Plain 20–25 MPa Concrete in Wollongong
Get a Free EstimateNatural Grey Concrete for Wollongong Homes
Not every job needs colour, stamping or exposed stones. Sometimes the smartest choice is a well-placed slab of natural grey concrete, poured on a solid base and finished neatly. Our plain concrete in Wollongong uses standard 20 MPa and 25 MPa mixes, the everyday workhorses of residential concreting, with no oxide added, so you get a clean, honest grey surface at a price that makes sense.
Plain concrete still deserves proper workmanship. The ground is prepared and compacted, reinforcement goes in where the job calls for it, falls are set so heavy rain runs away from the house, and control joints are placed to manage shrinkage. Choose a broom, float or trowel finish to suit how the area will be used, and add a sealer if you like. Tell us what you're planning and we'll recommend the right mix and finish.
Plain Concrete Jobs We Pour Across Wollongong
Everyday Residential Driveways
For a standard family driveway carrying cars and the odd ute, a properly designed 25 MPa mix with mesh and good joints is a common, cost-effective choice. A broom finish gives grip on the sloping blocks under the escarpment, and the plain grey look suits fibro cottages and new builds alike.
Footpaths and Garden Paths
Side paths to the clothesline, a front path to the letterbox or a link between the house and the shed rarely need anything fancier than plain concrete. We set the falls so water runs off into the garden or a drain rather than pooling against your walls.
Patios and Alfresco Areas
A smooth trowelled or lightly broomed grey patio gives you a clean base for outdoor furniture, a barbecue or a future roof. It also takes tiles, pavers or a sealer later if you want to dress it up down the track.
Garage and Shed Slabs
Garden sheds, single garages and small workshops are typical jobs for 20–25 MPa concrete, provided the thickness and reinforcement match the load. Hold-down bolts are set in place and a gentle fall toward the door makes hosing out easy.
Steps, Landings and Kerbing
Front steps, back-door landings, garden edging and kerbing are all well suited to a plain mix. We form consistent risers, add a non-slip finish on treads and leave edges crisp so mowers and whipper snippers have a clean line to follow.
Pool Surrounds, Paving Bases and Hardstands
Plain concrete makes a reliable base under pavers or tiles around the pool, and a practical light-duty hardstand for bins, a trailer or a garden tank. Where salt air, chlorine or heavier loads come into play, we'll talk through whether a stronger grade makes more sense.
Three Easy Ways to Start Your Plain Concrete Project
Plain grey concrete is the backbone of most backyards and front yards around the Illawarra, from concrete driveways and footpaths to garden paths, patios and shed slabs. Getting a price is simple.
- Tell us the size and use: Rough measurements and what the area will carry, whether that's foot traffic, a family car or a garden shed, are enough for us to suggest a grade, thickness and finish.
- Share any plans: If an engineer or builder has specified a concrete grade, slab thickness or reinforcement, mention it in the form and we'll price exactly to those details.
- Book a site visit: We'll check levels, soil, drainage and truck or pump access, and point out anything like a steep slope or soft ground that affects the job.
We also pour plain concrete for steps and landings, kerbing and edging and bases around a pool deck. If a job involves heavier loads, structural work or harsh coastal exposure, we may recommend 32 MPa structural concrete instead, depending on what your engineer or the standards require.
Why Wollongong Homeowners Trust Us With Plain Concrete
The Right Grade for the Job
We don't upsell a premium mix where a 20 or 25 MPa pour will do the work, and we won't cut corners where your engineer, the standards or the site call for something stronger. You get a straight answer on which grade fits.
Preparation Done Properly
Plain concrete is only as good as what sits under it. We dig out soft spots, compact a crushed-rock base in layers and deal with reactive clay or wet coastal sand before any concrete arrives.
Mesh and Joints Where They Count
Driveways, slabs and wider paths get reinforcement chaired at the correct cover. Control joints are tooled or saw-cut at sensible spacings so any shrinkage cracking follows a neat line instead of wandering across the surface.
Falls Built for Illawarra Downpours
When an East Coast Low or a summer storm rolls in, water needs somewhere to go. Every surface is set with a fall away from the house and toward a garden bed, grate or the street.
Curing That Suits the Season
Hot summer sun and a stiff nor'easter can dry the top too fast, while cold winter mornings slow the set. We plan pour times around the forecast and keep the surface protected while it gains strength.
Clear, Itemised Quotes
Excavation, base, formwork, mesh, concrete and finishing are listed separately, so you can see exactly where the money goes and compare quotes like for like.

Plain Concrete Questions Answered
What Wollongong homeowners most often ask about 20–25 MPa concrete, from what the numbers mean to finishes, sealing and when a stronger grade is needed.
MPa stands for megapascals, the unit used to describe concrete's compressive strength. A 20 MPa mix (often written N20) is designed to reach a characteristic strength of 20 MPa at 28 days, and a 25 MPa mix (N25) reaches 25 MPa. In practical terms, both are normal-class mixes used widely for residential flatwork like paths, patios, shed slabs and driveways. The number you need depends on the job, the loads and any engineering or standards requirements for your site.
For most homes, yes. A typical driveway for cars and light utes is commonly poured in 25 MPa concrete with mesh, a well-compacted base and properly spaced joints. If you regularly park a heavy truck, a caravan or machinery on it, or the engineer has specified a higher grade, we'll step up the strength and thickness to suit. The base and reinforcement matter just as much as the mix.
A higher grade is often worth considering for heavier vehicle loads, structural elements such as footings, suspended slabs or retaining walls, and some sites close to the ocean where salt exposure is a concern. The National Construction Code, the relevant Australian Standards or your engineer may set a minimum grade for certain work, so check your plans. If you're unsure, we can talk it through at the site visit.
A broom finish is the go-to for driveways, paths, steps and pool surrounds because it gives good grip when wet, which matters on Wollongong's sloping blocks and in rainy weather. A wood or steel float finish suits areas that will be tiled or paved later. A smooth steel trowel finish is popular in garages and sheds where you want an easy surface to sweep, though it can be slippery outdoors when wet.
Sealing is optional but can be worthwhile. A good sealer helps resist oil and food stains, makes cleaning easier and can slow the build-up of moss and mould on shaded areas under the escarpment. On the coastal strip it adds a layer of protection against salt spray. Most sealers need reapplying every few years, and we'll recommend one that keeps a non-slip finish on outdoor surfaces.
