A layer consists of special components when more than half of its volume consists of special material. That material can be either natural or anthropogenic in nature. A layer consisting of special material is described less extensively than a layer that consists of soil or rock. Below the categories of special components and their descriptions can be found.

# Unbroken concrete

Antropogenic material: concrete that is not classified as debris, for example, a concrete slab.

# Geotextile

Antropogenic material: textiles and films used in ground improvement usually made of plastic.

# Used wood

Antropogenic material: wood or woody material that has been used. Examples include rice mats, foundation piles, shoring, shipwrecks.

# Charcoal

Antropogenic material: charred remains of wood due to combustion, usually broken pieces.

# Garbage

Antropogenic material: unspecified household waste.

# Human made chalk

Antropogenic material: lime-based human made material such as slaked lime or lime identifiable as an admixture.

# Filler material with plastics

Antropogenic material: filler material with a low specific weight consisting mainly of plastics and similar plastics, with expanded polystyrene as an example.

# Filler material with stones

Antropogenic material: filler material with a low specific weight consisting of man-made stony material.

Examples include bims, expanded clay pellets, flugsand foam concrete and foam glass.

# Woody plant remnants

Natural material: the woody, undigested remains of plants, such as stems, branches and woody roots.

# Not woody plant remnants

Natural material: the non-woody, undigested remains of plants, such as rootlets, cane stems and leaves.

# Debris

Antropogenic material: construction and demolition waste, often a mixture of stony materials made or worked by man.

# Mixture of soil

Antropogenic material: a mixture of the soil on site with a material such as cement or water glass. water glass itself is also included here.

# Stones

Antropogenic material: stones of natural material that have been used as ballast or dump rock or are the by-product of mining operations.

# Combustion residues

Antropogenic material: mineral combustion residues with a diameter ranging from less than 63 µm to greater than 2 mm.

# Fine combustion residues

Antropogenic material: mineral combustion residues with a diameter similar to that of silt and lutum (less than 63 µm).

# Medium coarse combustion residues

Antropogenic material: mineral combustion residues with a diameter similar to that of sand (0.063 to 2 mm).

# Coarse combustion residues

Antropogenic material: mineral combustion residues with a diameter greater than 2 mm.

# Road surfacing material

Antropogenic material: material used for paving of roads and yards. Examples include asphalt, concrete pavers, crushed clinker stones and tiles.

# Weathered boulders

Natural material: a boulder so weathered that the material is completely pulverized and can be pierced.
