Underground Car Park

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
  
  

Flooring systems: Sikafloor®MultiFlex PB-21 and PB-51 - greycolored broadcoast systems. They have the following features:

• Crack-bridging at low temperature
• Primer with low-viscosity, colorless two-component material
• Highly elastic
• Chemical, abrasion and slip resistant
• Waterproofing
• Color options

Floor joint system: Sika®FloorJoint PB-30 PD. The system has the following features:

• High mechanical and chemical resistance, non-corroding
  
• Waterproof system design possible
• For gaps in the substrate with a max. width of 60 mm (max. positive joint movement = 40 mm)
• Grindable profile for level integration into the floor surface
• Hardly any vibrations noticeable under direct car traffic
• Thermal expansion coefficient similar to resin-based floors
• Easy to install / easy to repair / short downtime / trafficable after 24 h
