When this service makes sense
Polyjacking is a common name for lifting settled concrete with expanding polyurethane foam. It is often selected for driveways, walkways, patios and pool decks. The first step is determining whether the slab is still strong enough to preserve and whether the movement is primarily settlement rather than upward heave.
What affects price?
Contractors look at the number and size of slabs, depth of the void beneath them, amount of elevation change, access for equipment, material choice, surface condition and minimum service charges. That is why two projects with the same visible square footage can price very differently.

Common questions
Is polyjacking the same as PolyLevel?
Polyjacking is a generic process. PolyLevel® is a branded polyurethane concrete-lifting system offered by authorized contractors.
What size holes does polyjacking use?
Hole size depends on the equipment and system, but polyurethane injection holes are generally smaller than traditional mudjacking holes.
How long does polyjacking last?
Longevity depends heavily on whether the original cause of settlement—such as erosion, poor compaction or drainage—has been corrected or stabilized.
