What excavator do I need for a shed slab?

Shed slab construction requires excavating the slab footprint to remove topsoil and organic material, establishing correct levels, and preparing the compacted base. For a standard residential shed slab (6m x 9m), the 1T or 1.7T mini excavator is the most common choice. The excavation depth is typically 150–300mm depending on topsoil depth and slab design. The 1T mini excavator is sufficient for smaller shed slabs and fits through standard residential gates. The 1.7T is faster for larger slabs. For large commercial shed slabs or slabs requiring deep excavation, the 3.5T excavator is more efficient. A tipper truck is commonly hired alongside the excavator to remove excavated topsoil. For slabs with strip footings, the excavator can also dig the footing trenches to the required depth.
