torkskikt

torkskikt is a Swedish term that literally translates to “dry layer.” The word is used in several technical contexts to describe a layer that either has a reduced moisture content or functions to manage moisture. In geology, a torkskikt refers to a paleosol or weathering layer that exists in a sedimentary sequence. These layers are often characterized by lower bulk density, higher porosity, and distinct mineral assemblages compared with adjacent strata, indicating periods of desiccation or limited water infiltration during deposition.

In civil engineering and road construction, torkskikt denotes a preparatory layer that removes excess moisture from subgrade soils before cementitious surfacing. The layer is typically comprised of compacted aggregate or a mixture of sand and binding agents, which reduces capillary suction and prevents delamination or cracking of the final pavement. Engineers design the thickness of a torkskikt based on expected climatic conditions and soil characteristics, aiming to achieve a stable, moisture‑controlled foundation for asphalt or concrete.

Textile manufacturers also employ the term torkskikt to describe a non‑woven or woven layer that is treated or positioned to expel or absorb sweat, thereby keeping the wearer dry. This functional layer often incorporates micro‑porous fibers or is bonded with hydrophilic coatings that wick moisture away from the skin to the outer surface, where it evaporates quickly. Such torkskikt components are common in sportswear, work shirts, and outdoor gear.

The usage of torkskikt in Swedish technical literature illustrates how short, descriptive compound words convey precise functional information. Whether in geology, construction, or textiles, the concept of a “dry layer” remains central to controlling moisture dynamics, improving material performance, and extending the lifespan of engineered systems.
