Shed Pads & Slabs Built to Sit Level

A concrete shed pad is only as good as what goes in before the concrete does. Level preparation, adequate compaction, and reinforcement that matches the actual loads are what separate a pad that performs from one that doesn't.

Envision Concrete pours shed pads and slabs for commercial and industrial sheds, rural and agricultural buildings, machinery sheds, large-span structures, and home sheds, garages and carports across Adelaide and the Adelaide Hills. We work with builders, shed suppliers, property owners and homeowners who need a concrete floor that sits level, carries the intended loads, and holds up over time without cracking or settling.

It helps to understand the difference between a shed pad and shed footings, because they are related but not the same thing. A shed pad is the floor slab inside or under the structure. Footings are the separate structural elements that carry column loads into the ground. Most sheds and garages need both, and we pour them together as one job.

Need more room? We also extend existing shed and garage slabs for lean-tos and extra bays. If the project includes a concrete driveway or hardstand approach to the shed, we manage all of it under one contract so nothing falls through the gap between trades.

What We Pour Shed Slabs For

From a backyard garden shed to a large-span machinery shed, every slab is built for what it will actually carry.

Commercial & Industrial Sheds

Slabs for commercial and industrial sheds and large-span structures, reinforced for forklifts, vehicles and racking where needed.

Rural & Agricultural Sheds

Machinery sheds, hay sheds and large-span rural buildings across Adelaide and the Adelaide Hills.

Home Sheds, Garages & Carports

Level, reinforced slabs for backyard sheds, garages and carports, ready for the structure to go up.

Slab Extensions

Existing shed or garage slabs extended for a lean-to, an extra bay or more storage space.

Driveways to the Shed

Scope of Work

What the Job Covers

Every shed pad we pour is managed in full by our team. The same crew handles excavation, levelling, sub-base preparation, reinforcement and the finished concrete surface. There's no gap between who prepares the ground and who pours the slab, which is where accountability problems typically start on split-trade jobs.

More on our team and how we work is on the About page.

Site Level Assessment

Before excavation begins we assess the existing site levels and determine the cut and fill required to achieve a flat, correctly drained pad. Getting this right upfront prevents problems with pooling and uneven finished levels.

Excavation and Sub-Base Preparation

We excavate to the required depth and prepare the sub-base with appropriate material, compacted to specification. This is the most important stage and the one most often done poorly on budget concrete jobs.

Edge Formwork

Formwork is set to level and to the correct pad dimensions. Where edge thickening is required under perimeter walls or columns, this is formed and reinforced separately before the main slab pour.

Reinforcement Supply and Placement

We supply and lay all reinforcement mesh or bar to the required specification. Spacing, cover and placement are matched to the intended load and the engineering requirements for the structure.

Concrete Supply, Pour and Finish

We manage the concrete supply, coordinate the pour, and finish the surface to the agreed specification. Control joints are cut to manage cracking. The pad is left ready for the shed frame to be erected above it.

Curing and First Use

Light foot traffic is typically possible within 24 to 48 hours. We'll give you guidance specific to your slab on when it's ready for vehicles, equipment and the structure above.

What Makes a Shed Pad Fail

Most concrete shed pads that perform poorly weren't poured with bad concrete. They were built on a poorly prepared base, finished without adequate jointing, or specified for a lighter load than the site actually carries. The concrete itself is rarely the problem.

With 30+ years of combined experience, our team has seen the same failure patterns come up repeatedly. Understanding what causes them shapes how we approach every job, from how long we spend on sub-base compaction to where we place control joints in the finished slab.

Each of these issues is addressed in our process before the concrete truck arrives on site.

Inadequate sub-base compaction

A slab poured on poorly compacted fill will settle unevenly as the material below consolidates under load. Cracking follows, and the fix after the fact is expensive. Compacting the sub-base correctly before the pour is the only reliable prevention.

Incorrect finished levels

A pad that isn't properly level causes water to pool inside the structure, affects sliding doors, and can interfere with machinery or racking. Getting levels right takes care during formwork setting, not guesswork after the pour.

Under-specified reinforcement

Reinforcement matched to foot traffic won't perform under forklifts or loaded vehicles. It needs to reflect the actual loads the pad will carry.

Missing or poorly placed control joints

Concrete shrinks as it cures. Without control joints at the right spacing and depth, that shrinkage creates random cracking. Joints don't prevent cracking; they direct it to where it won't matter.
Finishes

Shed & Garage Slab Finishes

Surface finish depends on how the slab will be used. We'll discuss the options as part of the quote, so the finish suits what the shed or garage is for.

Compare All Finishes

Finish options

  • Steel trowelA smooth finish that works for most shed interiors.
  • BroomA textured finish for grip where the slab sees foot traffic and equipment.
  • Exposed aggregateWhere presentation matters, such as approaches and entries. More on exposed aggregate
  • SealingHelps protect the surface and makes it easier to keep clean.
Adelaide Hills

Shed Slabs in the Adelaide Hills

Getting a level slab on a sloping Hills block comes down to the site level assessment: working out the cut and fill needed before excavation, preparing and compacting the base properly, and setting formwork to level so the finished pad drains correctly instead of pooling water inside the shed.

We pour shed slabs and footings for rural sheds, machinery sheds, home sheds and garages throughout the Adelaide Hills, including Mount Barker, Stirling, Hahndorf, Woodside, Lobethal and surrounding towns, as well as right across metropolitan Adelaide.

Common Questions

Concrete Shed Pad FAQs

What is the difference between a concrete shed pad and shed footings?

A concrete shed pad is the floor slab inside or under the shed structure. Shed footings are the separate structural elements that transfer column or wall loads into the ground, typically deeper, narrower, and tied to the frame above. Some projects require both, and some sheds sit on a thickened-edge slab that combines both functions. We can help clarify what your project needs once we know what's being built.

Can you pour the footings and slab together?

Yes. Most sheds and garages need both, and we pour footings and slab as one job, with one crew, one schedule and one point of contact.

Do you pour garage and home shed slabs?

Yes. We pour slabs for backyard sheds, garages and carports across Adelaide and the Adelaide Hills, with the same preparation, reinforcement and finish standard as our commercial work.

Can you extend an existing shed or garage slab?

Yes. We extend existing slabs for lean-tos, extra bays and additional storage. We can also remove an old, cracked slab and pour a new one.

How thick should a concrete shed pad be?

Thickness depends on what the slab needs to carry. A pad used for light storage or foot traffic is typically 100mm. A pad that needs to carry forklifts, vehicles or heavy plant equipment will generally need to be thicker and carry heavier reinforcement. We discuss intended use before specifying anything, so the pad is built for what the site actually requires.

Which finish is best for a shed or garage floor?

It depends on how the space will be used. Steel trowel or broom finish works for most shed interiors, broom adds grip where there's foot traffic and equipment, and exposed aggregate suits areas where presentation matters. Sealing helps protect the surface. We'll talk it through when we quote.

Do you pour shed pads for rural and agricultural sheds as well as commercial?

Yes. We work on concrete shed pads for commercial and industrial sheds, rural and agricultural buildings, machinery sheds, hay sheds and large-span rural structures across Adelaide and the Adelaide Hills. The requirements vary between site types, and we account for that in how we specify and build each job.

How long before a concrete shed pad can be loaded or driven on?

Concrete gains strength progressively after the pour. Light foot traffic is typically possible within 24 to 48 hours. Vehicle access and structural loading should wait until the concrete has reached adequate strength, which depends on the mix design and curing conditions. We provide specific guidance for each job.
