Even roughening of surfaces using a high-pressure water jet

The roughening of fine and coarse surfaces is necessary for maintenance and renovation in many applications. For instance, some well-known examples for such overstressed surfaces in need of regular profiling are often landing strips, racetracks, or parking lots. In conclusion, all of them lose static friction over time. Unquestionably, all of them are required to provide grip to be usable. If the surface doesn’t deliver the required grip, the surfaces can either be roughened up again or for the first time by using a high-pressure water jet.

What are the advantages of high-pressure water jet compared to sandblasting?

In the past, sandblasting was often used to roughen surfaces. However, in contrast to high-pressure water blasting, the sandblasting process has a number of disadvantages. As a matter of fact, sandblasting is not only time-consuming and expensive, but also harmful to the environment. Finally, sandblasting produces a lot of dust and dirt. Basically, this dust and dirt, in turn, can spread to adjacent surfaces and into the air.

Surface roughening applications using high-pressure water jets



Especially by using a high-pressure water jet, it is possible to profile the surface quickly, efficiently and in an environmentally friendly manner. However, the water jet is directed at the surface to be treated with a pressure of up to 3,000 bar. As a result, it is removed and roughened evenly. In conclusion, compared to the sandblasting process, the high-pressure water jet is significantly more precise. In addition, there is no risk of damaging the material or causing unwanted changes to the surface.

Is roughening with water much more environmentally friendly than conventional methods?

To sum up, the usage of water jets for surface roughening isn’t only very suitable for the job because it is fast and efficient, but also comes with great advantages for the protection of the environment. Because of the high pressures, the water can do without additives like sand or artificial granulates which could then potentially pollute the direct environment.

As a result, the high-pressure water jet method protects the environment much more than other conventional processing methods such as sandblasting. At least, when roughening with water jets, the environment is protected much more than with other, classic processing methods.

KAMAT provides everything from a single source – from the high-pressure pump to the water tool: KAMAT is a direct supplier for entire pump units even with surface cleaners designed for that purpose that can also be mounted on vehicles.

KAMAT’s all-in-one solution: efficient roughening of surfaces

All in all, the processing of surfaces using high-pressure water jets offers a fast, efficient and environmentally friendly method of increasing the static friction and safety of heavily used surfaces. KAMAT’s all-in-one solution makes this method easy and inexpensive to implement, so you too can reap the benefits of water roughening.
