Javed and Ashraf did the driveway on my property in Morphett Vale. Easy to book a day for them to come in and were accommodating to a few last minute adjustments. Quality workmanship which you don't see much of these days. Highly recommend.

I recently hired [team opal sa ] to do my driveway, and I couldn't be more pleased with the results. From start to finish, their professionalism, attention to detail, and quality of work were outstanding. The team was punctual, friendly, and worked efficiently to complete the job on time.The finished driveway looks fantastic – smooth, durable, and beautifully designed. They took the time to answer all my questions and kept me updated throughout the project. It's clear they take pride in their work, and it shows in the final product.

Adelaide has some of Australia's most reactive clay soils. Under AS 2870, suburbs are classified by soil reactivity — Class A (stable coastal sands) through to Class H2 (highly reactive clay in the northern and southern corridors). A concrete contractor who applies the same specification everywhere in Adelaide will leave you with a cracked slab on a Class H1 site within 3–5 years.
| AS 2870 Class | Adelaide Suburbs | Our Response |
|---|---|---|
| Class A / S | Glenelg, Henley Beach, Semaphore, Brighton | Standard 100 mm, SL72, 100 mm roadbase |
| Class M | Norwood, Unley, Campbelltown, Mitcham | Standard spec, control joints at 3 m |
| Class H1 | Salisbury, Para Hills, Morphett Vale, Hallett Cove | SL82 mesh, 150 mm roadbase, joints at 2.5 m |
| Class H2 | Elizabeth, Gawler, Davoren Park, Munno Para | Engineer spec, deep edge beams, SL82 mesh |
