Awarding of quality certificate – Gütezeichen Kanalbau

Our clients demand high standards in the field of sewer construction from the companies carrying out the work. IWR GmbH, too, has decided to have its work reviewed externally by the Gütegemeinschaft Kanalbau on a regular basis. We are very proud to have been awarded the ‘Sewer Construction Quality Certificate‘ for the tendering and supervision of open trench sewer construction measures in 2016.
