Bubbledeck Technology

Redefining the Slab.
Reinventing the Standard.

BubbleDeck is a biaxial voided slab system that strategically places recycled plastic spheres inside the slab
to eliminate unnecessary concrete. The result is a lighter structure that maintains full strength while offering
faster installation, longer spans, and greener outcomes.

Client Testimonials

See What Others Are Saying
Reducing the overall structural weight by up to 20% has a significant positive impact on earthquake resistance. It helps lower the forces involved, reduce building sway, and significantly lessen the damage to the structure

Assoc. Prof. Chatpan Chintanapakdee

Ph.D., expert in earthquake-resistant structures, Department of Civil Engineering, Chulalongkorn University.
We may not be able to avoid earthquakes, but we can prepare our buildings to withstand them. Reducing structural weight is one of the most effective methods. The lighter the mass, the lower the inertial force, which means less load on the structure. This improves the building’s earthquake resistance and lowers the risk of collapse.

Mr. Somsakdi Seubsai

Senior Vice President of Engineering Design, Stonehenge Co,. Ltd.
Stact (BubbleDeck) gives us great freedom in design. Many ideas that were once just concepts can now actually be realized. Most importantly, it complies fully with engineering principles, so we can build with peace of mind. As a bonus, it significantly reduces material usage—making it environmentally friendly as well.

Mr.Prachaya Charoencharaskul

Managing Director TONG CHARAS SAENG COMPANY LIMITED Project: PARK91 and AURORA VILLAGE
From our experience using the BubbleDeck structural floor system, we found it to be an innovative and modern solution.It can be installed quickly, reduces construction steps, and significantly saves both time and costs compared to traditional beam-slab systems. Additionally, it simplifies on-site operations as materials do not need to be stockpiled at the construction site, thanks to direct delivery from the factory along with clear and easy-to-understand installation instructions.Moreover, factory production ensures greater confidence in quality control and standards. This system is well-suited for advancing industrialized construction technologies, reducing the reliance on labor—especially in areas with labor limitations—and enabling faster construction overall.

Mr.Panote Mongkoltummakul

Managing Director PMEC ENGINEERING CO.,LTD.
I think this system is easy to install, works quickly, and is simple to use. Also, I find it to be quite strong — it feels even stronger than the beam system, because after the concrete is poured over the slab and columns, everything becomes a single solid structure.

The bubbledeck helps reducing the construction cost and time by replacing the formwork. It also helps reducing the carbon footprint by reducing the concrete quantity in slabs and the foundation system.
