Polyjacking is a much newer method and more state of the art version of mudjacking for concrete raising except instead of a cement slurry being forced in and lifting the slab, an expanding polyurethane foam is used which is lighter and more effective than the cement slurry. The holes drilled in the slab for polyjacking are much smaller than those used for mudjacking which will make them ultimately less noticeable.
Using the polyurethane foam instead of the conventional cement slurry allows us to lift larger slabs in less time because the foam expands on its own. This means we do not have to rely on the pressure of the slurry to do the heavy lifting. The foam also has a much shorter cure time which means you are able to put weight on the slab in less time and get back to your life much faster.
The polyjacking process is relatively simple and once we are at the location, we can begin the process to raise your sinking concrete fairly quickly. The polyurethane injection process is outlined below.
Evaluate sinking slab for best areas to begin lifting process.
Drill small holes into the slab and attach nozzles to begin injection.
Inject expanding polyurethane foam into holes.
As the foam expands and fills the void, the slab will begin to raise.
Continue until desired height and level are achieved.
Remove nozzles and patch holes.
Once foam is cured, slab is stable and repaired.
If you have any of these problems, they can all be repaired using our polyjacking concrete lifting method.
