9″ Floor Lift

Boston, MA


6,000 square feet of slab floor in a flex space building in Boston, Massachusetts settled up to 9 inches. The tenant of a warehouse space vacated at renewal due to challenges that the settlement caused for their operations. The tenant of the office portion threatened to not renew due to the settlement.


The building owner wanted to improve the function of the space by correcting the settlement. To avoid further upsetting the office tenant, repairs had to be quiet, dust free, not require moving any of their furnishings, and ensure long term stability.


CJGeo proposed plural component polyurethane grouting to the owner. Plural component polyurethane grouting is exceptionally clean, isn’t dependent on third party grout deliveries, and allows immediately return to service.

A single three person CJGeo polyurethane grouting crew corrected all of the settlement in a single shift using CJGrout 28FDL. The vacant warehouse portion of the building was lifted during the day. Once the adjacent office closed for the day, the CJGeo crew lifted the office space overnight.
