Professional Garage Slab Construction
A garage slab must withstand vehicle loads, weather exposure, and daily wear. Our garage slabs are engineered to handle single and double vehicle parking with proper reinforcement, drainage, and finishing. Whether you're building a new garage or need a standalone parking pad, we provide durable solutions that protect your vehicles and last for decades.
Unlike garden sheds or storage areas, garages require thicker concrete, stronger reinforcement, and proper edge beams to safely distribute vehicle loads. Our expertise ensures your garage slab meets these demanding requirements while providing a smooth, level finish for safe vehicle operation.
Single vs Double Garage Slabs
The choice between single and double garage slabs depends on your vehicle count and available space:
- Single garage slabs: Ideal for single-vehicle households or where space is limited. Compact and cost-effective, single garage slabs provide all the durability and functionality of larger installations.
- Double garage slabs: Perfect for multi-vehicle households or those needing workspace alongside parking. Double slabs offer flexibility for vehicle storage, workshops, or future expansion.
Both configurations receive the same quality construction standards and professional finishing, ensuring years of reliable performance.
Standard Garage Slab Sizes
We construct garage slabs in several standard configurations to suit most Queensland properties:
| Configuration | Dimensions (metres) | Area (sqm) | Vehicle Capacity |
|---|---|---|---|
| 3x6 (Single) | 3m wide × 6m deep | 18 sqm | 1 vehicle |
| 6x6 (Single/Double) | 6m wide × 6m deep | 36 sqm | 2 vehicles side-by-side |
| 6x7 (Double) | 6m wide × 7m deep | 42 sqm | 2 vehicles with extra depth |
Custom sizes are available. Contact us to discuss your specific requirements and parking needs.
Garage Slab Thickness and Durability
Vehicle weight demands thicker, stronger slabs than storage structures:
- 100mm thickness: The standard for all garage slabs. This thickness safely distributes vehicle loads (typically 1500-2000kg per vehicle) and resists cracking from weight and temperature variation.
- Why 100mm? Vehicles create dynamic loads that heavier concrete better resists. 100mm provides the optimal balance between cost-effectiveness and structural performance.
All our garage slabs include proper reinforcement and are constructed to Australian standards for vehicle load safety.
Edge Beams and Footing
Professional garage slabs incorporate edge beams and footings that standard storage slabs don't require:
- Edge beams: Thickened edges (typically 150-200mm) provide extra strength at the slab perimeter, preventing cracking and edge damage from vehicle traffic.
- Footings: Proper ground preparation includes compacted base layers and sometimes deeper footings in areas with poor soil conditions or high water tables.
- Reinforcement: Heavy rebar placement ensures loads distribute evenly, with special attention to wheel load paths where vehicles typically drive.
These features are standard in our garage construction and ensure long-term durability in Brisbane's variable conditions.
Surface Finish Options
The surface finish affects both appearance and safety:
- Broom finish: Provides slip resistance for safety, especially in wet weather. The textured surface helps water drain away and prevents vehicles sliding on wet concrete.
- Exposed aggregate: Decorative option with exposed stone offering attractive appearance and excellent traction. Ideal if your garage is visible from the street.
- Smooth finish: Allows for epoxy coating or paint application for sealed, low-maintenance surfaces that are easy to clean.
We recommend broom finish for most garages due to superior safety and low maintenance requirements.
Vehicle Load Considerations
Our garage slabs are engineered for typical passenger vehicles (cars, SUVs, light utes). Key considerations:
- Standard vehicles: 100mm slabs handle passenger cars (1000-1500kg each) and light SUVs with ease.
- Heavy vehicles: If you plan to park trucks, trailers, or other heavy equipment, inform us during the quote process. Thicker slabs or special reinforcement may be required.
- Concentrated loads: Vehicle jacks, tool stands, or equipment storage create concentrated loads. Proper preparation and reinforcement handle these safely.
Always discuss your vehicle types and usage patterns so we can design the slab appropriately.
Drainage and Fall Requirements
Proper drainage prevents water damage and extends slab life:
- Fall gradient: Garage slabs incorporate a slight fall (typically 1:100 to 1:50 gradient) to direct water toward edges or designated drain areas, preventing water pooling under vehicles.
- Perimeter drainage: In areas with poor natural drainage, we install perimeter French drains or gravel trenches to manage subsurface water.
- Queensland climate: Brisbane's wet season demands robust drainage. We assess rainfall patterns and site conditions to ensure effective water management.
Proper drainage maintenance protects your slab and prevents structural issues from prolonged moisture exposure.
Frequently Asked Questions
Can a garage slab handle motorbikes or trailers?
+Yes, our standard 100mm garage slabs safely handle motorbikes and light trailers. Heavy trailers or equipment requiring frequent movement may require consultation. Contact us with details about what you plan to park, and we'll confirm suitability or recommend upgrades if needed.
How long does a garage slab last?
+A properly constructed garage slab with maintenance can last 40-50 years or longer. Regular sealing (every 2-3 years), prompt repair of small cracks, and good drainage maintenance extend the slab's lifespan significantly. Our quality construction ensures decades of reliable service.
Should I paint or seal my garage slab?
+Sealing is optional but recommended. Concrete sealers protect against staining, moisture penetration, and wear, extending the slab's life and simplifying cleaning. Epoxy or polyurethane coatings provide a finished look while protecting the concrete. We can recommend suitable products during or after installation.
Do you handle small garage slab projects?
+Yes, we specialise in small to medium-sized jobs, including single-car garage slabs. Our focus on residential projects means we're equipped and experienced with typical home garage installations. Get a free quote for any size project.
