Polyjacking (Polyurethane Foam Concrete Lifting) in Omaha, NE

Polyjacking — also called polyurethane foam injection or foam jacking — uses a lightweight, expanding two-part foam instead of traditional slurry. The foam is injected beneath the slab, where it expands to fill voids and lift the concrete.

Contractors typically drill smaller holes than mudjacking requires (often around 5/8 inch, though this varies), inject the foam, and the slab can often be walked on again relatively quickly after treatment — actual cure and return-to-use times vary by contractor, product, and project size. The foam is generally lighter and more water-resistant than cement slurry, which some contractors point to as an advantage for certain soil or drainage conditions.

• Homeowners who want a less invasive repair with smaller holes
• Areas with drainage or moisture concerns where a water-resistant fill material may be preferred
• Projects where minimizing weight added to the sub-base matters
