Sinking or uneven concrete is a common problem that happens over time due to settling. In order to fix uneven concrete, we use a polyurethane foam to lift the concrete back to its original position. Similar to spray foam, this foam is easily and quickly applied for lasting results.
The foam used for concrete leveling is a two-part polyurethane foam engineered to withstand pressure and is water resistant. To level concrete, we first drill small holes in the surface of the concrete. Then, we inject high-density foam through the concrete. As with spray foam, PolyPier foam expands as it is applied. While the foam is being injected, it moves beneath the concrete, filling any gaps and voids along the way. As we add more foam, the gaps fill and the concrete raises as a result.
We can use this process for leveling and raising concrete for the following applications:
When comparing polyjacking to the traditional method of mudjacking, polyjacking is quicker, is less invasive, and delivers permanent results. Mudjacking uses a slurry mix of natural elements including mud, sand, cement, and crushed limestone. Because these items are a mixture of natural elements, they can be somewhat chunky, therefore it may not completely fill gaps and voids, whereas polyurethane foam can. Since mudjacking a slurry mixture, it needs time to cure. Once the mixture dries, it adds more weight to already compromised soil below, allowing for further settling to occur. Since polyjacking uses polyurethane foam, it is lightweight, and able to fill even the smallest of crevices, but packs a punch with strength and stability that provides a permanent result.
