Bulk material blockage cleaning with Cardox

B20 Underwater Excavation

Underwater Excavation, Rockbreaking & Demolition


Force Vector is a sister company to Deca Vibrator, providing complementary products and services to our material handling solutions. 

Because the Cardox systems produce no shock wave and minimal vibration, Cardox solutions are completely safe for underwater excavation applications – even in close proximity to ships, structures, and sensitive areas. They generate no noise and no danger to marine life. Divers can even stay underwater (10 M away from tube ignition)  during tube activation.

Typical underwater applications require use of core drilling system to drill  holes for insertion of Cardox Tubes. Tubes are generally restrained in hole by use of simple 16” square ½” thick plate steel top hat configurations, placed over tubes once they are wired together,

Great for trenching, knocking down of rock outcroppings and demolitions of concrete structures. Underwater solution require a unique set of logistics! Call and speak with a Deca Vibrator Industries Inc applications specialist for more details.
