Office Floor Lifting

Office Floor Polyurethane Grouting, Baltimore, Maryland

Problem:

Slab floors inside of two buildings at an office park settled, creating trip hazards. One building had approximately 100 LF of 1/2″ differential settlement at a joint running down the center of a hallway. The second building had approximately 60 LF of 3/8″ differential settlement in a cubicle area.

Constraints:

Work had to be completed without disruption of operations, and with minimal disturbance to the floor covering (glued-down carpet).

Solution:

Polyurethane grouting to raise and support the interior floor slabs.

Results:

NCFI high density polyurethane was injected through holed drilled in the floor to raise the slabs back to their original positions. The work in both buildings was completed in approximately 3 hours, on a weekend. To access the slab floor, small L-shaped cuts were made in the carpet. After injection was completed, the carpet was glued back down.
