Combining precision and low rate, the water becomes a working tool which have a lot of functions. By using pressurized water, different types of work can be carried out as a preliminary o supplementary task to other maintenance and repair.

The service of hydrodemolition is suitable to make cuts in dangerous environments with fire or explosion hazard like: hydrocarbon tanks and tubers, industry off shore oil and gas facilities, nuclear industry, vessels, etc.

Thanks to the pressurized water, the necessary concrete part can be removed, rescuing metal elements embedded in it or generating necessary overlap lengths in the armor, leaving them clean and intact and, the most importantly, without affecting the concrete-bar contact, not deteriorating the rest of concrete.

On the other hand, the hydrodemolition doesn’t generate vibrations or damage in the periphery. Therefore, doesn’t generate problems in the future.

Also, using the appropriate pressure and flow parameters, we can overcome the internal resistance to the traction of the concrete causing superficial micro bursts that allow us its controlled extraction.

In all this each cases, it its necessary acting in the ground, for example, to remove an oxide layer or a deteriorated coating it is advisable to use high pressure water to clean or strip the required thickness.

The pressure water, applicate correctly, allow the surface to be ready for a new coating, or simply to recover the original image.

These techniques also are called “cold cutting”

High pressure water ejection has characteristics that can be used for applications other than hydrodemolition. One of these are high speeds achieved by ejected water >for 1.380 bar (20.000 PSI) pressure, we get a surgically fine jet 1 cm. and concentrated.

In this case, the abrasive jet generated has the following properties.

Is a cold cutting. Free of powder. Doesn’t significantly increase the temperature. Doesn’t make heat deformations. Is a damp cut, sparks are suffocated. Doesn’t generate vibrations in the structure. Is dirigible and precise. Indicated in dangerous atmospheres.

In many applications of preparing and reparation for the protection to the concrete is precise. As a preliminary step, the intervention of pressurized water techniques.

Thanks for this techniques, it can remove it, in a selective and controlled form, leaving the deteriorate concrete, leaving the armor completely clean (even for behind the armor bar, cleaning this one for pre-existing correction) and ready for later operations.
