Bathurst Concreting
Imagine a premium slab that is hardened and dense, poured and cured properly so that it doesn’t break down even after a decade of use? At Bathurst Concreting, we provide fresh concrete slabs for homeowners and businesses in Bathurst, NSW and the surrounding region. We guarantee elite jobs within a 60 km radius from Bathurst, and can drive out to Bathurst and Lithgow to start building projects. From local families to retail shop owners and property managers, we work with anyone looking to get a high-end concrete slab installed that is durable for many years to come.
To ensure we deliver a deluxe slab we promise for your property, we handle everything from site preparation and formwork to the pouring and curing process ourselves. Our trained crew uses a precise mix of concrete that isn’t too diluted nor too dry to be able to cure perfectly in Bathurst’s sun. This results in a smooth, hard concrete surface that will be durable and last you multiple decades, perfectly fit for your home or business to be built on top. Our team also ensures that the slab fits the architectural measurements precisely so that there are no additional gaps in spacing when the rest of the construction takes place over your slab.
Why Use Our Professional Slab Installation Services
Unlike small slabs that can be done poorly and are inexpensive to replace or get done, larger slabs cannot hold any margin for error. Small projects like a garden step can be handled as a DIY project. However, a larger slab requires experience and expertise to get foundations prepared, your site excavated, and proper pouring and curing to achieve a solid concrete strength.
There are just too many variables to rely on to get it right. Once a slab needs to actually carry structural load, it needs to meet certain strength requirements that would fail very quickly without the right process in place. Getting an inexperienced or cheap contractor would lead towards actual issues and cracking or weakening of your concrete very quickly. Bathurst Concreting handles jobs of all sizes and ensures they meet what your project actually calls for.
Concrete Slab Installation Errors
Poor Formwork
Before any concrete gets poured out, timber or steel frames are placed vertically throughout the area that form the frame of your entire concrete slab. This frame ends up holding your concrete in shape and helps it to keep it level. When formwork is poorly done, it isn’t level or square, so your slab doesn’t have the right guidelines and can end up uneven and out of shape, not aligning to the specifications initially set for it. Our team properly ensures that all corners are square and the formwork’s frame sits level so that your slab will end up in shape once cured.
Why Too Much Water Ruins Concrete
Mixing concrete can usually seem pretty straightforward; however, the water ratio does matter more than people realise. Too much water can weaken your mix and reduce the final strength of your slab. This ultimately makes it more likely to crack over time. Inexperienced contractors tend to fall into this, as a more watery concrete mix would be easier to pour, but the slab itself won’t hold up well under the strong load and can easily break down. Our concreters in Bathurst, NSW use the right water ratio in every mix we pour, tailored to what we’ve seen cures well in the local climate. We usually start it off on the slightly drier side but continue to add water during the curing process so that it reaches maximum strength. This works much better than trying to remove moisture from an already poured out concrete mix, which is much harder to do.
Working On Poured Concrete Too Early
After we’ve poured your concrete and screeded it to remove excess concrete from the surface, there will usually be some level of water that rises up to the surface. This is called bleed water, which comes from any extra mixing water in your concrete mix. We want to allow this water to evaporate in Bathurst’s sun before doing any work on the surface. Working the concrete surface too early traps water in your concrete and weakens the layer on top, which causes it to flake and deteriorate quickly compared to the rest of the slab. Our team ensure the water is fully evaporated before any surface finishing begins, as it keeps the concrete smooth. If there is too much bleed water from a highly diluted concrete mix, we use a squeegee to drag off excess water off your slab.
If you’re planning to get a concrete slab poured out for your site, whether a home, warehouse or store, get a concrete specialist who has experience doing these jobs on a regular basis.

Concrete Slab Installation Process
When we start the job for you, we follow a precise process that ensures that our slabs are poured and cured well into a tough structure that can serve you for multiple decades. We also keep them accurately sized to meet the detailed building specifications. This way, our trained concrete crew can repeatedly prepare, pour, and cure concrete slabs for a wide variety of customers, whilst promising a durable concrete surface with our 15-year-warranty for structural issues.
Here’s our entire slab installation process:
1. Site Preparation and Excavation
When arriving on your site, we clear anything on the ground to be dug up. This includes vegetation and roots. We then dig down to the right depth that will account for a proper subbase and your slab's thickness. Once done, we use a plate compactor that packs the soil tightly and compresses it to form a solid shape and base for the base and slab to go on.
2. Subbase and Formwork
Once this is done, we start laying your subbase. We start this with a layer about 100 to 150 mm of crushed rock and gravel that will be sloped to help with drainage and support your concrete and spread load pressure across your surface. We then install a heavy-duty plastic sheet that blocks all moisture from rising from your ground into your slab. Next, we use timber as formwork to meet detailed measurement specifications for your slab.
3. Reinforcement and Pour
Steel rebars are now placed in a grid, elevated with some concrete lifts to keep them in the middle of your slab instead of at the bottom. This reinforcement allows for flexing in your concrete without immediate snapping when heavy vehicles drive on it. We then use a high-strength concrete mix that would be anywhere from 32 to 40 MPa for the concrete pour. We use vibrators throughout your concrete to remove any air pockets and remove any excess concrete after the pour.
4. Finishing and Curing
Finally, we use a bull float to flatten and smoothen your concrete mix, and also bring up a smooth cement cream from your concrete to the surface. We then use a power trowel to continue to flatten the surface and get the dense concrete you'd want for your surface. We do this after your concrete has cured slightly. This also removes high spots and fills low spots. We now cut control joints to allow concrete to flex throughout your concrete and apply finishes to achieve the visual look you'd want for your concrete. Once this is done, we keep your concrete consistently curing, adding water when it dries quickly in the sun so that it meets its optimal density and strength.
If you’re planning to get a new slab poured out, it’s important to get contractors who have experience doing it right consistently. The best way is to know that your concreter has a precise process in place. In our case, you get that, as well as a trained crew that has years of experience under their belts with these projects. Don’t hesitate any further. Contact us today and let’s get your architectural slab precisely installed just for you.
FAQs
How much is concrete per m² in NSW?
In regional NSW, the average cost for a professional concrete installation typically ranges from $100 to $160 per square meter.
- Plain Concrete: $100 – $120 per m²
- Reinforced Concrete: $120 – $150 per m² (Recommended)
- Decorative (Exposed Aggregate): $150 – $200+ per m²
Note: Prices in Bathurst, NSW may fluctuate slightly based on site accessibility and the distance the "ready-mix" truck has to travel from the plant.
Do concreters need a license in NSW?
Yes. In New South Wales, any person carrying out residential building work (including concreting) valued at more than $5,000 (incl. labor and materials) must hold a valid contractor license from NSW Fair Trading. Always check your contractor’s license number before signing a contract to ensure you are covered by Home Building Compensation insurance.
What is the 4-2-1 rule for concrete?
The 4-2-1 rule is a traditional ratio for mixing standard-strength concrete. It stands for:
- 4 parts Gravel (Aggregate)
- 2 parts Sand
- 1 part Cement
This ratio provides a solid balance of strength and workability. For structural slabs in New South Wales, most professionals use a pre-mixed 25MPa or 32MPa concrete from a local plant to ensure consistency against the local freeze-thaw cycles.
How much will a 20x20 concrete slab cost?
It depend if you're measure in feet or metres.
- 20ft x 20ft (~37m²): This is roughly a standard double-garage size. You can expect to pay between $4,000 and $6,000 for a reinforced slab.
- 20m x 20m (400m²): This is a massive industrial-sized slab. A professional pour of this scale would typically range from $45,000 to $65,000+, depending on the thickness and the amount of steel reinforcement required.
How high are concrete slabs?
"Height" usually refers to the thickness of the slab. Standards vary by the intended use:
- Patios/Footpaths: 75mm – 100mm thick.
- Residential Driveways/Sheds/Garages: 100mm - 150mm thick (with SL72 or SL82 mesh).
- Heavy Vehicle Industrial Slabs: Depends, but can exceed 200mm tohandle heavy machinery and poor soil conditions (Clay in Orange, NSW).
How far will a 20 kg bag of concrete go?
A standard 20 kg bag of pre-mixed concrete doesn't go very far! One 20 kg bag yields approximately 0.01 cubic meters of wet concrete.
To cover 1 m² at a standard depth of 100mm, you would need roughly 10 to 11 bags. If you are just doing a small patch or post-hole, a few bags are fine. For a full slab, ordering a truck is significantly more cost-effective. That's where our concreting services come in, to tackle larger scale jobs you've got.
