Basalt paver
POLISHED SLAB

Basalt is a volcanic stone that has been used in architecture for centuries. Basaltina, one of the premium basalts in Stone Source's catalog of materials, has a particularly rich history. It is quarried near Rome and was used by the ancient Romans to build roads and monuments. Examples of its uses in architecture can still be seen still today. Basalts are rich in magnesium, feldspar, pyroxene and iron, with hints of olivine and amphibole; all of which are siliceous materials similar to those in a granite. Although Basalts boast the durability of a granite, they tend to have the consistent coloration, markings and subtlety of a limestone.

Geology of Basalt

A volcanic (igneous) stone that has been used in architecture for centuries and is thought to be one of the main components of oceanic crust. The fissures and small holes in the surface are evidence of the earth’s natural gasses flowing through and escaping from the stone. Basalts are rich in magnesium, feldspar, pyroxene and iron, with hints of olivine and amphibole; all of which are siliceous materials similar to those in a granite.

General Information

Basalt is a porous material with naturally-occurring holes that may remain unfilled or be factory-filled with resin or cement. Basalt will stain when exposed to oil and highly-pigmented liquids.

Care + Maintenance Tips

  • Do not use resin-filled material outside, as the resin will discolor over time. Choose cement-filled or unfilled materials as an alternative.
  • Always seal this material prior to grouting or use.
  • Always use a grout that is similar in color to the stone to avoid a picture-frame effect.
  • To reduce the appearance of staining in kitchen countertop applications, always wipe up spills immediately. Oil and highly-pigmented liquids can penetrate and stain the stone and may need poultice to remove the stain.
