Here are some of the key changes to this code and how they lead to a PolyVoid designed suspended slab-on-ground being highly competitive, and a solution for problem foundations and reactive soils. The footing systems for which designs are given include slab on ground, stiffened rafts, waffle rafts, strip footings, pad footings and piled footings. Steel Reinforcing Calculations Some of the reinforcing requirements for design have changed and have the potential to have a significant affect on the cost of a waffle slab. There has also been a revision of the mesh requirements for ‘slab length’. It is measured in millimetres and suggests the value of which the soil might move due to changes in moisture.
