Need a rock solid base for the new shed, garage or carport? We laser-level every slab so your mower glides in and your tools stay dry. Built with an extra vapor barrier to handle Adelaide’s salty air, our slabs come with a lifetime workmanship promise.

If you’re dreaming of a new shed, garage or workshop, the very first step is a rock solid floor. That’s where we come in. Opal SA Construction is a small, family-run team right here in Adelaide, and we make shed slabs that stay flat, crack-free and look great for years.

We pour three simple types:

• Plain grey – tough, neat and kind on the wallet.

• Exposed aggregate – tiny stones that give a classy, non-slip finish.

• Coloured concrete – pick a shade you love and it runs right through the mix, so chips never show.

From the Adelaide Hills to the coast, we know the local soil and the wild weather, so every slab we lay is ready for scorching summers, heavy storms and whatever you choose to park on top. One friendly crew turns up on the day we promise, cleans up after ourselves and leaves you with a floor you can trust for life.
