BubbleDeck Technology
Redefining the Slab.
Reinventing the Standard.
What is BubbleDeck?
BubbleDeck is a two-way voided slab system that replaces heavy, solid concrete with strategically
positioned recycled plastic balls, eliminating concrete where it’s structurally unnecessary.
The result is a lighter, stronger, greener floor system — designed for long spans, faster installation, and reduced structural mass.
How It Works
- Void-Forming Innovation
Recycled plastic spheres are embedded in the low-stress center of the slab, reducing weight while preserving full bending strength.
- Two-Way Load Distribution
A top-and-bottom steel mesh grid enables true biaxial force distribution — eliminating internal beams and enabling longer, beamless spans.
- Cast-in-Place Integration
Semi-precast panels arrive at site ready to install, then monolithically poured to achieve full slab continuity.
The result? A floor that behaves like a two-way flat slab — only lighter, faster, and smarter.
Why BubbleDeck Works Better
–35% Concrete
Less dead weight = smaller structure, lower foundation loads
Longer Spans
More design flexibility,
fewer columns
Beamless Flat Soffit
Clean ceiling lines, easier MEP
and future renovations
Faster Install
Semi-precast delivery enables quick
on-site casting
Seismic Resilience
Lighter weight = lower seismic force
+ better drift performance
Greener Footprint
Lower embodied carbon and use
of recycled materials

Span performance depends on load conditions and support layout.
Certifications & Compliance
We deliver BubbleDeck systems engineered not only for performance — but for compliance with international standards.
Every slab we provide is backed by structural science, material testing, and country-specific approvals.
Structural Design Compliance (Eurocode 2 & ACI)
BubbleDeck is officially incorporated into the European design standard Eurocode 2 and is fully compatible with ACI (American Concrete Institute) guidelines. This means it can be treated and designed like a homogenous solid slab — ensuring simplicity for engineers and trust for owners.
Fire Resistance: REI 120 Rating
BubbleDeck slabs meet REI 120 fire performance requirements — meaning they maintain load-bearing capacity (R), integrity (E), and insulation (I) for at least 120 minutes during a fire. This provides critical protection in both residential and commercial buildings.
Vibration Control (VC-C Certified)
BubbleDeck achieves vibration performance levels suitable for sensitive uses like hospitals, laboratories, and offices. It meets or exceeds VC-C vibration criteria, offering a comfortable environment even under dynamic load conditions.
Thermal Performance (Up to +39%)
While not a formal insulator, BubbleDeck improves thermal resistance by 17–39% compared to solid concrete slabs of equal thickness — due to the internal air pockets. This contributes to energy savings and a more comfortable indoor environmentBD_ThermalResistance.
Acoustic Performance (Airborne&Impact)
The voided structure helps reduce airborne sound and dampens impact noise. Acoustic lab tests (available upon request) confirm its advantages over hollow-core planks or thin prestressed slabs, particularly in residential or multi-floor settings.
Where It’s Used
BubbleDeck is adaptable to nearly all building types — not just mega-projects.

Residential
Beamless ceilings, fewer columns, flexible layouts, and faster construction for townhomes and high-end homes.

Commercial
Open office floors, easier MEP, future-proof floor plans.

Industrial & Warehouse
Large spans without heavy beams; load-bearing floors for logistics.

Institutional
Hospitals, schools — improved vibration control and seismic behavior.

It may look like just a plastic bubble
— but there's precision inside.
Behind each BubbleDeck slab is a structural logic refined through years of international research, testing, and real-world application. The positioning, spacing, and detailing of each void is the result of patented engineering — not guesswork.
That’s why only systems licensed by the original inventor can guarantee performance at the highest level.
As Thailand’s exclusive licensee, Stact delivers every slab with full technical backing from the international BubbleDeck team — ensuring compliance with global standards and local conditions alike.
