Marine Growth Structures – Cavitation & Pressure Clean

We can remove “overgrown” marine growth (especially hard shells) and dirt, from:

  • Hull vessels running gear.
  • Mooring systems.
  • Underwater wharves strainers intakes and pipes for refrigeration, aircon, pumps, etc.
  • Pools
  • Shark nets
  • Pit wells and pumps for artificial lakes.

Get a professional clean of your jetty, pontoon or boat ramp this spring… so you can have it looking great for summer.


The system is based on the principles of cavitation when collapsing bubbles generated by a proprietary system create a vacuum that quickly and safely removes fouling materials.

The advantages of this system over conventional high pressure blasting grit blasters barnacle blasters or brush cleaning are many:

  • The systems are safe to use. The water stream will not inflict damage to a diver who may come in contact accidentally.
  • Clean steel, concrete, wood, rubber, fiberglass or fabric, without damaging existing surfaces or surface coatings.
  • All types of marine growth from seaweed to hard well-attached barnacles are easily removed with only one pass saving operators time and money.
  • Surfaces with paint varnish or anti-fouling coatings are not disturbed when cleaned and heavy metals or other contaminants are not released into the water.
  • The systems use either fresh water or seawater.
  • The cavitation system leaves a smooth surface that retards biological growth and decreases cleaning frequency.


The high-pressure water cleaning method relies on its own impact force to remove biofouling on the hull.

We can water blast underwater and the swim areas making it as safe as possible for your family to enjoy!

  • Swimming enclosure and rocky areas clean
  • Private jetty cleaning
  • Barnacles & Oysters removal
  • Pontoon cleaning
  • Boat ramp high-pressure cleaning
  • Pylons & Wharf high-pressure cleaning
  • Slipway high-pressure cleaning
