Project Overview

Concrete Slabs Sunshine Coast

A Sunshine Coast Concrete Slabs plan should start with load, ground conditions, reinforcement, service penetrations, finished height and the way the slab will be used after curing.

Prepare and pour fit-for-purpose slabs for outdoor structures, utility areas and residential projects.

A solid concrete slab is the foundation for almost every structure, from garages and sheds to full residential builds. Our concrete slabs Sunshine Coast team delivers properly reinforced, level slabs built to handle the load and conditions they're designed for, whether it's a small backyard project or a larger construction base.

Every slab starts with correct site preparation — compaction, formwork, and reinforcement — because a slab is only as good as what's underneath it. We work closely with builders, tradespeople, and homeowners to make sure specifications are met before a single truck of concrete arrives on site.

From driveways and sheds to full building foundations, our team handles slabs of all sizes with consistent quality and attention to detail. When you need a slab that's built to last, our team delivers the reliability your project depends on.

Plan The Work

Planning Concrete Slabs on the Sunshine Coast

Slab thickness, reinforcement, edge design and levels depend on the intended load and structure. Confirming service locations and the building specification before the pour helps avoid expensive changes.

Intended use and structural specification

Excavation, base and reinforcement

Concrete project preparation and placement

Set-downs, rebates and service penetrations

Finish, levels and curing access

Concrete slabs on the Sunshine Coast should be specified around load, ground conditions, reinforcement, control joints, finished level and future use.

A Practical Result

Concrete Slabs Sunshine Coast: What To Expect

A properly poured concrete slab forms the foundation for sheds, garages, extensions and other structures, so getting the preparation right matters from the outset. Expect adequate excavation, base compaction, reinforcement and control joints to prevent cracking and uneven settling, particularly given the reactive clay soils found through the Sunshine Coast hinterland and the summer wet that swells them. Slab thickness and mix design should be matched to intended use, whether that's a lightweight shed or a structure with ongoing vehicle access.

Correct falls are also essential to direct water away from foundations and nearby structures, reducing the risk of pooling or moisture issues over time. A well-prepared slab avoids costly problems down the track, including cracking and subsidence.

Local Conditions

The Importance of Concrete Slabs for Your Sunshine Coast Property

A properly constructed concrete slab forms the foundation for sheds, garages, extensions and other structures, making correct preparation essential from the outset. This includes adequate excavation, base compaction, reinforcement and control joints to prevent cracking and uneven settling over time. The right slab thickness and mix design depend on the intended use, whether that's supporting a lightweight shed or a heavier structure with ongoing vehicle access.

A well-poured slab also considers drainage and fall to prevent water pooling against foundations or nearby structures. Getting these fundamentals right from the start avoids costly issues down the track, including cracking, subsidence or moisture problems. Concrete slabs are a long-term investment, so proper preparation and curing time make a significant difference to durability. A site assessment will help determine the right specifications for your particular slab and its intended purpose.

Slab Thickness

How Thick Should Concrete Slabs Be?

Slab thickness depends on what the concrete needs to support. A standard residential driveway typically requires a minimum of 100mm, reinforced with SL72 mesh, while areas carrying heavier vehicles, trailers or trucks often call for 125-150mm with heavier reinforcement. Shed and garage slabs are generally poured at 100-125mm, depending on the size of the structure and whether machinery or heavier storage loads are involved.

The Sunshine Coast's variable soils, from coastal sand to reactive hinterland clay, combined with the wet summer and drier winter cycle, produce more ground movement than most homeowners expect, making adequate thickness and reinforcement particularly important to prevent cracking. Base preparation, including compaction and a suitable sub-base, also plays a major role in slab performance regardless of thickness.

Common Applications

Where to Use Concrete Slabs

Concrete slabs suit a wide range of applications beyond driveways, including shed and garage foundations, carports, workshops, alfresco areas and equipment pads. They're also commonly used as a base for water tanks, air conditioning units and outdoor kitchens, where a stable, level surface is essential. In garden and side-access areas, slabs provide a durable footing for storage sheds or bin enclosures that need to handle moisture and occasional vehicle movement.

On larger Sunshine Coast blocks, slabs are often used for boat, trailer or caravan parking bays, given their ability to handle sustained weight without shifting. Commercial and acreage properties may also require slabs for machinery pads or loading areas. Each application has different thickness, reinforcement and drainage requirements depending on the load and exposure involved.
