The concrete lifting company was called and the work was completed in 6 hours. Using the EliteOne gun and HMI’s 501 polyurethane foam the void was filled, which stabilized the concrete slab. 501 polyurethane foam was chosen for this job because it provides a slower reaction time and further spread. Due to the distance this foam can travel, 501 is excellent for undersealing and stabilizing joints on rocking slabs from slab curl. The same dial gauge test was performed after the foam was injected, and showed no deflection. The CNC’s were re-leveled and operations continued. The only alternative would have been to tear out, and replace the entire slab. Which would have affected production greatly. By choosing to fill the void, they were able to continue production immediately following the repair.
