What Is Polyjacking?
Polyjacking is the process of pumping an expanding polyurethane foam into the void below a sinking, settling, or cracked concrete slab in order to lift it back into place. This foam is an ideal solution because it is inorganic and will not break down over time. This will ensure that your concrete will continue to be level and will not sink back into place from the filling material breaking down.
Our team has performed concrete lifting on countless projects using this polyurethane foam and we are confident it will permanently repair your sinking, cracked, or settling concrete slab.
How does Polyjacking work?
The process of polyjacking is straightforward, simple, and very effective. The sinking concrete repair process is as follows:
- Clean the damaged concrete surface to prevent any dirt or debris getting in the way of a proper repair.
- Drill small holes in the surface of the sunken concrete.
- Polyurethane foam is steadily injected through the small holes.
- Concrete rises evenly as the foam expands in the cavity below the concrete.
- Once slab is level, we will patch all drill holes.
The advantages of polyjacking over similar methods are that it is very cost effective, quick to implement, comprehensive due to the way the foam expands completely, and the longevity of the repairs.
