DESIGN SUPPORT

A very hard form of igneous stone that’s regionally available from ancient volcanic deposits found mostly in the Chihuahuan Desert.  Texas basalt is widely suitable as either active (occassional to high human programmed usage) or passive usage.  Due to coloration, heat-gain in full sun is very high.  Albedo (light reflectivity) is low.  Basalt is an incredibly durable material that is often used as the aggregate in Texas highways.  Our basalt has a dark blue-gray color profile.
