Choosing a Slab System: Flat, Beam-and-Slab or Waffle

The slab is usually the largest single element of a building by volume, and the system chosen for it decides the floor-to-floor height, the services strategy and the construction programme long before any reinforcement is calculated. This guide sets out what each system is actually good at, where each one fails, and why on a tall building 200 mm of structural depth can be worth an entire extra floor.
