The Concrete Building Revolution                                               
BubbleDeck creates a prefab two-way hollow slab deck in which plastic balls -‘bubbles’- keep concrete out of zones where it has the least carrying effect. This results in dramatic overall weight reduction, so that larger spans and overhangs can be achieved.

The bubble diameter and the layout of the welded reinforcement rebar mesh are configured relative to the thickness of the required surface (floor) so that the ultimate concrete construction is obtained with maximum positive effect against flexion and shear forces.

Illustration 1. shows how the BubbleDeck ‘ball cage’ is configured and assembled.
Its two unique components, the balls and the welded reinforcement rebar mesh, together with the rebar girders connecting top and bottom mesh, ultimately form the geometrically stable BubbleDeck element.

Illustration 2. shows the ball cage being cast in a thin layer of concrete, which replaces on-site subsurface formwork and which remains an integral part of the finished deck.
During on-site pouring the rebar mesh retains and locks the bubbles in exact position to ensure even distribution of concrete.

The result is a monolithic two-way hollow deck with superior surface bearing properties.
