A sinkhole in Pennsylvania, which led to the tragic death of a woman last month, is currently undergoing restoration efforts involving the introduction of hundreds of cubic yards of grout to ensure site safety.

Located in the village of Marguerite, approximately 40 miles east of Pittsburgh, this operation commenced shortly after the body of 64-year-old Elizabeth Pollard was discovered on December 6, four days following her disappearance while searching for her beloved cat. The sinkhole is situated close to a restaurant approximately half a mile away from her residence.

According to local reports, more than 3,300 cubic yards of grout have already been injected into the problematic area. However, the timeline for the project’s completion remains uncertain. Work was temporarily halted due to adverse weather conditions, including snow and plunging temperatures, but authorities are optimistic about resuming efforts soon.

State environmental representatives explained that the crews are creating between 12 and 16 boreholes, strategically located throughout the site. Each borehole is being filled with a grout-like substance that will gradually expand over a 25-foot radius as it cures, thereby forming substantial pillars to support the ground above.

It has been indicated by officials that the sinkhole is believed to have originated from a small opening the size of a manhole that may have recently formed above a former coal mining area, which ceased operations nearly seven decades ago. Notably, local hunters and restaurant employees reported to police that they had not observed the sinkhole prior to Pollard’s unfortunate event.
