Concrete removal and resurfacing made simple.

Conventional methods for repairing concrete bridge decks, wharf piers, multi-tiered car park decks etc, have involved removal of the deteriorated concrete below the reinforcing bar by jackhammers and other percussion tools – these methods are costly, time consuming and offer no assurance of complete removal of deteriorated concrete.

Now high pressure water is being used successfully in the removal of deteriorated concrete and asphalt from bridge decks, highways, substructures and parking lots – known as Hydrodemolition.

Hydroscarification is the ultimate method to prepare concrete for resurfacing where chemical attack has caused deterioration of the concrete surface. Ultra high pressure water at comparatively low flow rates is directed at the surface via a rapidly rotating nozzle assembly.

  • No dust
  • Noise greatly reduced
  • Superior substrate bonding surface
  • Does not create additional structural damage
  • Selectively removes inferior concrete
  • Re-bar is cleaned, descaled and undamaged
  • Is faster than mechanical removal methods
  • Minimises removal of sound concrete
  • Washes away entrained chlorides and salts.

  • Removes cancerous and spalling concrete rapidly, leaving a clean profile exposed that is ideal for bonding of newly applied concrete and flexible coatings.
  • The low water flow ensures the depth of removal is able to be accurately controlled, resulting in savings of new materials to be applied.
  • Applications include renovation of the interior walls of water and sewer tunnels, remediation of concrete building facades, remediation of the walls of concrete tanks and removal of coatings from swimming pools.
  • Reinforcing bars can be exposed, cleaned and descaled without the mechanical damage caused by other methods, such as grinding, jackhammering or chipping.
