VoidDeck is a connected network of egg-shaped spheres, used as a void in concrete slabs. By removing unstructual, dead weight concrete, VoidDeck slabs are lighter and perform better than solid slabs.
VoidDeck is used in any residential or thin slab application to replace typical 7-9 inch slabs. VoidDeck is the easiest void concrete method to implement. VoidDeck works well with PT applications and reduces concrete volumes by 20%.
VoidDeck allows you and your team to build wider spans and more innovative designs.
Architectural flexibility is greatly improved since columns and beams no longer have to hold the deadweight of structural concrete. Large, unobstructed floor plans are now possible.
For developers and contractors, VoidDeck is lightweight and easy to install.
VoidDeck is prefabricated off site and delivered in proper sequence to make the construction process simple and organized.
Unlike other void concrete systems, VoidDeck is fabricated up to 3x faster, since individual balls are replaced with a large net. Tie downs are also not required, so costs are significantly reduced.
The concern for improved environmental building methods is growing amongst consumers. VoidDeck allows you to build with 30% less carbon emissions in addition to having better thermal insulation properties. With an r value of 9, compared to a solid slab’s value of 30, VoidDeck is the most sustainable concrete building method.
Additionally, VoidDeck has sound damping properties which further improves the living experience.

Cost. Despite the number of benefits void concrete has, the final decision maker is almost always cost. Because of the time and labour required for fabrication, void systems have had a slow start in North America. Developers needed to weigh the pros of voided slabs with the additional labour cost required.
However, we have solved that problem by replacing individual voids with our VoidDeck. InfinaTec slabs are not only cheaper than every void concrete system on the market, but are actually cheaper to produce than traditional concrete slabs. InfinalTec requires LESS concrete and LESS labour.
