6 Types of Stone Commonly Used for Projects

Variety of stonesThere are countless types of stone that can be used as materials for building. Each stone is unique, not all stones are equal, and some perform better when you use it for materials. At Petrillo Stone, we commonly use 6 materials in our projects:

  1. Basalt: This stone is between medium and fine grain. It’s dark-colored and composed of plagioclase and pyroxene minerals. This stone is commonly used to build roads, bridge piers, dams, river walls, and statues.
  2. Granite: Granite has a crystalline structure, and the grain can range from fine to course. It’s mostly made up of quartz and feldspar, with a little bit of mica and amphibole. Granite is used in buildings, bridges, paving, and monuments. Indoors, it can be used for tile floors, stair treads, and countertops.
  3. Sandstone: Sandstone is commonly combined with silica cement, and this mix is used to build heavy, solid structures. It’s made up of sand grains and a mix of silt or clay particles to occupy the space between the sand grains.
  4. Limestone: We commonly use limestone although not all limestone is usable. Certain varieties have high clay content making them non-durable. But, limestone is compact and dense which makes it great for building materials for floors, roofs, and pavements. Salty air can abrade it, so it’s best not to use it in coastal areas.
  5. Slate: Slate is made of quartz, clay minerals, and mica. It is extremely fine-grained and is used to make roofing tiles and pavers.
  6. Marble: Marble is known to be strong, uniform, imperious, and polishes beautifully. It’s made out of crystallized carbonate minerals. It’s easily carved, hence all the ancient statues carved in marble.
