TL;DR
Polyjacking is the lifting of settled concrete slabs by injecting expanding polyurethane foam through dime-sized holes drilled in the surface. The two-part foam expands within seconds, compacting weak soil and raising the slab with fine control; it cures in about 15 minutes, weighs roughly 2 to 4 pounds per cubic foot, and does not wash out like mudjacking slurry.
What it means
Polyjacking is the lifting of settled concrete slabs by injecting expanding polyurethane foam through dime-sized holes drilled in the surface. The two-part foam expands within seconds, compacting weak soil and raising the slab with fine control; it cures in about 15 minutes, weighs roughly 2 to 4 pounds per cubic foot, and does not wash out like mudjacking slurry. Crews apply it to driveways, garage floors, sidewalks, and pool decks at a premium over cement-based lifting.
