Concrete Garage Slabs
A hard-wearing floor built to take vehicles for good.
Garage Slabs in Perth
A garage floor takes vehicle loads, oil, tools and daily traffic. We pour dense, correctly reinforced garage slabs with the right falls and finish so they stay sound and easy to clean for decades.
The garage slab is one of the hardest-working surfaces on a property. It carries the weight of vehicles, resists oil and chemical spills, and takes constant foot and trolley traffic.
That means it has to be poured dense, reinforced properly and finished smooth and flat, with a slight fall so any water or wash runs to the door rather than pooling inside.

What a Good Garage Slab Needs
- Adequate thickness and reinforcement for vehicle loads
- A smooth, dense finish that resists oil and staining
- A slight fall to the door so water and wash drain out
- Clean, square edges for the walls and door track
- Control joints to manage shrinkage cracking
- A properly compacted base so the slab does not settle
Thickness and Reinforcement
A residential garage slab is typically poured thicker and with heavier reinforcement than a standard path or patio because of the vehicle loads. The exact specification depends on the vehicles and any workshop use.
| Garage Use | Slab Thickness | Reinforcement |
|---|---|---|
| Standard 1 to 2 car residential garage | 100mm minimum | SL82 mesh |
| Garage with heavy 4WD or trade vehicles | 125mm | SL82 mesh or N12 bar |
| Workshop with vehicle hoist | 150mm with thickened hoist pads | N12 or N16 bar, engineer's specification |
| Commercial or heavy workshop | 150mm to 200mm, engineer's design | Structural reinforcement as specified |
Plan for what the garage really does
A daily-driver garage and a home workshop with a hoist have different slab needs. Tell us how you will use it and we will pour accordingly. Specifying a hoist pad later into an under-designed slab is expensive.
Finishes for a Garage Floor
Most garage slabs get a smooth trowel finish for easy cleaning, and many owners seal or coat them later for extra durability and a tidier look.
| Finish | Benefit | Best For |
|---|---|---|
| Smooth trowel | Easy to sweep and clean, standard choice | All residential garages as the base finish |
| Lightly broom finished | More grip underfoot, slightly textured | Garages used as workshops where grip helps |
| Sealed | Resists oil and dust, much easier to wipe down | Garages where appearance and cleanliness matter |
| Epoxy coated (applied later) | Hard-wearing, chemical resistant, showroom look | Home workshops, show garages, commercial spaces |
Frequently Asked Questions
Common questions about garage slabs in Perth.
A residential garage slab is typically poured thicker and more heavily reinforced than a path, because it carries vehicle loads. The exact spec depends on the vehicles and any workshop use, which we match at the quote.
A slight fall toward the door is ideal so any water, wash or spill drains out rather than sitting on the floor. We set that gentle fall as part of finishing the slab.
Yes. A properly finished and cured garage slab is a good base for sealing or an epoxy-style coating down the track if you want a harder-wearing, showroom finish. Pouring it well now keeps that option open.
Yes. We pour garage slabs for new builds, workshop conversions and rebuilds, coordinating the set-out and levels with your builder or garage supplier.
Yes. A floor drain or channel can be incorporated into the pour, either in the centre of the garage or at the door threshold. It needs to be planned before the pour so the drain position and falls all work together.
Preparation and pouring a standard residential garage slab typically takes one day. Add the curing time and the garage is usually ready to build on within 7 days, with full strength at 28 days.
Yes. Access is assessed at the quote. Where a concrete truck cannot reach, we use a pump or a conveyor. Tight access is a practical challenge we solve regularly, not a reason to decline the job.
The requirements are similar but a garage slab attached to a house often needs to integrate with the house slab or footings and comply with building permit conditions. A detached shed slab is more straightforward. We assess what applies at the quote.
