Lifting and Leveling Sidewalks

sidewalk cracks polyjacking leveling and lifting Kansas City and St. Louis MOSidewalk cracks may seem like a minor problem, but they can be a serious safety concern. Not only are they unattractive, they can depreciate the value of your home. In addition, they create tripping hazards for pedestrians and your family members resulting in serious injury. Fortunately, this problem can be easily repaired.

At Polyjacking.com, we offer sidewalk repair to lift and support settled concrete back to its original position by using polyurethane foam injection. Ground penetrating radar is used for void detection.

Several factors make sunken concrete get worse over time such as:

  • Thermal Expansion: Concrete expands during hot weather conditions, and contracts in cold weather. These inconsistent weather patterns create cracks in the sidewalk. Sidewalks can also be affected by freeze and thaw winter cycles.
  • Settlement: Improperly compacted soil under the sidewalk can create settlement over time. Soil erosion, due to poor drainage or heavy rainfall, can cause the concrete to crack or buckle.
  • Tree Roots: Maturing trees can grow under the sidewalk, causing the concrete to disintegrate. This creates openings and gaps that allow other plants to grow in the existing cracks. To prevent this problem, trees should not be planted too close to sidewalks.
  • Heavy Traffic: Heavy vehicles weakens the sidewalk and creates cracks on the surface. To prevent this type of cracking from occurring, homeowners should not allow heavy vehicles on their sidewalks.

Polyjacking Solutions for Your Sidewalks

Polyjacking is a process that uses high-density polyurethane foam into the affected area. With the right poly equipment and trucks, this is a relatively simple process that is faster than other sidewalk leveling methods.

  • A 5/8" hole is drilled into the affected area.
  • Polyurethane foam is injected into the void. The foam expands and fills in the void. This helps lift the sidewalk back to its original without replacing it.
  • After the injection process, all holes are filled in and the equipment is removed.
  • The polyurethane foam hardens within minutes, allowing the sidewalk to be used immediately.

We use polyurethane foam because it offers unlimited benefits such as:

  • Versatility: It can be applied to apartment buildings, shopping malls, sports arenas, libraries, concert halls and other locations.
  • Economical: Polyurethane foam is 75% cheaper than other concrete leveling methods.
  • 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.
  • 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.
