Applications in Technical Projects

• Hydrodemolition
• Hydrocutting
• Sand blasting – paintings
• Refractory/Passive fire protection coatings
• Hydro blasting – Maintenance of marble surfaces
• Dry ice blasting:

• Surface cleanings (stone, wood, marble)
• GRAFFITI removal
• Rehabilitation from natural disasters

Hydrodemolition is the term used for the cutting and removal technique of concrete from built surfaces using a (High Pressure Water Jet.
Hydrodemolition is now recognized by the Civil Engineers to be the safest, most efficient and vibrations-free method for the removal of concrete. The remaining structure suffers no crack, the reinforcement steel stays intact, so, the initial integrity is maintained.

Technical advantages

• • No micro-cracks within the structure
  • No damage to the reinforcing steel and no relaxation of the structure
  • The reinforcing steel is cleaned by the application of high pressure water, thus, creating proper surface conditions so that new concrete can bond to the existing one.
  • Hydrodemolition enables the precise and selective demolition, ensuring the removal of just the concrete that has gone bad, leaving the good material intact.

Environmental advantages

• • Hydrodemolition minimizes dust pollution
  • No noise from the echo caused by demolition hammers.
