GRC balconies

Detailed individual design

Detailed individual design


Balconies from BB fiberbeton are manufactured to order in individual design. The formability of GRC allows the balcony to adapt to the architecture of the building and city surroundings. The elements come with details such as edges, recesses, and cantilevers.

Balconies in GRC consist of a load bearing steel structure that is then “cladded” with GRC. Often a balcony floor with non-slip pattern and a ceiling with upward returns that encapsulates the steel structure. It looks like a solid concrete balcony but is in fact a lightweight structure better for the environment and the building it is attached to.

Balcony bases or floors can be produced with embedded drainage system – drop over the front, drop to water gutter with in-casted drain, or other solution matching the need of the project. Besides balcony bases, we also often produce balcony parapets.

Mounting principles

Our typical facade cladding is produced with one of the following mounting systems or a combination of same.

  • Stud-frame (embedded steel frame)
  • Embedded steel brackets
  • FA1000®
  • Embedded inserts
  • Recessed holes with plugs

Most of our facade solutions utilise the material’s possibilities for mounting without visible screws and with fewest possible loose parts. This achieves a finished result that appears to be monolithic and which technically requires a minimum of maintenance.

Facade elements are usually mounted as building envelopes with a ventilated back side. The assembly method itself varies according to the element size and the nature of the underlying supporting structure. On smaller elements, fittings are cast on the back and the element is mounted as a “radiator” – On larger elements, a load-bearing steel frame is embedded which then delivers the forces where it is possible.

Vertical joints are often performed with traditional element solutions: expanding joint strips etc. – or overlap. Horisontal joints are typically vented so that lower elements go under the overhanging element.

All our technical solutions are tried and tested.
