Blast Day
The town of Pembroke awoke on blast day to the same windswept rainy conditions as any other day, and throughout the morning, townspeople and plant employees gradually gathered in an open field about one mile from the blast zone. At precisely 9:00am, the 350-foot stack was detonated.

The structure fell exactly as planned, dropping in a straight line between the tank farm and generating station. As it impacted with the ground, debris shot towards the stacked containers, only to bounce back harmlessly into the drop zone. Phase-1 of the project had gone well.
Then came the moment of truth. At 9:02am, all in attendance held their breath as the 725-foot concrete stack was detonated.

As the dust gracefully swept away to the east, a narrow 200-foot-long debris pile offered convincing testament to the project's overwhelming success. An independent analysis of adjacent exposures performed by Protec Documentation Services found that all critical structures and environmental concerns remained completely unharmed.

As far as visual spectacles go, the industry had seen far more dynamic-looking blasts. However in an age when the development of truly innovative methods for demolishing structures are few and far between, the blast team at Controlled Demolition Group had successfully 'pushed the envelope' in creating a proven method for stack demolition in tight quarters.
