Natural Stone Tile and Slab

Natural stone slabs are commonly sawn from rough blocks of stone by reciprocating gangsaws using steel shot as abrasive. More modern technology utilizes diamond wire saws which use less water and energy. Multi-wire saws with as many as 60 wires can slab a block in less than two hours. The slabs are finished (i.e., polished, honed), then sealed with resin to fill micro-fissures and surface imperfections typically due to the loss of poorly bonded elements such as biotite . The fabricators shop cuts these slabs down to final size and finishes the edges with equipment such as hand-held routers, grinders, CNC equipment, or polishers. Industry standard thicknesses are 3/4" (2 cm) and 1.25" (3 cm). Often 2 cm slabs will be laminated at the edge to create the appearance of a thicker edge profile.

Natural stone tile is a thin modular stone unit, commonly 12 in. square (30.5 cm) and 3/8 in. (10 mm) thick. Other popular sizes are 15 in. square (38 cm), 18 in. square (46 cm), and 24 in. square (61 cm); these will usually be thicker than the 12 in. square. The majority of tile has a polished finish, but other finishes such as honed are becoming more common. Almost all stone tile is mass-produced by automated tile lines to identical size, finish, and close tolerances. Exceptions include slate flooring tile and special orders: tile with odd sizes or shapes, unusual finishes, or inlay work. In summary, the automated tile line is a complicated complex of cutting and calibrating machines, honing-polishing machines, edging machines that put on flat or rounded edges, and interconnecting conveyors to move the stone from the slab input to the final tile product. The stone for tiles is most commonly marble, but often is granite, and sometimes limestone, slate, or quartz-based stone.

Here are some typical finishes for natural stone slab and tile:

  • Polished finish - a glossy surface which brings out the full color and character of the stone.
  • Hone finish - a satin smooth surface finish with little or no gloss. This is recommended for commercial floors.
  • Thermal finish - a surface treatment applied by intense heat flaming.
  • Diamond sawed - finish produced by sawing with a diamond toothed saw.
  • Rough sawn - a surface finish resulting from the gang sawing (or frame saw) process.
  • Bush-hammered - a mechanical process which produces textured surfaces. Texture varies from subtle to rough.

Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. Granite is famous for its durability, hardness, better abrasion resistance and relatively high resistance to both acid and alkali attacks, non-magnetic and non-conductor of electricity. So granite is suitable for flooring, wall cladding, countertop, vanity top and tombstone.

Marble is a non foliated metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite. Marble has always been highly valued for its beauty, strength, and resistance to fire and erosion. With its unque color and texture, marble is a good choice for flooring, sculpture, wall cladding, fireplace, column, memorial, vessel sink and so on.

Sandstone is very Hard, Compact, Fine grained, equi-granular homogeneous rocks of sedimentary nature and highly resistant to acids, alkalies and thermal impact. Sandstone products is one of the main material used for flooring, wall cladding, carving and architectural uses as pillars, arches, garden furniture, fountains, landscaping products and stone arts and crafts.

Travertine is sometimes known as travertine limestone, sometimes as travertine marble.these are the same stone, even though it is neither limestone or marble. Travertine is one of the most frequently used stones in modern architecture, and is commonly seen as façade material, wall cladding, and flooring. The lobby walls of the modernist Willis Tower in Chicago, Illinois are travertine.
