CaviDyneLLC® employs a revolutionary technology known as Ultra-Cavitation for underwater cleaning using much lower pressures than conventional equipment. These systems are significantly more effective, efficient, and ergonomic than the traditional ones such as pressure-washers/water-blasters, or grit blasters, and they eliminate the dangers associated with the use of high-pressure cleaning equipment. CaviBlaster® systems remove marine growth in significantly less time and with better results than traditional methods - while costing less to operate. The compact CaviBlaster® units clean steel, concrete, wood, rubber, fiberglass or fabric, without damaging existing surfaces or surface coatings. The more powerful CaviBlaster® models will quickly clean surfaces to bare metal, stripping away heavy fouling and oxidation. Our biggest CaviBlaster® is known as the ConcreteBlaster®, and is powerful enough to crush concrete. Our Technology is powerful enough to clean any density surface; while not inflicting damage on painted ones. Additionally, our studies have shown that the force exerted on a diver's arm by the instrument when cleaning is comparable to that of holding a cup of coffee.
