Getting a shed slab done right in Brisbane is more involved than most people expect. Brisbane’s reactive clay soils, summer storm loads and council requirements all affect how your slab needs to be designed and poured. Get it wrong and you’ll deal with cracking, movement and a shed that won’t sit level within a few years.
At Brisbane Budget Concrete, shed slabs are one of our most requested jobs. We know what Brisbane soil does to a poorly built base and we know how to stop it happening to yours. Whether it’s a garden shed, a workshop, a garage or a large storage structure, we’ll quote you promptly and get it done properly.
The foundation is the most important part of any shed build. A slab that moves, cracks or holds moisture will cause the structure above it to deteriorate far sooner than it should. Brisbane Budget Concrete has poured shed slabs across Brisbane and South East Queensland for many years. We use the correct grade concrete, properly chaired steel reinforcement and we build in the drainage and control joints that Brisbane’s climate demands. The result is a slab that stays flat, stays solid and gives your shed the platform it needs to last.
Slab thickness for a shed slab in Brisbane depends on what you’re building on top of it. For a standard garden shed, a 100mm slab with SL72 mesh reinforcement is typically sufficient. For a workshop with heavy equipment or a car hoist, you’ll need at least 125mm to 150mm with heavier reinforcement. For a large farm shed or commercial storage structure, an engineer’s report may be required.
Brisbane Budget Concrete recommends the right specification for your shed slab based on your site conditions, load requirements and any council approvals that apply.
Most residential shed slabs in Brisbane fall into three common size ranges. A small garden shed slab typically runs 10 to 15 square metres. A double garage or workshop slab commonly runs 36 to 60 square metres. A large storage shed or multi-vehicle garage can be 80 square metres and above. Each size range requires different drainage planning, reinforcement specification and joint placement.
Shed slab costs in Brisbane generally range from around $65 to $100 per square metre for a standard residential pour. Sites with difficult access, significant fall, reactive soil or engineering requirements sit towards the higher end of that range. Brisbane Budget Concrete provides free on-site fixed-price quotes. No surprises when the invoice arrives.
In most Brisbane City Council areas, sheds over 10 square metres in floor area require a building permit. Your shed supplier can confirm the specific requirements for your suburb. Brisbane Budget Concrete works with your builder and certifier to ensure your shed slab meets all approval requirements.
We factor all of this into your quote upfront so there aren’t any surprises on the day.
Brisbane’s wet season runs from November through March. Rain and saturated ground can delay a shed slab pour by weeks. If you’re planning a shed build for spring or summer, get Brisbane Budget Concrete locked in early so your project starts on time and doesn’t get caught in the backlog.
