Polyjacking is the perfect solution for restoring sunken or uneven concrete surfaces quickly and effectively. Whether it’s your driveway, patio, or sidewalk, sinking concrete not only detracts from your property’s appearance but also creates safety hazards. With polyjacking, you can resolve these issues efficiently and restore your surfaces to their original condition without delay.

How Long Does Polyjacking Take?

Polyjacking, also known as polyurethane foam injection, is a method used to lift and level sunken concrete slabs. The duration of the polyjacking process varies depending on the project’s size and complexity. However, most residential jobs are completed within a few hours. Once the procedure is finished, the polyurethane foam cures rapidly, often allowing you to use the leveled area the same day, sometimes within just a couple of hours.

Factors Influencing the Duration of Polyjacking

Several factors can affect how long a polyjacking project takes:

  • Size of the Area: Larger surfaces require more time to treat.
  • Extent of Settlement: Significant sinking may necessitate additional foam and time.
  • Accessibility: Hard-to-reach areas might prolong the process.
  • Weather Conditions: Extreme temperatures can influence curing times.

Despite these variables, polyjacking remains one of the quickest methods for concrete repair.

The Polyjacking Process

Polyjacking involves injecting an expanding polyurethane foam beneath the sunken concrete slab to lift and stabilize it. Here’s a step-by-step overview:

1. Assessment and Preparation

A thorough inspection identifies the affected areas and the underlying causes of settlement. This evaluation helps in planning the injection points and estimating the amount of foam required.

2. Drilling Injection Holes

Small holes, typically less than an inch in diameter, are drilled into the concrete at strategic locations. These serve as entry points for the polyurethane foam.

3. Injecting Polyurethane Foam

A specialized injector pumps the polyurethane foam through the holes into the voids beneath the slab. As the foam expands, it fills the gaps and gently lifts the concrete to its original level.

4. Curing and Cleanup

The foam cures quickly, often within 15 minutes, stabilizing the slab. The injection holes are then patched, and the area is cleaned, leaving minimal visible evidence of the repair.

Advantages of Polyjacking

Polyjacking offers numerous benefits:

  • Speed: The process is swift, with minimal downtime.
  • Minimal Invasiveness: Smaller injection holes mean less disruption to the existing concrete.
  • Lightweight Material: Polyurethane foam adds less weight to the underlying soil, reducing the risk of further settlement.
  • Durability: The foam is resistant to moisture and erosion, providing a long-lasting solution.

When Can You Use the Leveled Area?

One of the significant advantages of polyjacking is the rapid curing time of the polyurethane foam. In many cases, the repaired area can be used within hours after the procedure. This quick turnaround minimizes inconvenience, allowing you to resume normal use of driveways, sidewalks, or patios the same day.
