The Lightweight Biaxial Slab

The engineering solution that radically improves building design and performance while reducing the overall costs.

The BubbleDeck system is based upon the patented integration technique - the direct way of linking air and steel.

By adapting the geometry of the ball and the mesh, an optimised concrete construction is obtained, with simultaneous maximum utility of both moment and shear zones.

The construction literally creates itself as a result of the geometry of two well-known components: Reinforcement and hollow plastic balls. When the top and bottom reinforcement are linked in the usual way, a geometrical and statical stable BubbleDeck unit evolves.

The reinforcement catches, distributes and locks the balls in exact position, while the balls shape the air volume, control the level of the reinforcement, and at the same time stabilise the spatial lattice. When the steel lattice unit is concrete, a “monolithic” biaxial hollow slab is obtained.
