    DELTA® in the Gotthard Tunnel!

    On June 1, 2016, the 57-km Gotthard Tunnel was officially opened in Switzerland. The materials used in building the world's longest railway tunnel include our high-performance drainage sheets DELTA®-AT 800/1200. Compared to the old Gotthard tunnel, the new link features two tubes, so that more trains can run through it at greater speed. Carrying a price tag of around 11 billion euros, the building of the tunnel took 17 years.

  • A perfect fit

    A perfect fit

    Developed especially for hip roofs, the new DELTA®-MAXX WD high-performance sheet ensures an exact fit, greater safety, and optimum installation efficiency. The two adhesive strips integrated in the underside make the installation of the sheet noticeably easier and significantly faster than that of conventional sarking sheets. Thus, roofs will be safely covered and also optimally protected from weather influences.
