Polished Basalt
Polished black basalt for interiors and feature walls.
Polishing brings out the deep, uniform black of Kayseri basalt and gives it an even gloss that is softer than the glare of granite. Polished basalt is specified for hotel lobbies, shopping centres, residential floors, wall cladding and stair treads in areas protected from frost. The stone is hygienic, easy to clean and keeps its colour under heavy foot traffic.
- Deep, uniform black without veins
- Suitable for floors, walls, stairs and countertops
- Recommended for interiors and covered areas
- Available finishes
- Polished
- Standard sizes
- 20×20 cm30×30 cm40×40 cm50×50 cm
Custom sizes, thicknesses, profiles and mixed finishes are produced to order from your drawings.
