4 Benefits of Concrete Slabs
Durability
Concrete slabs are strong and long-lasting, able to withstand heavy loads and wear without cracking or warping, making them ideal for both residential and commercial foundations.
Fast Installation
Concrete slabs can be poured and set relatively quickly, allowing for a faster construction timeline compared to more complex foundation systems.
Versatility
If you’re building a garage or shed with concrete floor, concrete slabs can be tailored to suit various types of structures and designs.
Pest Resistance
Concrete slabs provide an effective barrier against pests, helping to protect your structure from termites, rodents, and other intruders. For example, if you use a concrete foundation for a shed, it blocks pests from gaining access into your structure.

Northern Beaches Concrete Slab Installation FAQs
What kind of concrete slabs do you build?
We provide concrete slabs of all sizes, tailored to fit any type of structure you’re planning—whether it’s a shed or carport. Each slab is designed for durability and strength, ensuring it supports your project perfectly. Our concrete slabs are ideal for a variety of applications, including:
- Shed slabs
- Carport or garage slabs
- Extensions
- Granny flats/bungalows
- Slabs for parking a caravan
Whatever your needs, we guarantee a premium-quality slab built to last.
Is it necessary to have a concrete slab for a shed?
Yes, a solid concrete base for a shed is essential to make it a durable, long-lasting structure. It provides the foundation that supports the entire structure, ensuring stability and resistance to shifting or sinking. The slab’s thickness depends on what you plan to store in the shed, and larger sheds for storing vehicles or heavy machinery require thick reinforced concrete for added strength. Without a proper foundation, your shed will lack durability and may suffer from structural issues over time.
What concrete finishes are available for slabs?
While standard plain concrete is commonly used for slabs that are not highly visible, we also offer decorative finishes for exposed areas like carports. Our range of concrete finishes includes:
- Plain concrete – Ideal for hidden or utilitarian surfaces.
- Coloured concrete – Adds a splash of colour to your outdoor space, perfect for enhancing your property’s look.
- Exposed aggregate concrete – A decorative option that reveals the natural stones within the concrete, providing a stylish, textured finish perfect for driveway concreting or carports.
These finishes allow you to customise the appearance of your slab to suit your space.
How thick should a concrete slab be?
The required thickness of a concrete slab depends on its intended use. If you’re laying a concrete pad for a shed or other lightweight structures like a patio, a typical slab should be around 100mm thick. However, if you’re constructing a garage, driveway, or commercial structure that needs to support heavier loads, a thicker slab—usually 150mm or more—may be necessary. The soil conditions and the weight of the structure or vehicles also influence the slab’s thickness. We’ll assess your project’s specific requirements to ensure the right slab thickness for long-lasting durability.
How long does it take for a concrete slab to cure?
Concrete slabs begin to set within 24-48 hours, allowing for light foot traffic during that time. However, full curing takes up to 28 days, during which the concrete continues to gain strength. For heavy use, like parking vehicles on a driveway or installing large structures, it’s best to wait the full curing period. Proper curing ensures your slab reaches maximum strength and durability, reducing the risk of cracking or damage.
Can concrete slabs be installed on uneven ground?
Yes, we can install concrete slabs on uneven ground by properly preparing and levelling the site beforehand. This involves grading or compacting the soil and potentially using additional formwork to create a stable base. Proper site preparation is critical to ensure the slab remains even, stable, and crack-resistant, regardless of the original terrain. Whether your site has a slope or uneven areas, we’ll ensure the slab is poured on a solid, level foundation.
How does weather in the Northern Beaches affect concrete slabs?
The coastal weather in the Northern Beaches, including high humidity, salt air, and frequent rain, can impact concrete slabs if they’re not installed or maintained properly. Salt can accelerate wear and corrosion, while moisture may seep into unsealed concrete, causing cracks or damage over time. To combat these effects, we use high-quality materials and proper sealing techniques to protect your slab from the elements. Regular maintenance, such as resealing, also helps to ensure your slab withstands the coastal climate for years to come.
