Quarry tile

Quarry tile is a building construction material, usually ¹⁄₂ to ³⁄₄ inches (13 to 19 mm) thick, made by the extrusion process from natural clay or shales.^[1][2]

Sizes and shapes

The most traditional size in the US is nominally 6 in × 6 in × ¹⁄₂ in thick. Other common sizes include 4 in × 8 in and 8 in × 8 in.

Finishes

Traditional quarry tile was unglazed and either red or gray; however, modern "decorator" tiles come in a variety of tints and finishes. Industrial quarry tile is available with abrasive frit embedded in the surface to provide a non-slip finish in wet areas such as commercial kitchens and laboratories.

Uses

Quarry tile is extensively used for floors where a very durable material is required. It can be used either indoors or outdoors, although freeze-resistant grades of tile should be used outdoors in climates where freeze-thaw action occurs. Quarry tile is used less often as a wall finish and is occasionally used for countertops, although the wide grout joints can make cleaning of countertops difficult. Most commercial kitchens require a quarry tile to be used because of its slip resistant and non porous properties.

Installation

For floors, quarry tile is usually set in a thick bed of cementitious mortar. For wall applications, it can be set in either a thick bed of cementitious mortar or a thin bed of mastic. For both floors and walls, the joints between tiles are usually grouted with cementitious grout. Grout joints are traditionally about ³⁄₈ inch in width. Matching trim shapes such as coves, bases, shoes, and bullnoses are available to turn corners and terminate runs of the tile.
