Sika supplied the flooring systems and the floor joint systems in this project. The carpark serves a new-built office and residential building. The modern apartments in the building were designed to have either sunny balconies, terraces or private gardens, and parking lots.

Project Requirements

The flooring systems for the park deck are required to be:

  • Crack bridging according to the OS norms
  • Abrasion resistant for the car traffic
  • Corrosion resistant
  • Watertight joint profiles for the numerous joints in the concrete substrate to provide long-term protection.
  • Chemical resistance to petrol and diesel fuels, engine oils, urea solutions, saturated saline solutions and lubricants in accordance with the construction and testing principles of the Deutsches Institut für structural engineering
