Carport Slabs & Covered Parking Solutions
We build carport slabs that give your vehicles proper protection without the full garage structure. Our carport floors use the same 100-125mm thickness and F72 reinforcement as enclosed garages – your ute, car, or boat sits on a surface that handles the weight without settling or cracking over time. The difference is flexibility: open carports for quick access and ventilation, partially enclosed options for weather protection on prevailing wind sides, or fully roofed configurations that keep vehicles dry year-round.
We design carport slabs to integrate seamlessly with your existing driveway, creating a unified concrete surface that looks intentional and professional. For Newcastle properties with limited space, a well-positioned carport slab adds vehicle protection without the cost and footprint of a full garage. We include proper drainage falls, anchor points for roofing posts, and optional epoxy coatings that resist oil stains and make cleaning simple. The result is practical vehicle storage that adds value to your property.
Why Newcastle Homeowners Choose Our Garage Slabs
Your garage floor carries more weight than most concrete around your property – literally. We build garage slabs with the proper 100-125mm thickness and F72 reinforcing mesh minimum, ensuring your slab handles vehicle loads without cracking or settling over time. This isn’t just any concrete pour; it’s engineered specifically for automotive weight distribution and daily traffic patterns.
Our garage floors deliver smooth, level finishes that make parking and vehicle movement effortless. We incorporate subtle drainage falls toward garage doors when needed, preventing water accumulation while maintaining the level surface your vehicles require. Oil and chemical resistance is built into our specifications – your garage floor withstands automotive fluids, workshop chemicals, and cleaning products without deterioration.
Moisture protection sits at the foundation of every garage slab we construct. Proper vapour barriers and correct thickness prevent rising damp that damages stored items and creates musty conditions. A quality garage slab increases your property’s functionality and market value, transforming unusable space into protected vehicle storage, workshop area, or versatile home extension potential.

Technical Standards: All our Newcastle garage slabs use F72 reinforcing mesh as a minimum, preventing stress fractures under vehicle load points. We include 1:100 drainage fall toward garage doors to stop water pooling, thickened edges (300mm depth) where walls need support, and control joints every 3-4 metres to manage concrete movement and prevent random cracking.
Newcastle-Specific Considerations: We account for sloping blocks common across Lake Macquarie and Maitland properties, integrate slabs seamlessly with existing driveways, plan proper water runoff for coastal conditions, ensure smooth door threshold transitions, and handle council approvals for larger structures. Termite protection is included where required in bushland areas.
Single, Double & Triple Garage Slab Options
We build garage slabs to match your vehicle storage needs across Newcastle properties. Single garage slabs (typically 3m x 6m) suit compact blocks or single-car households, providing enough space for one vehicle plus basic storage along the walls. Double garage configurations (standard 6m x 6m) accommodate two vehicles comfortably, with room for workshop benches or storage systems down one side – the most popular option for family homes.
Triple garages and larger custom sizes handle multiple vehicles, trailers, boats, or dedicated workshop areas. We’ve constructed garage floors up to 12m wide for car enthusiasts and tradies needing secure vehicle storage plus workspace. Each size uses proper thickness specifications – 100mm minimum for single garages, 125mm recommended for doubles and triples where heavier vehicles or equipment create concentrated loads.
Our Newcastle garage slabs integrate with your property layout, whether attached to the house with direct internal access or detached structures positioned for driveway flow and site conditions.
Oil-Resistant Garage Floor Finishes & Coatings
Standard concrete absorbs oil, petrol, and automotive fluids – creating permanent stains that look terrible and become slippery hazards. We offer garage floor finishes that resist these issues from day one. Our smooth trowel finish provides a dense, sealed surface that makes basic spill cleanup straightforward with a mop or hose, but for serious protection, we recommend epoxy coating upgrades.
Epoxy-coated garage floors create a chemical-resistant barrier that stops oil penetration completely. Spills sit on the surface instead of soaking in – you wipe them up without staining the concrete underneath. These coatings come in various colours (grey beingthe most popular for hiding dirt), add a professional workshop appearance, and make the entire garage floor easier to sweep and maintain.
Polished concrete options deliver similar oil resistance through mechanical densification, creating a hard surface that resists staining while providing a modern, reflective finish. Both approaches transform your Newcastle garage floor from a maintenance problem into a practical, long-lasting surface that handles daily vehicle use without deteriorating or looking shabby over time.
Garage Slabs for Sloping Blocks & Challenging Sites
Newcastle properties often sit on sloping terrain – particularly around Charlestown, Kotara, and Lake Macquarie hillside suburbs. We handle these challenging sites regularly, delivering level garage floors that integrate properly with sloping driveways and uneven ground.
Cut and Fill Solutions: We excavate into the slope where needed, creating a level platform for your garage slab while managing the cut material across your site. This approach minimises retaining wall costs while achieving the proper foundation depth.
Stepped Garage Entries: For steep driveways, we can step the garage slab slightly above ground level, preventing water from running into the garage during heavy Newcastle rain while maintaining reasonable vehicle entry angles.
Retaining Wall Integration: Where significant level differences exist, we coordinate with retaining wall construction to create stable, properly drained garage platforms that won’t shift or settle over time.
Drainage Management: Sloping blocks require careful water management. We install proper stormwater drainage, prevent runoff from entering the garage, and ensure the slab itself directs water away from the structure. Our Newcastle experience means we anticipate coastal property drainage challenges before they become problems.
Connecting Your Garage Slab to Existing Driveways
Joining a new garage slab to your existing driveway requires precise level matching – you need smooth vehicle entry without bumps, lips, or awkward transitions that scrape low vehicles or create trip hazards. We measure your current driveway height and grade the garage slab to match exactly, creating a seamless connection that looks intentional rather than like an obvious addition.
For driveways poured years ago, we account for settlement and movement that may have occurred over time. If your existing concrete has dropped slightly, we adjust the garage slab transition to compensate, preventing water pooling at the join point during Newcastle’s heavy rain periods.
The joint itself uses proper control joint techniques – we create a straight, clean line between old and new concrete that manages expansion without cracking. Where driveways show weathering or discolouration, we can extend decorative finishes or coatings across both surfaces, creating visual unity between the garage floor and approach. The result is a garage slab that integrates naturally with your property’s existing concrete work, not an obvious patch job that detracts from appearance.
Preventing Cracks in Your Garage Slab
Cracks in garage floors aren’t inevitable – they’re the result of poor specifications or shortcuts during construction. We prevent cracking through proper engineering from the start, not by fixing problems after they appear. Our Newcastle garage slabs use techniques proven to handle vehicle loads and ground movement without deteriorating.
Crack Prevention Methods:
- F72 Reinforcing Mesh: Steel reinforcement throughout the slab distributes loads and prevents stress fractures at concentrated pressure points
- Control Joints: Strategic cuts every 3-4 metres guide where concrete can move, preventing random cracking across the surface
- Proper Base Preparation: Compacted roadbase creates stable support, eliminating settlement cracks from shifting ground underneath
- Adequate Thickness: 100-125mm depth prevents flexing under vehicle weight that causes surface cracking over time
- Quality Concrete Mix: We use specifications designed for external slabs, not general-purpose mixes that aren’t suited to garage loads
The biggest crack we see across Newcastle is garage slabs poured too thin – 75mm slabs might save a few hundred dollars initially, but they crack within months under vehicle traffic. Our 100-125mm specifications cost slightly more upfront but deliver decades of crack-free performance, protecting your investment and avoiding expensive replacement down the track.
Frequently Asked Questions
We recommend 100mm minimum for single garages and 125mm for double or triple configurations. This thickness handles vehicle weight without cracking. Thinner slabs might save money initially but they crack quickly under load, requiring expensive replacement.
Yes, F72 steel mesh reinforcement is essential for garage slabs. The mesh distributes vehicle loads across the concrete, preventing stress fractures at wheel positions. Without reinforcement, cracks appear within months of use, particularly where heavy vehicles park regularly.
Wait a minimum of 7 days before driving on your new garage floor. Concrete reaches adequate strength after a week, though full curing takes 28 days. Driving too early causes surface damage and weakens the slab structure, compromising long-term durability.
Absolutely. We measure your current driveway height and grade the garage slab to create a seamless vehicle entry without bumps or lips. The joint uses proper control joint techniques that manage expansion without cracking over time.
Yes, we include a 1:100 fall toward the garage door. This prevents water pooling inside after washing vehicles or during Newcastle’s heavy rain. Without proper drainage, water sits on the floor, creating slip hazards and moisture problems.
