Bluestone tiles and pavers, natural split, with the 600x400x20mm tile format this page is really about, alongside 30mm pavers in 600x400mm and 800x400mm. The stone is basalt, deep grey with a blue cast and a fine peppered grain.
The 20mm Tile Format
At 20mm, bluestone becomes an on-slab product: bond it to cured concrete or screed with a flexible cement-based adhesive for alfresco floors, verandahs, covered terraces and interior floors that want the bluestone look for real. The thinner section keeps weight and cost down where there is no traffic loading, and it steps down neatly from an indoor slab height to meet door thresholds.
People pricing bluestone-look porcelain for interiors land here often, and it is a fair comparison to run. Porcelain is lighter and never needs sealing. Real bluestone brings natural variation, a face that wears in rather than wearing through a printed layer, and repairs that always match because there is no batch print. Ask for a free sample and put it next to the porcelain swatch; the difference is easier seen than described.
When You Want the 30mm Pavers Instead
Driveways, anything on road base rather than a slab, and open weather-exposed paving are 30mm territory. That format has its own page at bluestone pavers with the base and laying detail. Same quarry, same colour, so a 20mm interior floor can run out to 30mm external paving without a visible change.
Working With Bluestone
Basalt is dense, hard and acid-resistant, which makes it one of the most forgiving dark stones for kitchens and dining areas; spilt wine and citrus do not etch it the way they mark marble or limestone. Seal after laying to even out the colour and simplify cleaning. The stone reads darker wet, and a colour-enhancing sealer holds that deeper tone permanently if you want it.
Bluestone crates travel interstate on our regular runs, with Brisbane and Sydney orders both common. Matching pool copings, treads and crazy paving complete the set, and the full range is under bluestone. Samples are free. Direct import, Keysborough dispatch, freight quoted Australia wide.
