Case Studies

Built in 1927, Grosse Pointe South High School is a city gem — even today. In 2016, thousands of gallons of raw sewage came up through the sewer main into the large mechanical room in the basement, threatening the beauty and safety of this historic building.

In addition to several life safety challenges in the school’s old basement, massive amounts of biohazard waste made the space unbreathable. Sharp edges, confined spaces, constantly changing floor depth, pipes jutting into the walkway, and low ductwork made the layout incredibly dangerous to navigate even in normal circumstances.

Signal assigned the school with 12 mitigation technicians. Our restoration technicians are highly trained and certified by the Division of Occupational Safety and Health (DOSH). With the risk of tearing personal protection gear, physical injury and dangerous raw sewage present everywhere, safety was one of our greatest priorities.

Our team was able to safely remediate the hazardous water and sewer damage to ensure a safe environment for facility, staff, and students for years to come.
