FoamJack®
FoamJack® is an expanding rigid polyurethane foam engineered for lifting, leveling, and stabilizing concrete in residential and commercial applications. Designed for injection beneath concrete slabs, it fills voids, compresses underlying soil, and gently raises surfaces back to their original position without the need for excavation or replacement.
Curing in minutes, FoamJack® provides a fast, clean, and permanent solution for uneven or sunken concrete. Its lightweight structure and expanding properties allow it to penetrate loose soil, restore stability, and deliver long-term performance with minimal disruption.
Engineered for efficiency and precision, FoamJack® requires small injection holes and offers easy handling, making it an ideal alternative to traditional mudjacking methods while delivering more durable and consistent results.
