Basaltina

also known as Basaltina di Viterbo, Basalt Lazio, Italian Volcanic Basalt

A dense, dark volcanic basalt from the highland plateau north of Rome (Viterbo, Lazio). Basaltina is prized for its deep charcoal-grey, near-uniform appearance and exceptional durability — one of the hardest Italian stones. Widely used for contemporary facade panels, exterior paving, pool surrounds, and architectural detailing in both Italy and international luxury projects.

Origin & quarry

Basaltina is the grey volcanic stone of the Viterbo district north of Rome — even-grained, durable and quietly modern. A classic Roman exterior stone that also reads beautifully indoors honed.

Geology. Pyroclastic volcanic stone (basaltic tuff/lava) from the Lazio volcanic district; fine even grain, warm-mid grey.

Where it works

Specify with confidence

Exterior paving and cladding (durable, frost-resistant)
High-traffic interior floors
Stairs and public realm
Contemporary minimal interiors

Use with care

Slightly porous — seal for stain resistance in food/wet areas
Finish drives tone: honed is darker, flamed/bush-hammered lighter

Good to know

Is Basaltina suitable for ventilated facade systems?

Yes — its high compressive strength and low absorption make it a prime candidate for rainscreen/open-joint ventilated facades, where dimensional stability and freeze-thaw resistance are critical.

How does Basaltina differ from Pietra Lavica?

Both are Italian volcanic stones, but Pietra Lavica is quarried in Sicily (Etna) and has a more textured, ropy lava surface. Basaltina from Viterbo is a more compact, finer-grained basalt suited to precision cut-to-size work.
