Drive-Through Lane Repair

Restaurant Drive Through Lane Lifting, Jacksonville, North Carolina

Problem:

Concrete slabs in drive through lane at fast food restaurant in Jacksonville, North Carolina settled. Settlement between slabs of up to 2 inches created a tripping hazard for anyone walking on the slabs, and indicated a problem with the soil below the slabs. Deflection of the joint also could cause potential future damage to embedded sensor wires.

Constraints:

Due to high traffic volume, work had to be performed outside of normal operating hours, and then be immediately available for use afterwards.

Solution:

High density polyurethane grouting to raise the settled slabs back to their original levels. The joints with differential settlement were saw cut a week before the work was completed to ensure that lifting could be completed quickly and without slabs binding.

Results:

Single CJGeo polyurethane grouting crew raise the drive through lane slabs in a few hours. The restaurant was able to utilize the drive through lanes the next morning when they opened, without any restrictions.
