Basalt stone slab BASALTITE®

for wallfloorfacade

Product overview
Basaltite® is a medium‑grey volcanic stone (leucotefrite) with leucite crystals set in a microcrystalline, compact matrix. Originating from lava flows of the Bolsena–Bagnoregio eruption centre, the material combines low porosity and mechanical properties suited to architectural use both indoors and outdoors.

Typology / Typical finishes

• Filled and polished
• Filled and honed
• Brushed
• Bushammered
• Honed unfilled
• Polished unfilled
• Sandblasted
• Sawn / unpolished

Petrography and certification
Classified as leucotefrite, Basaltite® is heavy, compact and hard. Laboratory tests (UNI standards) report high compressive and flexural strength and impact resistance. Certificate: University of Pisa – Department of Structural Engineering, Report No. 364/00.

Use and applications
Historically used for significant buildings and urban works, Basaltite® is suitable for a wide range of architectural applications thanks to its hardness, natural slip resistance and frost/heat resistance.

• Interior flooring
• Wall cladding and staircases
• Exterior paving and gardens
• Bathroom design
• Kitchen surfaces
• Artistic and sculptural works
