Concrete guide
Thickness intentConcrete thickness guide
Concrete thickness should match the job: slab, footing, or small structural fill. This guide keeps the recommendation tied to the actual pour type.
Use this for
- Slab depth checks
- Footing depth checks
- Small pour planning
Common ranges
Practical thickness ranges
Shed bases and patios
Thin slabs are usually enough when the slab is lightly loaded and the subbase is stable.
Garage slabs
Garage floors usually need a bit more thickness than a small patio because the loads are higher.
Footings
Footings are governed by width and depth rather than thin slab behavior.
