Frequently Asked Questions About Concrete Slab For Shed in Salisbury
How much will 20kg of concrete cover?
A 20kg bag of premixed concrete ($9–$14 at retail) covers about 0.1 square metre at 100mm thickness, or roughly 10 litres of wet mix. For a shed slab you need batched truck concrete instead: a typical 3x3m base at 100mm thick needs about 0.9 cubic metres, equal to roughly 90 bags.
What is the 4 2 1 rule for concrete?
It's the classic hand-mix ratio: four parts gravel, two parts sand, one part cement. That's fine for small footings but not a shed slab, since backyard mixing can't guarantee consistent strength across the pour. Shed slabs should use batched N20–N25 concrete ordered from a plant and reinforced with mesh.
Is concrete the same as cement?
No. Cement is the powder binder, about $9–$15 per 20kg bag, that mixed with sand, gravel and water becomes concrete. A shed slab is concrete, not cement: for a typical 3x3m base you'd order around 0.9 cubic metres of batched concrete rather than hand-mixing individual bags.
How much does a concrete driveway cost in Australia?
A standard concrete driveway costs $65–$150/m² depending on thickness, reinforcement, finish, and location. A double driveway of ~50m² typically costs $3,500–$7,500. Exposed aggregate and decorative finishes cost more than plain broom-finished concrete.
How thick should a concrete slab be for a driveway?
Residential driveways should be a minimum 100mm (4 inches) thick with SL72 or SL82 mesh reinforcement. For areas with heavy vehicles or truck access, 125–150mm with rebar reinforcement is recommended. Thicker slabs are needed for reactive soils.
How long does concrete take to cure?
Concrete reaches about 70% strength in 7 days and full strength at 28 days. Light foot traffic can resume after 24–48 hours. Vehicles should wait at least 7 days. In cold weather, curing slows significantly — your concretor may use curing compounds or covers.
What is exposed aggregate concrete?
Exposed aggregate concrete has the top layer of cement paste removed (by washing) to reveal the stones within the mix. It's popular for driveways, paths, and pool surrounds as it provides a decorative finish with natural slip resistance. It costs 15–25% more than plain concrete.
Why does concrete crack?
All concrete eventually cracks due to shrinkage, thermal movement, or ground movement. Control joints are deliberately placed every 3–4 metres to direct cracking. Cracks wider than 3mm or that are heaving or sinking indicate a structural issue requiring assessment.
