How big can Basalt blocks be?

Basalt blocks can vary in size depending on the source and location. Generally, they can range from small pieces, such as hand-sized rocks, to large boulders that weigh several tons. In construction, basalt blocks can be cut into dimensions that are manageable for transport and handling, typically with sizes that range from several inches to a few feet in length, width, and height. However, some specialized applications may require larger or custom-sized basalt blocks, which can be obtained through special orders or custom fabrication processes.
