Sustainability & Knowledge
Lighter Structures, Higher Efficiency, Lower Emissions
We reduce material consumption and CO₂ emissions through more efficient voided slab Systems — supporting sustainable construction decisions without compromising structural performance.
The Max Span Advantage
Sustainability & CO₂ Reduction
Reducing carbon emissions is a key priority in modern construction. Max Span’s Voided Slab Systems contribute to sustainability through:
Up to 30% reduction in concrete usage within the slab
Lower CO₂ emissions through reduced material consumption and the use of recycled materials
Fewer concrete trucks on site, improving logistics and reducing traffic impact
Lighter, more efficient structural solutions that enhance project sustainability
System Efficiency
Engineered voids replace non-structural concrete to improve slab efficiency.
Smarter Design, Lower Environmental Impact
The construction industry is one of the largest contributors to global carbon emissions — creating a real challenge across both design and execution.
At Max Span, we address this challenge through advanced structural Systems that reduce non-effective concrete within the slab — lowering material consumption and improving overall building efficiency.
Voided Slab Systems are designed to support the shift toward more sustainable construction, while fully maintaining structural safety and performance.

Material Efficiency
Less concrete means lower resource and energy consumption

Reduced Transportation
Fewer concrete trucks on site, reducing congestion and emissions
Measured Impact
A direct comparison between traditional Systems and Max Span’s voided slab solutions — based on key structural and environmental performance indicators.

Weight Reduction
Up to 30% lighter slabs, reducing loads on columns and foundations — while lowering concrete consumption and excavation work.

Recycled Materials
D-MAX and Foermli Systems utilize recycled plastic components to create internal voids within the slab — reducing waste and extending material lifecycle.
Sustainability is no longer optional — it’s an engineering standard measured by numbers.

Lifecycle Benefits

Design Phase
Optimized structural design from the start — reducing material quantities and improving resource efficiency.

Construction Phase
Faster execution with reduced on-site waste and lower concrete usage and transportation — minimizing immediate environmental impact.

Operation Phase
Lighter structures reduce overall building loads, improving cooling efficiency and long-term energy consumption.

End-of-Life Phase
Easier dismantling and better material separation — enabling recycling and reducing construction waste.
