Strip footings
This slab is supported by strip footings. Strip footings are also called 'edge beams'. A footing slab requires two separate concrete pours. It can only be used on Class A and Class S sites.
Advantages of footing slabs are that they:
- adapt to sloping sites
- require simple formwork (no edge rebates)
- require simple excavation that is exposed for minimal time
- do not require internal beams.
The fill material is usually restrained at the external walls. Therefore these walls need to be strong enough to support the fill.
