Hydrodemolition, or hydro demolition, is a concrete removal technology that uses high-pressure water to remove damaged concrete, asphalt and/or mortar. This method offers several advantages over traditional methods. Traditional methods used in concrete demolition often have the disadvantage of damaging the reinforcement and allowing cracks to appear in the concrete. Thus, the healthy parts of the concrete also get damaged. In addition, the vibrations cause the reinforcement and concrete at the site to loosen.


  • Demolition can be carried out without damaging the reinforcement / rebar
  • It creates an excellent bonding surface for new concrete
  • It does not cause micro-cracks
  • Work can be done dust-free
  • Is suitable for selective and non-selective removal
  • Selective removal is the preferred method when only the affected concrete needs to be removed
  • Non-selective removal (also known as “hydromilling”) is the preferred method when concrete must be removed to a predetermined depth, regardless of the quality of the concrete
