Elliot Lake inquest

The man responsible for waterproofing the mall that collapsed in Elliot Lake says their inability to stop severe leaking was “disheartening.”

Dave Monroe says he had reservations about the mall’s design but that his company, Harry S. Peterson, wanted the job. He says the problem was the use of precast hollow-core slabs loosely tied together for the roof deck instead of using one large concrete pad. Monroe says the slabs moved in ways they had not expected. The roof mall collapsed last June, killing two women.
