In the earlier posts in this section I have concentrated more on cutting the profiles of a hole, and the different ways in which this can be done efficiently. However there are many cases where the hole has to travel into the work piece to a depth greater than can be easily achieved without the […]

The most popular applications of high-pressure water on concrete deal with the removal of dirt and undesired coatings from the surface, or the removal of layers of the immediate surface for repair, hydro-demolition. There is, however, also an application where the concrete has to be removed in its entirety. Most often, this is done with […]

In this short section of the series I have been discussing some of the issues that relate to cutting through concrete. In today’s piece the discussion will continue, focusing on the angles that the jets are set at, when making repeated passes over an area to deepen the cut. The basic premise of the discussion […]

The control of cut depth is one of the more difficult aspects of using high pressure waterjets in places where the aim is not to cut all the way through a part. The ability of an abrasive jet to continue cutting beyond the expected target depth can first be evident to an operator when they […]

There are a number of differences that take place when high-pressure waterjet operators change from a lower pressure, higher volume flow rate to one where the jets are operated at a higher pressure, with a smaller jet size. One way of illustrating the difference is in the way that the jet will interact with concrete, […]
