The area is cleared of grass, debris, and old concrete if needed. The ground is then excavated and leveled to create a strong, stable base for the new shed slab.
A layer of compacted gravel or crushed rock is added for support. Steel mesh or rebar reinforcement is installed to strengthen the concrete and prevent future cracks.
Timber or metal formwork is set in place to define the shed slab’s shape. Expansion joints are added to allow natural movement, preventing cracks over time.
Concrete is poured, spread, and leveled for a smooth surface. Depending on the finish, it is brushed, exposed, smudged, or coloured to achieve the desired look.
The concrete cures for at least 7 days, with moisture control to prevent cracks. A protective sealer is applied to enhance durability and resist stains or wear.

A well-installed and maintained shed slab can last 30 to 50 years, depending on the quality of the concrete, reinforcement, and environmental factors.
For most garden sheds, a 100mm (4 inches) thick slab is sufficient. For heavy-duty sheds or machinery, 125-150mm (5-6 inches) with reinforcement is recommended.
Lightweight storage is fine after 48 hours, but for heavy items, machinery, or vehicles, it’s best to wait 7 days for the concrete to fully cure.
Keep it clean and free of debris, reseal every 2-3 years, and avoid using harsh chemicals or heavy impacts that could cause surface damage.
Use reinforcement like steel mesh or rebar, ensure proper ground preparation, and include control joints to allow for natural expansion and contraction.
It’s possible, but proper leveling, reinforcement, and curing are crucial. A professional install ensures long-lasting strength and prevents costly mistakes.
Prices vary, but expect to pay $75-$120 per square metre, depending on thickness, reinforcement, and site preparation needs.
