How Implosion Works

Although implosions only make up less than 1% of all demolition work, it’s still worth talking about. Primarily because implosions are just plain cool and fun to watch. While these building implosions are exciting, they’re also really dangerous and need to be handled with a lot of preparation.How Implosion WorksImplosion vs ExplosionOne of the biggest, and most common, misconceptions about demolition is that people use implosion and explosion interchangeably. The key difference is that explosions use force and energy to send material out, while the goal of an implosion is to get the structure to collapse in on itself. The reasons implosion is favored over explosion are:
  • Implosions are safer because there’s less risk of flying debris
  • An explosion could seriously damage surrounding buildings and structures
  • Clean up goes faster with implosions because the radius of debris is much smaller
How it WorksThe first step when designing an implosion is to divide the structure into several vertical columns. Next, the blasters (highly trained implosion experts) will drill holes in the load-bearing supports of each column and fill the holes with dynamite. To contain debris, each support is wrapped in a special combination of fencing and fabric.All the dynamite is controlled by blasting caps, which are connected to a single detonator via miles and miles of detonator cable. When everything is ready, the detonator will start a carefully coordinated series of dynamite explosions, which will cause the building to fall in on itself. When done correctly the implosion will have a liquid collapse, which refers to the smooth and progressive look of the implosion.Implosions should always be handled with extreme care and precision. Not every demolition is qualified to handle an operation of this scale. A DT Specialized, our team has handled hundreds of implosions and we know what it takes to do it right and do it safe.
