Preto Carvaõ Basalt

This rich black igneous rock is characterized by a medium grain size which displays a subtle patterning and depth of color when honed, polished or water jetted. Basalt is formed from volcanic action and lava flows, which contribute to its uniform and consistent appearance. Deposits are harvested in large hexagonal columns, hence limiting the size for example of pavers, which are available up to 30" x 30" for full container orders. Larger pieces may be available on a limited basis.

Suggested Uses

Pavers, treads/risers, interior veneers, wall caps, coping and cubic fabrication.
