| Material and manufacture | Made from natural clay or shale and hardened in a kiln. Color is generally present throughout the fired body, though appearance varies by clay and manufacturing process. | Made from refined ceramic materials and fired at high temperatures. Porcelain tile is commonly defined by water absorption of 0.5% or less, but verify the product’s technical documentation. |
| Common used formats | Often rectangular brick shapes, including modular paver sizes. Actual dimensions and thickness vary by product and installation. | May include large-format tiles or outdoor pavers, commonly sold in thicker formats such as 20 mm. Not every porcelain tile is suitable for use as a paver. |
| Appearance | Typically has a traditional, textured brick appearance. Weathering and natural color variation can add character to reclaimed material. | Available in a wide range of colors and printed patterns, including stone- or concrete-like designs. Used pieces may show surface wear, fading, or edge damage. |
| Water and stain considerations | Absorption varies by product. Some clay pavers can absorb more water and may require careful selection for wet or freeze-prone locations. | Low water absorption is a characteristic of porcelain, but grout, joints, surface texture, and installation details still affect overall performance and cleaning. |
| Outdoor and freeze-thaw use | Can be suitable outdoors when the specific paver is rated for the site conditions. Check applicable product specifications and local requirements. | Can be suitable outdoors when specifically designed and rated for exterior paving. Confirm freeze-thaw suitability, thickness, and installation method before reuse. |
| Traction underfoot | Texture may provide useful grip, but traction depends on the surface finish, wear, dirt, and whether the paver is wet. | Traction varies substantially by finish. Choose a surface with appropriate wet-slip performance for the intended location; polished finishes may be unsuitable in wet areas. |
| Handling and installation | Individual units are generally manageable to handle, but reclaimed batches can vary in size and thickness. Sort and measure pieces before installation. | Large or thick pieces can be heavy, while thinner tiles may not be suitable for a paver installation. Follow the product’s specified base or setting method. |
| What to inspect when buying used | Check for cracks, spalling, chipped edges, uneven wear, and consistent dimensions. Ask about previous use and exposure to freeze-thaw conditions. | Check for cracks, chipped corners, surface scratches, and variation between pieces. Confirm that the product is an exterior-rated paver rather than a standard indoor tile. |
| Best fit for reuse | A practical option for brick-style paths, patios, and repair projects when the reclaimed units are sound and compatible with the installation. | A potential choice for contemporary patios and outdoor areas when the pieces are exterior-rated, sufficiently thick, and in good condition. |
