Concrete Lifting, Void Fill And Undersealing 24-003 is a 3.0 to 4.0 lbs per ft3 density, plural component, polyurethane foam designed for concrete lifting and void filling applications. This system is hydrophobic making it ideal for applications where water may be present under or around a concrete slab. This system offers excellent compressive and tensile strength values (based on ASTM test methods) and is highly resistant to chemicals and solvents.

24-486 is a 4.0 lbs per ft3 density, plural component, polyurethane foam ideally suited for concrete lifting and void fill applications. This system has excellent compressive and tensile strengths (based on ASTM test methods) and is highly resistant to chemicals and solvents.
