PROBLEM…

Significant heaving from slab to slab.

Approximately 10"-12" Creating hazards for

pedestrian and wheeled traffic.

SOLUTION…

The hypothesis was that the grates were rusted and creating pressure on the slabs.

Exploratory slab removal to identify any flowing water or unknown variables under the slab.

PROCESS & RESULTS…

HSS saw cut to remove the pressure off of the slabs.

Removal of concrete surrounding the drain.

Rebuilt the drains and replaced/reset the grates.
