Quick Answer
Concrete in Adelaide comes in five main finishes: plain broomed concrete for practical surfaces, coloured concrete with pigment through the mix, exposed aggregate revealing decorative stone, honed concrete ground smooth and matte, and polished concrete for premium indoor floors. The right choice depends on the job the surface has to do.
Every concrete project starts with the same question: what should the surface look like and how hard does it need to work? These are the finishes we install across Adelaide and where each earns its place.
Plain (broom or float finish)
The practical workhorse: textured for grip, the most affordable option, and right for side paths, shed slabs and rear driveways where budget beats styling.
Coloured concrete
Oxide pigment through the whole mix delivers full-depth tone that cannot peel or wear off. The most popular step up from grey for patios, paths and modern frontages.
Exposed aggregate
Decorative stone through the mix, revealed by washing back the surface. Premium texture, natural colour, serious grip, and the finish of choice for front driveways.
Honed and polished
Grinding creates smooth, refined surfaces: honed for outdoor areas and pool surrounds, mechanically polished for sleek indoor floors with a light-reflective sheen.

Average Cost of Concrete in Adelaide
As a general guide, plain concrete in Adelaide is priced from $90 to $110 per square metre, with exposed aggregate starting from $145 per square metre for a base colour. Coloured and honed finishes sit between those markers, and polished indoor floors are quoted to the slab and spec. Treat all of these as orientation figures rather than quotes, because the ground under your project moves the number more than the finish on top of it.
Site preparation is the invisible variable: excavation depth, base material and compaction, access for machinery, slope, drainage and whether old concrete needs concrete removal first. That is why two identical-looking driveways can carry very different prices, and why we quote fixed numbers only after standing on the site. The same logic applies whether the project is a driveway, a patio or concrete slabs Adelaide for a shed or extension.
Concrete Maintenance and Sealing
Concrete asks very little, but what it asks matters. Clean spills promptly so oil and tannins cannot soak into the pores, wash surfaces once or twice a year, keep stormwater draining off the slab rather than pooling beside it, and respect curing times on new pours before loading them.
The single highest-value habit is sealing. A quality sealer blocks the UV fading that South Australian summers inflict on unprotected colour, stops stains soaking in permanently, and keeps decorative finishes looking freshly poured. Most surfaces want resealing every two to five years, and the water test tells you when: if water soaks in flat instead of beading, protection is gone. Our concrete sealing Adelaide service handles sealer selection, preparation and application across every finish.
Common Concrete Problems and Repairs
Cracking
Hairline shrinkage cracks are cosmetic and normal. Wide, growing or stepped cracks signal ground movement in Adelaide’s reactive clays and need cause-first professional repair.
Spalling and surface breakdown
Flaking and chipping where the top layer lets go, usually from age, water or poor original finishing. Repairable when caught early, before water accelerates it.
Sinking and lifting
Sections moving relative to each other point to base washout or compaction failure. Surface fixes cannot solve this; the ground underneath needs attention.
Staining and fading
Oil shadows, tannin marks and UV-dulled colour on unsealed surfaces. Deep cleaning helps; sealing afterwards stops the cycle repeating.
The repair path depends on the cause. Sound slabs with surface damage suit concrete repairs Adelaide or, where the whole face is tired, concrete resurfacing with a decorative overlay. Slabs with failed bases are honest replacement candidates, and because we handle earthmoving and concrete as one crew, the diagnosis you get reflects what the ground actually needs rather than what a coating salesman can sell.
