Waterjetting. Surface Preparation, Hydrocutting, Hydro demolition, unclogging and industrial cleaning

  • Waterjetting for surface maintenance.
  • It is the most sophisticated technique in the world to replace the unhealthy sandblasting. Ultra high pressure water (UAP) at 3,100 bar is used, which leaves the surfaces free of paint and invisible contaminants, ready to apply the coating according to each situation.
  • The performance (speed) of the lances is similar to that of the sandblasting.
  • We also have an automated robot (it is operated with a joystick), which has a performance similar to that of 6 simultaneous sandblasting peaks.
  • This robot sticks to surfaces by suction and collects dust, paint and water, leaving it in a bag / filter, ready for final disposal.

Among the advantages of waterjetting for surface preparation, unlike traditional methods, are the following:

  • It is considered cold work, it does not generate sparks such as sandblasting, hydro-sandblasting or shot blasting.
  • Does not generate pollution.
  • The removed paint is the only waste.
  • Surfaces are cleaner, with no visible contaminants.
  • Does not encapsulate contaminants or paint like shot blasting.
  • Complies with SSPC-NACE VIS 5 regulations.
  • Insurance for operators.
  • Selective paint layers, or all, can be removed in one step.
  • It does not require previous or subsequent surface washing, as occurs with abrasives.
  • Does not require cleaning the work area.
  • Does not require masking instruments or mechanical equipment.
  • Even removes elastomeric coatings.
  • Avoid the need to use assisted air.
  • Respect environmental regulations.

  • By using self-propelled probes with high and ultra high pressure water.
  • By shot blasting and sandblasting equipment.
  • Using probes.
  • We have high-end borescopes for the control before and after work.

The advantages of the robot over conventional sandblasting are:

performance up to 60 m2 / hour 8 m2 / hour per nozzle
Pollution None High. It causes lung cancer to 35% of the workers involved and in the immediate vicinity. A disease known as silicosis.
Type of job Cold work Hot work both sandblasting and hydroblasting
Waste The only residue is the removed paint. It is contained in a container. Approximately 0.2 kg / m2. Waste Produces 40 kg / m2 of contaminated sand. The robot equivalent would produce 2,800 kg of contaminated sand per hour of work.
Dust Zero It must be removed to prevent the coating from failing.
Non-visible contaminants Eliminates 100% of non-visible contaminants. It is necessary to perform a hydro-wash prior to sandblasting and another subsequent hydro-wash, and still it is not possible to eliminate 100% of the contaminants.
Guarantee Paint manufacturers provide extended warranties when working with this method. Limited warranties. It is necessary to carry out a bresle test to ensure its correct cleaning.
Interferences Does not generate interference with other items. It is possible to paint and carry out other tasks simultaneously with the treatment. No tasks can be performed in the immediate vicinity.
Time Being automatic it is constant and reduces project times by more than 60%. It depends on the weather and the mood of the operators.
Lead paints They can be removed without having contact with the staff. It is impossible to eliminate without generating dust on the surface and affecting the health of workers.
Elastomeric paints / fiberglass Easily remove them. It is extremely slow and many times it is necessary to macerate before sandblasting to remove it manually.
Security As the robot does the work, it is an extremely safe task. Highly risky task. Personnel at height with pollution present, assisted air masks and hoses under pressure in their hands.
Technology Last generation. Used and recommended by the most advanced oil companies and in the main navies in the world, from the U.S. Navy to the Brazilian, Chilean, Uruguayan and Argentine navies. Obsolete, banned in all developed countries and also in Brazil, Chile and Uruguay because it is considered extremely harmful to health.
