Hydro Demolition and Hydro Cutting

Applications

• Selective cleaning of concrete structures (up to 2,500 kg/cm ²).
• Demolition of concrete structures and large areas up to H-1,000.
• Elimination of rust from steel structures.
• Preparation of construction joints and expansion joints.
• Gallery perforation.
• Hydroblasting.
• Cleaning of slopes.
• Preparation of construction joints.

By type of material it can be applied to:

• Reinforced concrete.
• Mass concrete.
• Metallic surfaces.
• Concrete paving.

Technical Equipment

• Works with guns and nozzles

  150 HP equipment for working pressures up to 2000 bar and a flow of 20 l/min.
• 480 HP equipment for working pressures up to 1000 bar and a flow of 200 l/min.
• Robot arm on crawler.
• Hydroblasting accesories for eliminating paint from concrete paving and for cleaning metallic surfaces.
• Guns and nozzles for use in places difficult to access.
• Special hoses.

Advantages

• Selective demolition of concrete

  Does not affect the metallic strcuture.
• Does not produce vibrations to the structure.
• Does not damage healthy concrete.
• Allows for selective demolition.
• Does not generate sparks or dust.
• The clean surface is rough which is ideal to apply new concrete.
