Subject field(s)
  • Technical Textiles
  • Man-Made Construction Materials
  • Soil Mechanics (Engineering)
DEF

A permeable, polymeric material, which may be woven, nonwoven or knitted, used in geotechnical and civil engineerinig applications. [Definition standardized by ISO.]

CONT

Also known as geofabrics, filter cloths, support fabrics, or civil engineering fabrics, geotextiles are membranes used to stabilize soils. For that purpose, permeable fabrics made of synthetic fibers with high tensile strength, even when wet, large modulus of elasticity, high ductility, and negligible creep when under load are usually used.... These fabrics may be woven or nonwoven. Made of such synthetics as polypropylene, the nonwoven fabrics are needle-punched for permeability to water.

CONT

Other functions of geotextiles include erosion control, filtration, and drainage through and along the plane of the fabric.

OBS

Geotextiles are defined as permeable textiles used in conjunction with soils or rocks ... In contrast, geomembranes are defined as impermeable membranes which can also be used in conjunction with soils or rocks.

OBS

geotextile: term standardized by ISO.

French

Domaine(s)
  • Textiles techniques
  • Matériaux de construction artificiels
  • Mécanique des sols
DEF

Tout produit ou article textile perméable, utilisé dans les travaux de génie civil.

CONT

Tissé, non tissé, tricoté ou composite, le géotextile peut jouer un rôle hydraulique (fonction drainante, fonction filtre), ou un rôle mécanique (fonction réparation, fonction renforcement, fonction support ou conteneur).

OBS

Il existe deux types principaux de géotextiles, perméables et imperméables. Ces derniers [...] sont souvent appelés géomembranes, et le terme géotextile est réservé aux textiles perméables apparus après 1960.

OBS

L'utilisation des géotextiles, appelés à l'origine feutres synthétiques anticontaminants, doit permettre la respiration des plates-formes par capillarité verticale [...]

OBS

géotextile : terme normalisé par l'ISO et uniformisé par le CN [Compagnie des chemins de fer nationaux du Canada].

PHR

Géotextile anti-racine.

Spanish

Campo(s) temático(s)
  • Textiles técnicos
  • Materiales de construcción artificiales
  • Mecánica del suelo
CONT

Geotextiles: son materiales permeables que pueden ser “tejidos” o “no tejidos” y se utilizan generalmente para filtrar y conducir fluidos, separar suelos de diferentes características, reforzar suelos débiles y proteger a las geomembranas de los posibles daños de piedras angulares u otros objetos.

OBS

El nombre geotextil surge del uso exclusivo de la tecnología textil para su fabricación, y porque su empleo más importante está relacionado con el suelo (geo). Con el avance de la tecnología del plástico, se empezaron a utilizar componentes a partir de polímeros, por tal razón se creó una categoría más amplia que permitiera agrupar a todas las variantes, denominada geosintéticos.

OBS

Existen diferentes tipos de geosintéticos: los geotextiles, las geomembranas, geomallas, georedes, geoceldas, geomantas, biomantas y la combinación de ellos: los geocompuestos.

Record 3 1991-02-06

English

Subject field(s)
  • Man-Made Construction Materials
  • Joints and Connections (Construction)
  • Nonwoven Textiles
CONT

Nonwoven geotextiles are formed from filaments or fibers arranged at random and bonded together into a planar structure. The filaments or the fibers are first arranged into a loose web, then bonded together using one, or a combination, of the following processes: Chemical bonding .... Thermal bonding .... Mechanical bonding by needlepunching : thousands of small barbed needles, set into a board, are punched through the loose web and withdrawn, leaving filaments or fibers entangled. One thus obtains needlepunched nonwoven geotextile.

French

Domaine(s)
  • Matériaux de construction artificiels
  • Joints et assemblages (Construction)
  • Nontissés (Industries du textile)
DEF

Géotextile non-tissé dont la cohésion est assurée mécaniquement par l'enchevêtrement de fibres ou fibrilles à l'aide d'aiguilles à barbes.

OBS

Pour géotextile non-tissé ou non-tissé lié mécaniquement: Non-tissés voie fondue liés "mécaniquement" [...] La longueur infinie des filaments constituant les non-tissés voie fondue est avantageuse, car la liaison mécanique au moyen d'aiguilles de forme particulière permet d'obtenir une cohésion plus grande de la nappe.
