Sandblasted Basalt
Fine-grained, non-slip surface for exterior paving, stairs and pool surrounds.
Sandblasting gives basalt an even, velvety texture with an excellent slip rating, without losing the stone's dark tone. It is the finish most often chosen for exterior floors, stair treads, ramps, pool decks and wet areas where safety matters. Devtaş basalt was used extensively at the Presidential Complex in Ankara.
- Excellent slip resistance (EN 14231)
- Even texture, consistent colour
- The standard choice for exterior floors
- Available finishes
- Sandblasted
- 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.
