Bubble Deck

Prefab 3" semi cast concrete panel typically 8' widex 40' long


  • off site manufacturing


  • prefab panels or prefab cages

  • on site assembly

  • less materials in forms/concrete

  • less depth section

  • less beam work

  • saves time


The goal is to produce a floor slab that can achieve longer spans with a continuous, “flat plate”  underside. 


Build More With Less

Stay in Place Form that is prefabricated as a semi pre-cast slab,  typically 8-10 feet wide x 40 feet long.

Hollow plastic balls are inserted into the slab and held in place by reinforcing steel embedded into 3" concrete. The end result eliminates the use of concrete that has little carrying effect while maintaining the two-way span (biaxial) strength.


Reduced Overall Cost

eliminates up to 35% of the structural concrete. When coupled with the reduced floor thickness and facade, smaller foundations and columns, construction costs can be reduced by as much as 10%.


Faster Construction

With virtually no formwork, no downturn beams or drop heads, and fast coverage of typically 320ft2 per panel, means floor cycles up to 20% faster than traditional construction methods. Regardless of project size, shape or complexity; simply shore, place, and pour to quickly install concrete decks.


Lower Risk

Off-site manufacturing, fewer vehicle trips and crane lifts as well as simple installation all combine to minimize operating risks, as well as lower health & safety risks. 


LEED Compatible

system offers a wide range of advantages in building design and during construction. There are a number of green attributes including; reduction in total construction materials, use of recycled materials, lower energy consumption and reduced CO2 emissions, less transportation and crane lifts that make it more environmentally friendly than other concrete construction techniques.
