Stone blocks and slabs are pieces of natural rock formations that are used in sculptures and as building materials. Categories include marble, granite, sandstone, slate, limestone, quartzite, and bidasar. Travertine and onyx are also available. Some stone blocks and slabs are brushed, polished and honed. Others have a rough, textured surface and are slip resistant.
Typically, stone blocks and slabs are used in the design and construction of countertops, flooring, fireplaces, bathrooms, walkways, and kitchens. Additional building and construction applications include roofing and wall-cladding. Resistance to fire, water, and temperature changes are additional specifications to consider. Marble and granite are popular types of stone blocks and slabs. A metamorphic rock, marble is irregularly-colored with impurities. Colors include white, red, black, gray, pink and green. Mottled marble and banded marble are also available.
Typically, marble is used for interior and exterior flooring applications. Granite, another common building material, is used as both as structural and ornamental stone. An igneous rock, granite offers high compressive strength and durability. Granite blocks are used in monuments such as statues and headstones. Granite slabs are used in fabricating granite counter tops and granite flooring. Landscaping applications include retaining walls. Stone blocks and slabs include sandstone and slatestone (slate, slate stone) products. A sedimentary rock, sandstone is formed by the compaction of sand and held together by silica. Natural sandstone is hard and tough, but each type of quartz-based stone provides a different amount of porosity and compressive strength. Indian sandstone is used widely in both residential and commercial construction. Applications for sandstone include flooring, paving, and wall-cladding. Slate stones are similar to sandstones, but are less expensive than other floor and wall coverings. Natural slate stone is both fireproof and slip-resistant. Slate stone blocks and slabs are available in colors such as black, gray, copper, greenish gray and purplish grey. Limestone, quartzite, bidasar, travertine and onyx are available from suppliers of stone blocks and slabs. Limestone is a sedimentary rock with high resistance to freezing and thawing conditions. Limestone tiles and limestone slabs are often beige or tan in color, and are used as flooring materials. Quartzite is a medium-grained rock that is both fireproof and slip-resistant. Quartzite tiles and quartzite stones are used in applications ranging from roofing to flooring. Bidasar stone blocks and slabs are used for decorative purposes and landscaping. Travertine is a sedimentary rock used for paving patio and garden paths. Onyx is a form of quartz with alternating black and white bands.
