Manufacturer's Product Description

We are pleased to introduce Gunnison Basalt. Gunnison is an excellent choice for interior and exterior applications. It is a durable, hard stone which is resistant to freeze-thaw cycles. Its medium dark gray color and small markings are relatively consistent. Naturally occurring, small holes in the face can be filled if desired. Architects specify this material for interior flooring, exterior paving, stairs, and wall cladding. Gunnison Basalt is available in honed, cascade and polished finishes.
