Soil-cement - A well compacted mixture of soil, cement and water to produce a hard soil with permanent cohesion. Used for road building and slope protection.

Geotextile - Any permeable textile (natural or synthetic) when used as a civil engineering material in conjunction with soil, rock or any other material for geotechnical application.
Geotextiles have mainly the following uses: drainage. filtration, separation of materials, reinforcement, erosion protection.

Woven material or Woven fabric     A (geo)textile formed by interlacing (usually at right angles) two or more sets of threads, fibres, filaments. tapes or other elements.

Woven geotextile    A (geo)textile formed by interlacing (usually at right angles) two or more sets of threads, fibres, filaments. tapes or other elements.

Non-woven material -  A (geo)tekstile produced in the form of a felt or of another manufactured sheet, where fibres (or filaments or other elements), directionally or randomly oriented, have been bonded mechanically and/or thermally and/or chemically.

Non-woven geotextile -  A (geo)tekstile produced in the form of a felt or of another manufactured sheet, where fibres (or filaments or other elements), directionally or randomly oriented, have been bonded mechanically and/or thermally and/or chemically.

Knitted material - A (geo)textile produced by interlooping one or more yarns, fibres, or other elements.

Knitted geotextile - A geotextile produced by interlooping one or more yarns, fibres, or other elements.

Geomembrane - Membrane formed by a thin flexible sheet of synthetic polymers or asphaltic material of very low permeability to be used as liner or barrier in geotechnical engineering systems so as to control fluid migration.

Permittivity - Permeability divided by the thickness of the material.
