Basalto

Valli Basalto is a dark or black volcanic origin effusive rock, with a relatively low (from 45 to 52% by weight) silica content (SiO2).

Basalt originates from solidified magma in contact with air or water and is the main rock forming the outer layer of the oceanic crust.

Valli Basalto is used in constructions, as an aggregate for road paving, for railway ballasts, for self-locking screeds and for artistic creations.

Valli Basalto is available in multiple grain sizes, from 0 to 60 mm.
