Underwater Blasting

Pirate vs Explosives Animation - 00:45 sec (2.1 mb)

As with other blasting applications, the use of explosives in underwater environments can provide quick and cheaper alternatives to breaking hard bedrock or underwater structures than attempting to do this solely with heavy machinery, rock hammers, excavators or dredgers.

It is possible to utilise small explosives charges on millisecond delay intervals to simply pre-condition or crack rock in-situ to speed up and facilitate the use of more conventional dredging and excavating tools.

In many cases, blasting will reduce or eliminate the need for divers working with powerful equipment underwater.
