A waffle mould slab is a reinforced concrete slab system formed using specialized moulds to create a grid-like (waffle) pattern on the underside. This design reduces the overall weight of the structure while maintaining high strength and load-bearing capacity. Waffle slabs are commonly used in commercial buildings, industrial structures, and large-span constructions. They help reduce concrete consumption and construction costs. The system also improves structural efficiency and provides better thermal and sound insulation. Waffle mould slabs are ideal for projects requiring durability, economy, and long spans.
