BUBBLEDECK system is a revolutionary construction method by eliminating concrete from the neutral axis of a floor slab that is structurally not performing, as a result dramatically reducing in Dead Weight.

The BUBBLEDECK system is based upon patented integration technique - the direct way of linking air and steel. Void formers inside the flat slab eliminate at least 30% of a slab’s dead weight.

Incorporation of recycled plastic bubbles as void formers allows wider space between columns. Combination of this with a flat slab construction approach spanning in two directions - the slab is connected directly to insitu concrete columns without any beams - produces a wide range of cost and construction benefits.

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, optimised concrete construction is obtained, with the 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 an 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.





In the precast half-slab BUBLEDECK system, the bottom side of the 'bubble-lattice' unit is furnished with a pre-cast concrete layer which on the building site replaces the horizontal part of the formwork.

Where the bottom of the bubble-reinforcement sandwich includes a 60 mm thick precast concrete layer acting as permanent formwork within part of the finished slab depth replacing the need for temporary formwork. The elements are placed on temporary propping, loose joint, shear & edge reinforcement added, perimeter and tolerance joints shuttered and then the remaining slab concreted.

Most commonly specified is suitable for the majority of new-build projects. Requires fixed or mobile crane to lift into position due to the weight of manufactured elements as delivered to site.
