Whether you're replacing a cracked driveway, upgrading a patio, or creating a new alfresco entertaining area, choosing the right concrete contractor in Adelaide comes down to three things: correct engineering for SA soils, honest pricing, and a licensed team that stands behind its work. Opal SA Construction (BLD 317725) has built its reputation on all three across hundreds of jobs in Adelaide's northern, eastern, southern, and western suburbs.

Residential Concrete Pricing in Adelaide
Our pricing is transparent and includes everything — excavation, roadbase, moisture barrier, mesh reinforcement, concrete, finishing, control joints, curing compound, and site cleanup. There are no hidden extras.
| Service | Finish / Type | Price Range |
|---|
| Concrete Driveway | Plain grey broom | $75–$95 / m² |
| Concrete Driveway | Coloured / stencil | $95–$120 / m² |
| Concrete Driveway | Exposed aggregate | $140–$200 / m² |
| Concrete Patio / Alfresco | Broom or trowel | $75–$90 / m² |
| Pool Surrounds | Exposed aggregate R11 | $140–$200 / m² |
All prices are fully installed and include excavation, compacted roadbase, reinforcement mesh, concrete placement, finishing, control joints, curing compound, and site cleanup. For non-standard sites requiring extra excavation, removal of existing concrete, or heavy compaction work, an additional base preparation charge of $20–$50/m² applies — quoted separately before any work begins.
Why Adelaide Soil Conditions Matter for Concrete
Adelaide has some of the most reactive clay soils in Australia. Suburbs across the northern corridor (Salisbury, Gawler, Elizabeth, Angle Vale, Para Hills) and parts of the south (Morphett Vale, Hallett Cove, Reynella) are classified as Class H1 to H2 under AS 2870 — meaning the ground expands significantly when wet and contracts when dry. This seasonal movement is the single most common cause of concrete cracking in Adelaide.
A contractor who does not account for soil reactivity when designing your slab or driveway will leave you with a cracked, heaving surface within a few years. Our standard process on reactive clay sites includes:
- Soil classification check against AS 2870 before quoting
- Deeper excavation to remove reactive topsoil
- Thicker compacted DGB20 roadbase (150 mm on H-class sites)
- SL82 reinforcement mesh instead of standard SL72 on high-reactivity sites
- 0.2 mm polyethylene moisture barrier on all slab-on-ground work
- Control joints at 2.5–3 m centres (vs 3 m on stable ground)
