Types of Garage Slabs We Build in Townsville
Every property’s different, and so’s every garage project. Over the years we’ve done just about every configuration you can think of across Townsville suburbs.
New Home Garage Slabs are probably our most common job. You’re building from scratch, which means we can get everything right from the ground up – proper soil prep, correct thickness, reinforcement that matches your specific needs.
Detached Garage Foundations are popular with folks who want their workshop or storage separate from the house. These need special attention because there’s no existing structure to tie into, so we make sure the edge beams and footings are engineered properly for standalone strength.
Double and Triple Garage Slabs are standard requests from boat owners, caravan enthusiasts, and anyone with a few vehicles. The bigger the slab, the more critical proper reinforcement becomes. We’re talking about supporting multiple tonnes of vehicles and equipment long-term.
Garage Extensions and Additions come up when you’ve outgrown your single garage. The tricky part here is matching the new slab to your existing one – getting the levels right, making sure there’s no differential settlement between old and new concrete.
Carport to Garage Conversions mean we’re working with an existing slab that might not have been built to garage standards. Sometimes the existing slab’s fine, other times we’re recommending a complete replacement because it won’t cut it once you enclose the space and park vehicles inside permanently.
Workshop Garage Combinations need extra consideration for heavy equipment, tool storage, and sometimes machinery that creates vibration or point loads that standard residential slabs weren’t designed for.
Whatever type you need, we’ll measure up, assess your specific site conditions, and spec the right solution for your Townsville property.
Getting Your Garage Slab Size and Design Right
Size matters when it comes to garage slabs, and we see plenty of people regret going too small to save a few bucks.
Standard single garages start at 3m x 5.5m – that’s barely enough for a modern vehicle with some storage. Most people wish they’d gone bigger. Add an extra meter of length if you want any meaningful storage space or a workbench at the back.
Standard double garages are 5.5m x 5.5m, which fits two vehicles side-by-side with minimal room to spare. If you’ve got bigger vehicles, a boat, or want workshop space, you’re looking at 6m x 6m minimum.
Extra length for storage is the most common addition we recommend. Adding 1-2 meters to the back of your garage costs less than you’d think during construction, but gives you space for shelving, tools, and all that gear that’d otherwise clutter your yard.
Door clearance and approach angles need careful planning. You don’t want to pour a perfect slab then realise your 4WD scrapes the driveway every time you enter because someone didn’t think about the angle.
Internal access doors are easier to plan before the pour than after. We sleeve in the footing where you’ll want doorways into the house or yard.
Service penetrations for power, water, or drainage should be planned now. Cutting through a finished slab later is expensive and weakens the structure.
Vehicle turning radius matters if you’re tight on space. We’ve seen garages where you can barely get in and out because nobody thought about the turning circle.
Plan properly now, thank yourself later.

How We Install Your Garage Slab Start to Finish
Here’s exactly what happens when we turn up to pour your garage slab, because understanding the process helps you spot quality work versus cowboys cutting corners.
Site excavation and levelling comes first. We’re digging out to the depth we need, which is usually 150-200mm below your finished floor level. This gives us room for the base, moisture barrier, and concrete thickness.
Base preparation and compaction is where average concreters lose the plot. We bring in crushed rock or roadbase, spread it evenly, and compact it properly with a plate compactor. Then we test it. If it’s not rock-solid, we’re doing it again. Your slab’s only as good as what’s underneath it.
Termite barrier installation is mandatory in Queensland. We lay the physical barrier or apply chemical treatment before anything else goes down. Skip this step and you’re inviting problems.
Edge beam formwork gets set up next, creating the perimeter where your walls will sit. These forms hold everything in place and create those deeper edge beams that support your structure.
Steel mesh placement happens the day of the pour. We lift the mesh onto plastic chairs so it sits in the middle third of the concrete thickness – that’s where it does its job best.
Concrete pour and finishing is where experience shows. We pour, spread, screed it level, then finish the surface. Smooth trowel or broom finish depending on what you’ve chosen.
Curing takes 7 days minimum before you park vehicles on it. We wet-cure or apply curing compound to stop it drying too fast in Townsville’s heat.
Frequently Asked Questions About Garage Slabs in Townsville
Minimum 7 days for light vehicles, but we recommend 14 days if you can wait. For heavy vehicles, trailers, or equipment, give it the full 28 days to reach maximum strength. Park too early and you risk surface damage and cracking that’ll never properly heal.
Usually yes if you’re building a new garage structure. The slab itself isn’t the issue – it’s the garage building that requires approval. Replacing an existing slab on the same footprint typically doesn’t need approval, but check with Townsville City Council first. We can advise based on your specific situation.
Poor soil preparation is number one by far. Second is insufficient reinforcement. Third is inadequate thickness for the load. Townsville’s reactive clay soils will find every weakness in a poorly built slab. That’s why proper engineering and construction matter so much here.
Yes, but there’s always going to be some colour difference between old and new concrete. We get the levels perfect and tie the reinforcement together properly, but concrete ages and the new pour will look newer. After a few months of weathering, the difference becomes less noticeable.
Standard single garage slabs typically run $3,000-$5,000 depending on site access, soil conditions, and specifications. Double garages $6,000-$10,000. These are ballpark figures – every site’s different. We provide free quotes with no obligation.
