The 40-year-old Arabella skyscraper in Munich was damaged by cracks, spalling and frost damage on some balconies and balustrade panels. These affected the durability and safety of the balconies and the building's surroundings. During the repair work, the complex geometry of the facade was to be maintained without scaffolding where possible while the building continued to be used. The ideal solution here was a covering of carbon reinforced concrete. The low material requirement allowed outdoor work by industrial climbers. A textile concrete layer of only 6 mm ensured both the preservation of the old appearance and long-term load-bearing capacity.
