surface preparation in an underpass: uniform concrete removal with the falch surface worker 250!
besw betonerhaltung südwestfalen gmbh was awarded the refurbishment contract for an underpass in korschenbroich (north rhine-westphalia).
about 2,000 m² of concrete surface had to be completely stripped and prepared for a new coating. to achieve a uniform surface in the shortest possible time, besw decided to carry out this work using a trail jet 125, with a working pressure of 2,500 bar, and the surface worker 250 automation tool. since the constant distance to the jetting surface and the constant feed speed made a homogeneous jetting result possible, the complete stripping work was able to be carried out in only about 70 hours.
