Basalt Setts Volcanic Black

This natural basalt is supplied from Vietnam, home to rich volcanic deposits and a long-standing tradition of quality stone production.

Basalt is an extrusive igneous rock, formed when molten lava cools rapidly at the earth’s surface. This fast cooling process results in a fine-grained, tightly packed mineral structure, giving basalt its exceptional density and hardness. The result is a stone that’s highly resistant to weathering, abrasion, and heavy use. Making it one of the most durable materials available for outdoor paving.

6. Where does the basalt come from?

Corker’s Volcanic Black Basalt Setts are supplied from Vietnam, a region known for its rich volcanic deposits and long-standing stone production. Basalt forms when molten lava cools rapidly at the earth’s surface, creating a fine-grained and tightly packed structure. This natural formation gives the stone its exceptional density, hardness and resistance to wear, making it particularly well suited to outdoor paving.
