Quartzite has been used as flooring, staircase, and wall coverings. Based on the environment Quartzite was formed, it is known as a highly durable material. This environment formed Quartzite to be highly resistant to scratches as a result. However, Quartzite is a highly dense material and very heavy. Approximately 170 square feet of floor can weigh in excess of 2,000 pounds. It is imperative to take this weight into consideration when installing in a home or business. Quartzite ranks at a staggering seven on the hardness scale. Quartzite tiles are available in half inch to one inch thick pieces. Quartzite, similar to Marble, is highly shiny and smooth when polished. Also like Marble, Quartzite Flooring becomes a bit of a slipping hazard if its installed around water sources.
