What Quarry Tile Is
Quarry tile Is A Type Of Unglazed Ceramic Tile Produced By Pressing And Firing Natural Clays And Shales At High Temperatures. The manufacturing process produces a dense, hard body with a natural matte finish that resists wear and heavy foot traffic. Unlike glazed ceramic tiles, quarry tile has color that runs through the entire tile body, so surface chips are less visible.

How Quarry Tile Is Made
The Manufacturing Process Involves Mixing Natural Clays And Shales, Pressing The Mixture Into Molds, And Firing It In Kilns At High Temperatures. During firing, the raw material vitrifies partially, increasing strength and reducing porosity. No surface glaze is applied, which creates the characteristic matt texture that enhances slip resistance and durability.
Typical Sizes, Colors, And Finishes
Common Quarry Tile Sizes Include 6″x6″, 8″x8″, 12″x12″, And Occasionally Rectangular Sizes. Standard colors are red, brown, gray, and black due to the natural clay composition; some manufacturers produce additional shades by altering clay mixes or adding pigments. Finishes are usually matte or textured for traction; polished quarry tile is uncommon.
Physical Properties And Performance
Quarry Tile Is Known For High Compressive Strength, Low Water Absorption, And Excellent Abrasion Resistance. Typical tiles have high Mohs hardness and can tolerate heavy loads, thermal changes, and frequent cleaning with commercial chemicals. The unglazed surface provides inherent slip resistance, especially when textured or scored.
Where Quarry Tile Is Used
Quarry Tile Is Widely Used In Commercial Kitchens, Restaurants, Food Processing Facilities, Warehouses, And Busy Public Areas. Its resilience to grease, heat, and heavy traffic makes it a top choice for industrial and institutional settings. It’s also used outdoors for patios, walkways, and pool decks where frost resistance and traction are important.
Advantages Of Quarry Tile
-
Durability: Exceptionally long-lasting under heavy foot and equipment traffic.
-
Slip Resistance: Natural matte and textured surfaces reduce slip hazards, especially when wet.
-
Low Maintenance: Tolerates frequent washing and strong cleaners without surface damage.
-
Stain Resistance: Less prone to visible staining since color typically runs through the tile body.
-
Cost-Effective: Often more economical over the life of the floor compared to higher-maintenance options.
Limitations And Considerations
Quarry Tile Has Some Limitations, Including Hardness That Can Be Unforgiving To Dropped Items And Less Design Flexibility Than Glazed Tiles. Because it is unglazed and porous relative to porcelain, grout needs sealing to prevent staining. Installation requires proper substrate preparation to prevent cracking, and the surface can be uncomfortable in residential barefoot settings.
Installation Overview
Correct Quarry Tile Installation Requires A Properly Prepared Substrate, Suitable Mortar, Appropriate Grout, And Skilled Layout To Accommodate Expansion And Drainage. A cementitious or thin-set mortar designed for heavy ceramic tile is recommended. For wet environments, slope and drainage planning are essential. Expansion joints and full-bed mortar techniques reduce the chance of tile cracking or popping.

Substrate Preparation
The Substrate Must Be Clean, Level, And Structurally Sound; Concrete Slabs Are Common, Often With A Moisture Mitigation System. For thin-set installation, the surface must be free of bond breakers, contaminants, and unevenness. On plywood or suspended systems, a decoupling membrane or cement backer board is typically required to prevent movement-related failures.
Mortar, Grout, And Jointing
Use A Heavy-Duty Thin-Set Mortar Or Full-Bed Cement Mortar, And A Cement-Based Grout With Sealant For Best Longevity. For commercial kitchen floors, epoxy grout may be specified for chemical resistance and durability. Grout joints are commonly wider (1/8″ to 1/4″) to account for dimensional tolerance and to help with traction.
Maintenance Best Practices
Routine Maintenance Includes Sweeping, Hot Water Mopping, And Periodic Deep Cleaning With Approved Degreasers; Grout Sealing Helps Prevent Stain Penetration. In high-grease areas, frequent degreasing prevents slip hazards and keeps tiles from becoming embedded with oily residues. Avoid acidic cleaners that can erode grout or weaken tile bonds over time.
Repair And Replacement
Individual Quarry Tiles Are Relatively Easy To Replace, But Repairs Require Matching Tile Color And Thickness To Maintain Uniformity. For high-wear commercial floors, maintaining an inventory of spare tiles helps speed repairs. Replacing tiles typically involves removing the damaged piece, cleaning the substrate, and installing a new tile with appropriate mortar and grout.
Comparing Quarry Tile To Other Flooring Types
Compared With Glazed Ceramic, Porcelain, And Natural Stone, Quarry Tile Offers A Unique Balance Of Cost, Durability, And Slip Resistance. Porcelain is denser and often less porous, making it more suitable for some residential or stain-sensitive applications. Natural stone provides a premium look but requires more maintenance. Quarry tile is frequently preferred where functionality and longevity are primary concerns.
Cost Factors
Tile Price Is Influenced By Size, Thickness, Brand, And Quantity; Installation Costs Reflect Labor Intensity And Substrate Work. On a per-square-foot basis, quarry tile materials are generally moderate in price, while labor costs can be higher due to heavier tiles and the need for professional installation for long-term performance.
Building Codes And Safety Standards
Commercial Installations Often Reference Building Codes And Health Department Standards Regarding Slip Resistance, Drainage, And Cleanability. Quarry tile is commonly specified in municipal codes for restaurant kitchens and food service areas because it meets many performance criteria related to hygiene and safety.
Environmental Impact And Sustainability
Quarry Tile Is Made From Natural Materials And Can Be Environmentally Favorable When Sourced Locally And Fired With Efficient Kilns. Its long lifespan reduces the need for frequent replacement, lowering lifecycle environmental impact. Reclaimed quarry tile is also available for sustainable renovation projects.

Design And Aesthetic Options
While Quarry Tile Is Typically Utilitarian In Appearance, Creative Layouts, Borders, And Combination With Other Materials Can Elevate Design. Mixing tile sizes, using contrasting grout, or pairing quarry tile with decorative accents can create visually appealing floors without sacrificing performance.
When To Choose Quarry Tile
Quarry Tile Is An Excellent Choice Where Durability, Slip Resistance, And Ease Of Maintenance Are Top Priorities, Especially In Commercial Kitchens And High-Traffic Areas. It is less appropriate in settings that prioritize a refined, polished aesthetic or where barefoot comfort and warmth are primary concerns.
Buying Tips
-
Specify Use-Case Requirements: Confirm expected foot traffic, moisture, and chemical exposures before selecting tile grade.
-
Request Physical Samples: Inspect texture, color variation, and thickness to ensure match with existing materials.
-
Buy Extra Tile: Purchase 5–10% extra for cuts and future repairs, or more for high-wear areas.
-
Choose Reputable Suppliers: Work With Manufacturers Or Distributors That Provide Technical Data Sheets And Installation Guidelines.
Common Myths And Misconceptions
Myth: “Quarry Tile Is Always Rough And Hard To Clean.” In Fact, Properly Maintained Quarry Tile Cleans Readily With The Right Degreasers, And Its Texture Enhances Safety. Another misconception is that quarry tile is obsolete; modern quarry tiles come in varied colors and precise manufacturing tolerances for contemporary use.
Resources And Standards To Consult
Consult Industry Standards From ANSI, ASTM, And Local Health Departments For Specifications On Abrasion Resistance, Water Absorption, And Slip Resistance. Manufacturer technical sheets, installation guides, and building code documents provide actionable details for architects and facility managers.
Case Studies And Typical Applications
Examples Include Restaurant Kitchens That Use Quarry Tile For Grease Resistance, Hospitals For Easy Sanitization, And Outdoor Plazas For Durable, Frost-Resistant Surfaces. These real-world applications illustrate how quarry tile meets both functional and safety requirements in demanding environments.
