After almost a month of rumour and speculation regarding a failed implosion in Canada, we have just been alerted to this footage which shows the Norsk Hydro plant in Becancour failing to succumb to explosive demolition.

According to the video, the contract was overseen by EDS, although we understand that the explosive works may have been subcontracted to a third-party (if anyone can confirm this we’d love to hear from you).

Last week, we brought you footage of Asarco Demolition’s dual implosion of a pair of smokestacks in Montana. But we’ve just uncovered this new high definition footage of the blast. If only all demolition video looked as good as this (and be sure to hit the Full Screen option – the four little arrows in the bottom right-hand corner of the screen):

MGL Demolition this weekend completed the demolition of Fulbeck House and Glentworth House in Middlesbrough’s Netherfields area. These were built in 1968, and each 16-storey block comprised 90 flats.

A lottery to press “the button” raised money for Normanby’s Zoe’s Place and was won by schoolgirl Joanna Gray.

According to the English-language voice over, the implosion of this incomplete and abandoned high-rise structure in the Chinese city of Zhongshan took place in a residential area. Which calls into question the huge amount of debris discharged by the blast.
