Concrete Leveling & Trip Hazard Correction for Pedestrian Areas


Commercial sidewalks are exposed to constant foot traffic, weather, and soil movement. Over time, voids can develop beneath slabs, causing settlement, cracking, and abrupt elevation changes that create safety hazards and accessibility concerns.

PolyPier® systems are used to lift, level, and stabilize settled sidewalk concrete by injecting expanding polyurethane material beneath the slab. The material fills underlying voids, improves soil support, and raises panels toward their original elevation without removal or replacement.

When properly installed, concrete leveling restores safe walking surfaces, supports accessibility requirements, and helps extend the service life of existing sidewalks.

  • Eliminates trip hazards and uneven transitions
  • Improves pedestrian safety and accessibility
  • Helps address liability concerns
  • Minimizes disruption in active areas
  • Preserves existing concrete while stabilizing soils

Polyurethane leveling offers performance advantages compared to traditional slurry methods.

  • Lightweight material that does not overstress weak soils
  • Small injection points for minimal surface impact
  • Controlled lift for precise slab alignment
  • Closed-cell material resistant to moisture exposure
  • Long-term support that does not erode or wash out

These characteristics make polyurethane systems well suited for pedestrian environments where safety and precision are critical.
