One of the most recent and very interesting projects KNOPP worked on was the renovation of the Alfa Romeo museum in Arese, Italy. Built on an impressive surface of 4,800m2, spread over 6 levels, you can see how the design of Alfa Romeo vehicles evolved to what it is today. As part of the extensive construction measures for the rehabilitation of the museum, various screed works had to be carried out.
ARDEX, the Witten-based construction chemicals specialist is taking up a majority stake in the Knopp Group of Companies. It is expected that the transaction will be completed at the end of September. Both companies will continue to operate independently. The family shareholders who are currently actively involved in the management will retain substantial stakes as shareholders in the future.

The new Port House in Antwerp repurposes, renovates and extends a derelict fire station into a new headquarters for the port – bringing together the port’s 500 staff that previously worked in separate buildings around the city. Zaha Hadid Architects' design is informed by detailed historical research and a thorough analysis of both the site and the existing building. All floor screeds were equipped with CONTOPP® Fibercompound Duremit hydro. [more]
