Voided Slab System (Volimax Lightweight Flat Slab Technology)

The Volimax voided slab system reduces the slab’s self-weight by embedding air pockets within the concrete without compromising performance. It enhances earthquake resistance and enables large spans without beams. Delivered as nested formwork modules, it ensures fast and efficient installation on-site.

• Up to 25% structural weight reduction – Up to 30% seismic load reduction • Spans up to 16 m with minimal slab thickness • Beamless flat ceiling – Clear pathways for MEP installations • Compatible with precast and post-tensioning systems • Fast installation – Simple removal – Site efficiency
