Shed, Garage & Carport Slabs, Poured to Last

The right thickness, reinforcement and prep for whatever's going on top — set out to your shed kit and managed end to end.

The Foundation Your Structure Depends On

A good shed, garage or carport slab is not just a flat pad — it is a structural element. Get the thickness wrong, skip the reinforcement, rush the sub-base, or set it out inaccurately and you create problems that follow you for the life of the build. Get it right and the frame goes up on a solid, stable base that lasts.

Building concrete slabs across Greater and Western Sydney since 2012, we handle the whole job — excavation and sub-base preparation, accurate set-out to your shed kit's hold-down points, formwork, steel reinforcement, the pour, and the finish. One team manages the job from start to finish, with one point of contact and one crew accountable for the result.

  • Correct thickness and reinforcement for the intended load
  • Accurately set out to your shed kit's anchor or hold-down plan
  • Rebates and edge thickenings formed where required
  • Proper excavation and compacted sub-base — the work most people can't see
  • Fixed-price quote within 24 hours — no deposit to quote, no obligation

Shed, Garage & Carport Slabs

Each structure has its own requirements. Here is how we approach the three most common jobs.

Shed Slabs

We set out the pad to match your kit's bolt-down or hold-down point locations so the frame lands correctly on the finished slab. Where the kit calls for it, we form rebates along the edges so the shed wall sits flush with the slab face. Sub-base is prepared and compacted before any steel or formwork goes in.

Garage Slabs

Garage slabs carry vehicles, so thickness and reinforcement are specified for the load. We tie the slab into the garage build and coordinate the set-out with your builder or frame supplier. The finished surface is smooth and level — ready for the frame and for years of daily vehicle use.

Carport Slabs

Carport slabs need to drain correctly, handle vehicle loads, and finish neatly to the posts or structure above. We set the falls so water moves away from the structure, use the right reinforcement for the ground conditions, and finish the surface to suit — whether that is a plain finish or something more decorative.

Everything in the One Job

From excavation to finished surface — managed by one team, one point of contact, accountable start to finish.

Shed Slabs

Set out to your kit's anchor plan, with rebates and sub-base prep included as required.

Garage Slabs

Thicker, reinforced for vehicle loads, tied to the build and set out to suit your garage frame.

Carport Slabs

Durable, drained and finished to suit the structure — set correctly so water moves away from the posts.

Edge Thickening & Rebates

Formed where specified by the engineer or required by your shed kit — providing the bearing and flush-fit the structure needs.

Steel Reinforcement

Mesh, bar or a combination — specified for the load and checked before the pour goes in.

Excavation & Sub-base Prep

Excavated to depth, spoil removed, sub-base laid and compacted — the groundwork that stops movement and cracking over time.

How Your Slab Gets Built

Three clear steps, managed by one team, from the first measure to handover.

1

Set-out & Prep

We confirm dimensions from your shed kit plans or builder, mark out the pad, excavate to the right depth, and lay and compact the sub-base. Hold-down and anchor locations are set out before formwork goes in.

2

Form & Reinforce

Formwork is set to level and to the correct falls. Edge thickenings or rebates are formed where required. Steel reinforcement — mesh, bar or both — is placed and checked before we call the concrete.

3

Pour & Finish

Concrete is poured, screeded and finished to a smooth, level surface. We give you a clear timeframe for when the slab is ready for your frame installation, and we tidy the site before we leave.

What a Shed or Garage Slab Costs

Every Slab Is Quoted on Its Own Details

  • Slab area and shape
  • Thickness and reinforcement specification
  • Site access and ground conditions
  • Excavation and sub-base preparation required
  • Edge thickenings or rebates needed
  • Drainage and fall requirements

Rather than publish a flat rate that may not match your job, we price each slab on its specific requirements — so the number you receive is the number you pay. Send us your site details and kit plans and we will have a fixed-price quote back to you within 24 hours.

Shed & Garage Slab Questions Answered

The right thickness depends on what the slab needs to carry. A standard residential shed slab is typically 100 mm, while a garage slab designed to carry vehicles is usually thicker — often 100–125 mm or more depending on loads and ground conditions. We assess your site and the intended use, and specify the correct thickness before we quote.
Yes. We set out the slab to match your shed kit's bolt-down or hold-down point locations so the frame lines up correctly on the finished pad. We work from your kit's engineering drawings or anchor plans to make sure everything is in the right place before the concrete is poured.
Yes. Many shed kits require a rebate — a recessed edge so the shed wall sits flush with the slab face — and we form these as part of the job. We also form edge thickenings where specified by the engineer or required by the kit, providing the bearing capacity the structure needs.
Yes. We reinforce every shed, garage and carport slab with the correct steel — whether that is mesh, bar or a combination, depending on the engineering specification and the loads the slab needs to handle. Reinforcement goes in before the pour and is checked as part of our process.
Yes. We handle the full preparation — excavating to the correct depth, removing spoil, and laying a compacted sub-base to give the slab a stable, even foundation. Proper sub-base prep is what prevents cracking and movement over time, and it is included in every job we quote.
Concrete needs time to gain strength before it can carry load. As a general guide, most shed and garage slabs are ready for frame installation after 7–14 days, depending on conditions and the engineer's requirements. Concrete reaches its design strength at around 28 days. We give you a clear timeframe when we hand over the job.
