The Mercedes-Benz Arena in Stuttgart with its new membrane roofing.

All 40 segments of the filigree roof construction were replaced during the renovation phase.

Multiple groups worked in concert on the different phases, removing the old membranes, rust-proofing the roof’s steel framework, installing the new membranes, and upgrading the drainage system.

PFEIFER’s experts were responsible for renovating the stadium roof.

PFEIFER outfits Stuttgart’s Mercedes-Benz Arena with a new membrane roof

A first-class stadium roof for a first-class football squad – VfB Stuttgart leveled up into the 1st German Bundesliga, and its hometown Mercedes-Benz Arena got a fitting upgrade too with a new roof over the summer break. The project to replace the 25-year-old membrane roofing cost just under ten million euros and was finished on schedule, just in time for the first home game. PFEIFER Seil- und Hebetechnik from Memmingen was in charge of the renovation project.

During the multi-week construction phase, all 40 segments of the filigree roof construction, spanning over 37,000 square meters, were removed and replaced. Every day an international team of up to 80 climbers worked in parallel on four different stages. One group removed the old membranes, while a second rust-proofed the roof’s steel frame. A third installed the new membranes, and the fourth completely upgraded the drainage system. 

A roof with the power of titanium

The new membrane was manufactured by the Chinese PFEIFER subsidiary Covertex and was the largest German contract for the membrane specialists from Shanghai since the PFEIFER takeover two years ago. The PVC membranes used were coated with titanium oxide. This innovative finish ensures the membranes last longer, clean easier and stay bright white despite the effects of the weather.   The rope support system PFEIFER installed in the Mercedes-Benz Arena in the early 1990s is still in excellent condition, and remained in place throughout the renovation work. Just a few individual elements were cleaned and reused as part of the project. 

 “Proud of the entire team”

“I am proud of what the entire team achieved,” Cable Structures Business Unit Head Christian Schlögl says. “We got a really complex project done in a fairly short period of time and right on schedule.” The project was initiated by client and stadium owner, Stadion NeckarPark GmbH & Co. KG. Engineers from schlaich bergermann partner sbp GmbH were responsible for planning and overseeing the construction, while asp Architekten GmbH served as project planner and manager.
