Natural stone is used as architectural stone (construction, flooring, cladding, counter tops, curbing, etc.) and as raw block and monument stone for the funerary trade. Natural stone is also used in custom stone engraving. The engraved stone can be either decorative or functional. Natural memorial stones are used as natural burial markers.
Concrete paver blocks laid in a circular pattern Concrete paver blocks in a rectangular pattern. A paver is a paving stone, sett, tile, [1] brick [2] or brick-like piece of concrete commonly used as exterior flooring. They are generally placed on top of a foundation which is made of layers of compacted stone and sand.
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. [1] Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's ...
Over 1,000 mustatils, clustered in groups of 2–19, are spread out across a ritual landscape covering 200,000 square kilometres. They range from 20 to over 600 metres in length, with walls that are 1.2 metres high. Some of the sandstone blocks used in their construction weigh more than 500 kilograms. [1] [2] [3]

Ashlar may also be random, which involves stone blocks laid with deliberately discontinuous courses and therefore discontinuous joints both vertically and horizontally. In either case, it generally uses a joining material such as mortar to bind the blocks together, although dry ashlar construction, metal ties, and other methods of assembly have ...
Other shapes include rectangular blocks used for stair treads, sills, and coping (coping is sometimes nonrectangular). The shapes subject to foot traffic will usually have an abrasive finish such as honed or sandblasted. The stone is mostly limestone, but often is quartz-based stone (sandstone), or even marble or granite.
The sandstone was quarried as dimension stone, ton stone, and rubble stone, with dimension stone the most marketable and costly. Blocks of dimension stone typically measured 8 by 4 by 2 ft (2.44 by 1.22 by 0.61 m). [50] The byproduct of removing the dimension stone was rubble stone, which was either sold cheaply or discarded entirely. [51]
