Uses of Granite

Granite is one of the most popular building materials. It has been used for thousands of years in both interior and exterior applications. Granite dimension stone is used in buildings, bridges, paving, monuments and many other exterior projects. Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other design elements. Granite is a prestige material, used in projects to produce impressions of elegance and quality. Some interesting uses of granite are shown below.

Granite Countertops

One of the most familiar uses of granite in the United States is in kitchen countertops. The
countertop pictured above was made from a solid slab of granite that was cut to custom shape and edge-finished. Increased demand for granite countertops has inspired a large number of kitchen contractors to acquire the expertise and equipment to install them. As a result they can usually be ordered from and installed by a local dealer instead of a company located hundreds of miles away. For this product, increased demand has actually reduced the installed price to a level that is within reach of the average homeowner. Pictured above is a pink granite kitchen countertop.

Granite Building Stone


The building above was built with granite blocks. Granite blocks for construction can be rough on all sides or finished on one or more sides. In this photo, a combination of rough and finished granite surfaces produce an elegant appearance. Note how most of the blocks used in this wall have both rough and finished sides. This yields tightly fitting joints but a rough surface texture. However, blocks used at window sill and roofline levels are finished on all sides. Rough-cut blocks are the least expensive and provide a rugged appearance. Finishing the blocks is expensive but yields a more refined appearance. (Image by Jim Plumb © iStockphoto.com.)

Granite Facing Stone

In large construction projects granite can be used in two different ways: 1) as a structural element, and 2) as decorative facing or veneer. Both of these are shown in the Arlington Memorial Bridge over the Potomac River at Washington, D.C. above. Visible immediately above the water line in this photo are the large rectangular granite blocks that were used in the piers of the bridge. These blocks are a structural use of granite. The visible surface of the bridge above the piers is covered with a thin veneer of facing stone to provide an attractive appearance. (Image by Klaas Lingbeek-van Kranen © iStockphoto.com.)

Granite Paving Stone

Granite paving stones or "pavers" can make a colorful and interesting way of paving a driveway or patio. The beauty of natural stone, combined with expert craftsmanship and design can produce a unique and lasting result. In the past granite blocks were often used to pave city streets. However, concrete and asphalt have replaced most of this work because of the lower material and construction cost. (Image by Arkady Mazor © iStockphoto.com.)

Granite Curbing

Granite is often used as a street curbing. Curbs made from granite are more durable than those made of concrete. They also provide a more decorative appearance. (Image by Arkady Mazor © iStockphoto.com.)

Granite Monument

Granite does not need to be quarried to be used. Mount Rushmore, a granite monument in the Black Hills of South Dakota is a tribute to George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln that is carved directly into the mountain.
