Prinzing GmbH, 89143 Blaubeuren, Germany

Production of milled monolithic manhole basessuccessfully commenced


The Ruf concrete production facility in Germany has been in existence for more than 120 years and are well known for innovative and efficient solutions in construction work. In their Wilburgstetten production facility, concrete pipes and precast manholes are produced on a large scale. Ruf’s attention was drawn to the new Primuss manufacturing process for monolithic manhole base units - made by Prinzing from Blaubeuren, Germany - on account of several articles in the relevant press and, in particular, a report published in CPI 04/2008. Ruf formerly manufactured manhole bases upside down on a Prinzing Tornado with the drain channel being inserted manually afterwards. After making several visits to a Primuss pilot plant at Prinzing’s headquarters and carrying out profitability calculations, Ruf became convinced of this new technology’s value because of the quality increase in the monolithic manhole bases.
