Manchester’s Fight Against Sinkholes Calls For Pricks

Not since Manchester dusted itself down after hosting the 2008 Europa League Final has there been such an uneasy atmosphere in the city. Fear is hounding residents, blanketing its buildings and delaying the new Metrolink. This fear, however, isn’t arriving on coaches in the form of pissed Scots. This fear is underground, unseen by the human eye until it does the damage.


In August this year the Mancunian Way was brought to a close twice when sinkholes appeared. September saw the B532 in Salford closed when another was discovered and just last week Great Bridgewater Street fell victim.

“The city will not disappear,” said city Mayor Wexford Crestfuck. Keen to ease minds, he added: “Planning has already started for the Christmas Markets. We’d hardly do that if we thought Manchester would collapse around us.”

The Council’s Highways Infrastructure and Transport (HIT) spokeswoman Sheila Scrumpoke, addressed 90% of calls the HIT sinkhole hotline had received: “Coronation Street is not in danger. We expected this problem when the new set was built. Not only are the famous cobbles sinkhole proof, they’re also earthquake and IRA proof.”

“Coronation Street is not in danger.”

What HIT has done is to seek advice from across the Atlantic, specifically Tampa, Florida; the home of Dr Bud Gratestreaker. Both he and his team flew into Manchester earlier this week and began their investigations. They have been at the forefront of sinkhole activity for fifteen years. The doctor himself has a personal connection since his grandmother was swallowed by one in 2003.
“It creates a sinkhole when the air that has been supporting the ground above expels,” he said. “It’s called geoflatulence. This causes whatever sits above; in Manchester’s case seems to be only roads, to fall in on its self creating the hole.”

Using geotechnical engineering machinery throughout the city’s roads, Dr Gratestreaker’s team have scanned and identified certain core points they feel geoflatulence is possible and have been swift to act.
“We use a process called Pricking,” he explained. “We insert a steel rod into the identified area which allows the air to escape. Another steel rod pumps a solidifying solution, like expanding foam, into the void and fills it.”
When pressed about where these ‘identified areas’ were, Dr Gratestreaker said: “Owing to health and safety and so we don’t scare away potential investors, we cannot divulge exact locations….but I’d avoid Deansgate next week.”
