Concrete slab lifting is a process that involves resin injection underneath sunken or uneven concrete slabs to lift them back into place. This material, usually a polyurethane foam that becomes solid, is pumped through small holes drilled in the slab. Once the material is in place, it hardens and stabilizes the slab, restoring it to its original position.
Why Polyurethane Foam is the Best Concrete Lifting Option
Perhaps the most well-known concrete leveling option is mudjacking. However, there is a reason that polyurethane foam concrete leveling, also known as poly jacking, is becoming the go-to option.
- Polyjacking is less invasive than mudjacking because the holes needed are much smaller. Polyjacking only requires them to be the size of a small coin. That causes less stress on an already cracked slab, and the hole filling is less noticeable after the lifting is done.
- It is very precise. We can level the driveway within a fraction of an inch while compressing the soil around it.
- Unlike the slurry in mudjacking, the polyurethane foam, once it hardens underground, won’t erode. It is impervious to water or chemicals that are found underground, so polyjacking is a solution that will last the life of the driveway slab.
