3,250 m² of wall surface and 2,100 m² of floor surface needed decoating and roughening for re-coating in the rheinhausen sewage treatment plant.
marschmann gmbh used two falch trail jet 125 with 3,000 bar working pressure, as well as two surface worker 250, to do exactly that. preparation of the substrate was completed in just a few days.
dirk jansen, a project manager at marschmann, remarked: "it’s unbelievable how fast it worked – and we had a super-even surface. our employees were also thrilled that no manual sandblasting work was needed."
