  • Thermal expansion: Concrete expands during hot weather conditions and contracts in cold weather. This fluctuation can cause cracks in the sidewalk.
  • Tree or shrub roots: Maturing trees or shrubs can grow under the sidewalk, causing damage. To prevent this problem, trees should not be planted too close to sidewalks.

  • Polyurethane foam is injected into the void. The foam expands and fills in the void. This helps lift the sidewalk back to its original level without replacing it.
  • After the injection process, all holes are filled in and the equipment is removed.
  • The polyurethane foam hardens within 15 minutes, allowing the sidewalk to be used quickly.

We use polyurethane foam because it offers benefits such as:

  • Economical: Polyjacking is 75% cheaper than removing damaged concrete.
  • Versatility: It can be applied to apartment buildings, shopping malls, sports arenas, libraries, concert halls, and other locations.
  • Accuracy: Polyurethane foam precisely lifts the concrete within 10/1000th of an inch.
  • Moisture Barrier: Polyurethane seals concrete cracks and joints to stop water intrusion.
  • Conformability: The foam expands 20 times its liquid volume and moves laterally under the concrete surface. It contours to the size and shape of the voids providing 100% coverage.
  • Light-weight: Polyurethane only adds 3-5 pounds per cubic foot to the sub-base to prevent stress to the soil.
  • Structural support: Because our experts drill small holes into the affected area, this helps support and maintain the structure of the concrete.
