How thick should a garage slab be?

A residential garage slab in Bundaberg should be at least 100mm thick for standard vehicles, with 150mm recommended for better durability and heavier vehicles. The right thickness depends on several factors:
Standard garages: 100-125mm thickness suits regular passenger vehicles
Heavy-duty garages: 150-175mm thickness handles SUVs, utes, and light trucks
Workshop slabs: 175-200mm thickness supports heavy equipment and machinery
Reinforcement requirements: Steel mesh (SL82) or reinforcing bar increases load capacity regardless of thickness
Bundaberg’s soil conditions and climate influence slab specifications. Properties with reactive clay soils or flood exposure may require thicker slabs with additional reinforcement. A properly engineered garage slab includes correct thickness, adequate ground preparation, and appropriate reinforcement to prevent cracking and guarantee long-term performance.

Our Garage Slab Installation Process

Site Preparation and Ground Compaction: We excavate to the required depth, remove unsuitable material, and compact stable fill in layers. Proper drainage installation prevents water accumulation under your slab.
Reinforcement and Structural Integrity: Steel mesh (SL82) or reinforcing bar gets positioned according to engineering specifications. The reinforcement placement directly affects your slab’s load-bearing capacity and prevents cracking over time.
Concrete Pouring and Finishing: We use concrete mixes designed for garage applications and pour to exact thickness specifications. The levelling and screeding process creates a smooth finish for vehicle traffic and roller door operation.
Curing and Final Quality Checks: Proper curing time builds strength into your concrete slab. We verify the level across the entire surface and conduct final inspections before handover to guarantee quality.

Frequently Asked Questions About Garage Slabs
A standard single or double-garage slab takes 1-2 days from start to finish. We excavate and prepare the site on day one, then pour and finish the concrete on day two. The slab needs a minimum of 7 days of curing time before you can drive on it, with full strength reached after 28 days.
Most garage slabs require council approval as part of your overall garage construction. We can advise on the requirements for your specific property and help coordinate with your builder to meet Bundaberg Regional Council specifications.
Garage slabs need to be perfectly level for roller doors to operate properly, while driveways have a slight slope for drainage. Garage slabs also typically use thicker concrete and heavier reinforcement because vehicles sit stationary in one spot, creating concentrated weight loads.
We assess each cracked slab individually. Minor surface cracks can often be repaired with resurfacing, but slabs with major structural cracks or significant settlement usually need replacement. We provide honest recommendations based on your slab’s condition.
Garage slab costs vary based on size, thickness, reinforcement requirements, and site conditions. We provide free quotes after inspecting your site and discussing your specific needs. Contact us for accurate pricing on your project.
All concrete can develop minor hairline cracks as it cures and settles. We minimise cracking risk through proper ground preparation, adequate reinforcement, correct concrete mix, and proper curing. Our slabs are engineered to perform for decades without significant cracking.
