Concrete Lifting with Polyurethane Foam in Lenox, MA
The concrete had noticeably settled at this property in Massachusetts
The concrete was quickly lifted through the slabjacking process
The Challenge
The concrete floor at this Massachusetts property had noticeably settled over two inches due to a winter water line break, which eroded the soil beneath the slab. The building had been vacant at the time, so the leak went undiscovered for an extended period, allowing the floor slab to continue settling.
Project Considerations
Project engineers initially recommended a traditional rip and replace approach, which would have involved jackhammering the slab, replacing the subgrade soil, and installing a new structural slab. This method would have been time-consuming, costly, and highly disruptive.
The client sought a solution that could restore the slab quickly, cost effectively, and avoid major construction disruptions.
Our Solution
Engineered Foundation Technologies used polyurethane foam injections to slabjack the concrete floor. The process involved drilling small holes in the affected slab, injecting the expanding polyurethane foam into the void beneath, and lifting the slab back to its original level.
This approach effectively stabilized the slab while avoiding the extensive labor and costs associated with a full replacement.
Results & Benefits
The slab was restored in a single day, providing a cost-effective and minimally disruptive solution. The client was able to obtain their building permit and proceed with further renovations without delays.
