Question 1

What thickness is required for a shed concrete slab?

Accepted Answer

A standard residential shed slab is typically poured at 100mm thickness. For machinery, vehicle storage, or heavy workshop use, 125mm with SL82 mesh is recommended. A site inspection to assess soil conditions is important — reactive clay soils in Adelaide's northern suburbs often require a thicker, reinforced slab.

Question 2

Do I need a council permit for a shed slab in SA?

Accepted Answer

A shed slab itself usually does not require a permit, but the shed structure may. If the shed is over 10 m² and requires a development application, the slab will be included in that assessment. Kenset Construction works alongside shed suppliers and building certifiers to coordinate the slab and permit process.
