The evolution of modern structural systems has shifted focus toward sustainability, material efficiency, and improved durability. Bubble Deck slabs, an advanced form of voided reinforced concrete, offer a substantial reduction in dead load by replacing non-functional concrete in the slab’s neutral axis with recycled plastic voids. This study presents a comparative evaluation between Bubble Deck slabs and conventional reinforced concrete (RCC) slabs based on experimental, analytical, and environmental parameters. Durability, flexural and shear strength, long-term strength retention, and material optimization are studied using numerical data and code-based evaluation. Results reveal a reduction of approximately 30% in concrete volume and 27% in steel reinforcement with comparable or superior structural performance. Enhanced durability, minimized cracking, improved stiffness retention, and reduced CO₂ emissions demonstrate that Bubble Deck slabs are a promising alternative for sustainable infrastructure.
