In October 2021, Unidome was able to present an extraordinary project: the world's largest span with a sustainable voided biaxial slab. As part of the new Loxone Campus in Kollerschlag, Austria, a lecture hall with an impressive roof of 33 x 21 meters realized. The 90 cm thick, slightly curved reinforced concrete slab is a architectural and engineering masterpiece, which is achieved through the use of Unidome XS-D3 concrete shaper elements became possible.
With this slab alone, 72 m³ concrete, round 180 tons of dead load and 15 tons of CO₂ emissions could be saved. In the entire project, thanks to Unidome concrete shapers more than 125 tons of CO₂ emissions avoided — clear proof of Material efficiency, resource conservation and climate protection impactof technology.
The used Unidome voided biaxial slab is based on the principle of bidirectional load. Load-free areas in the slab are displaced by recycled plastic voidformers, which at the same time as lost formwork remain in the component. This system enables significant concrete savings while maintaining the same load capacity. Thanks to the uniform load distribution, even exceptional Spans and column-free spaces Implement what an enormous Freedom of design in architecture opened.
The advantages of this construction method are manifold:
The project on the Loxone Campus impressively shows how the combination of Lightweight construction, climate protection and innovative engineering technology leads to new standards in concrete construction. Die Unidome voidformer technology is therefore a key to the future of construction — efficient, sustainable and versatile.
