What to Expect During a Polyjacking Service Appointment
May 22, 2025When you notice that your sidewalk is sloping and your driveway is sinking, or your patio is looking uneven, you’re not alone. These are common signs of concrete settling, and thankfully, there’s a fast and effective fix.
Polyjacking is a modern concrete lifting technique that raises and stabilizes sunken concrete using expanding foam. It is a cleaner and more efficient alternative to traditional mudjacking, and it’s growing in popularity across St. Louis homes and businesses.
If you’re thinking about scheduling your first polyjacking service, you might have a few questions, and that’s totally normal. In this blog, we’ll walk you through what a typical polyjacking appointment looks like from start to finish. Knowing what to expect can help ease any concerns and make the process simple.
Initial Consultation and Site Assessment
phone or through our website, we’ll work with you to schedule a convenient time for your appointment.
On the day of your assessment, one of our experienced technicians will arrive to inspect the area in person. They’ll confirm the scope of work, check the condition of the concrete, and discuss any concerns you may have. Whether it’s your garage floor, porch steps, or pool deck that needs attention, we make sure to understand your goals before the work gets started.
What happens in the Work Area?
Once the assessment is complete, it’s time to prepare the area.
We will always begin by taking safety measures to keep your home and family protected during the process. Our team will take care to protect the surrounding landscaping, walls, or nearby structures from equipment or foam exposure. If it is needed, we’ll place tarps or shields to avoid a mess and keep things tidy.
Next, we set up our equipment. This includes drills, hoses, and the polyurethane foam rig typically housed in a truck or trailer outside. The setup is efficient and contained and we always aim to keep disruption to a minimum.
Drilling and Injection Process
The process begins by drilling strategically placed holes in the concrete slab. Through these holes, we inject a specialized polyurethane foam underneath the sunken slab.
As the foam expands, it fills voids in the soil and gently lifts the slab back to its original position. The process is carefully monitored with precise leveling. We make adjustments as needed to get the best possible result.
What makes polyjacking so impressive is how quickly it works. You can actually see the concrete rise right before your eyes!
Clean-Up and Finishing Touches
Once we’ve reached the desired lift, we seal the small injection holes with a patching compound that blends in with your existing concrete. Then we clean up the worksite by removing any debris, equipment or protective coverings used.
Before we leave, we will walk you through the completed work so you can see the results for yourself and get a better understanding of the outcome. We’ll also answer any questions you may have and share simple tips to maintain the integrity of the repair.
Post-Service Recommendations
The great thing about polyjacking is that it doesn’t take a long time to set. In most cases, you can walk or drive on the surface just 30 minutes after it’s done.
We’ll also share a few easy tips to help keep it in good shape and condition, like making sure water drains away from the area, sealing any cracks, and avoiding heavy weight on it for a little while.
