than full replacement?

    Lifting works effectively when the concrete itself remains structurally sound despite settling, whereas slabs with extensive cracking, spalling, or reinforcement exposure often benefit more from removal and new installation.

  • How much height difference can the repair process correct?

    Technicians typically raise slabs from fractions of an inch up to several inches, depending on the thickness of the concrete and the extent of the void beneath, though extremely large voids may require base material added before lifting.
