Ribbed and waffle slabs provide a lighter and stiffer slab than an equivalent flat slab, reducing the extend of foundations. They provide a very good form where slab vibration is an issue, such as laboratories and hospitals.
- Relatively light, therefore less foundation costs and longer spans are economic speed of construction.
- Fairly slim floor depths.
- Excellent vibration control.
- Thermal mass.
- Good for services integration.
- Durable finishes.
- Fire resistance.
