Balconies are being produced by negative technique. By doing so the incline is provided within the formwork. Therefore, the walkable surface of each balcony is on the bottom of the formwork and provides an optimized polished surface and a precise drainage. The reverse side of each balcony is being smoothened manually and therefore provides an even surface.
Advantages at a glance
- polished surface from negative formwork technique
- with or without upstand
- structural energetic separation due to integration of isolation components into balcony
- precise drainage due to negative formwork technique
