Steinblock

Steinblock is a German term that translates to stone block. It denotes a natural block of stone quarried for construction, sculpture, or landscaping. Steinblocks are typically rectangular or cuboid in shape, and may be left rough or dressed to a specific finish, depending on their use. Sizes vary widely, from small blocks used in masonry to large blocks weighing several tons.

Materials commonly used for Steinblocks include granite, limestone, sandstone, marble, basalt, and travertine. The choice of material determines properties such as compressive strength, porosity, color, and weather resistance, which influence suitability for load-bearing walls, exterior façades, paving, or decorative elements.

Production involves quarrying the stone from an outcrop or bed, followed by cutting to size with saws or wire tools. After sizing, surfaces may be rough-sawn, finely dressed, or chamfered. Blocks can be left as rough rubble or laid in ashlar masonry, depending on architectural requirements.

Historically, stone blocks have been foundational to monumental architecture, from ancient temples and pyramids to classical and modern buildings. In quarrying, standardized block sizes were developed for transport and construction efficiency, while dressed blocks enabled precise fitting in masonry.

Steinblock also appears in catalogs and technical references as a descriptive term for any natural block of stone intended for building or sculpture. See also stone block, ashlar, masonry, quarrying.
