Nonwoven geotextiles are made of directionally or randomly orientated fibres, filaments or other elements, mechanically and/or thermally and/or adhesively bonded

Woven geotextiles are produced by interlacing two or more sets of yarns, fibres, filaments, tapes or other elements

Needle punched geotextiles are produced by entangling continuous or short fibres by needles. This so called mechanical bonding can be improved by additional thermal bonding

Thermally bonded geotextiles are produced by bonding randomly or directionally orientated fibres by thermal treatment.

Different polymers are used for the production of geotextiles. The selection of a polymer depends mainly on properties like melting point, density, melt flow index etc that influence the different production processes.

Usually the polymer is modified using additives and stabilizers in order to improve the characteristics. It is the final manufactured product that is of primary interest to the end user.

Geosynthetics is the generic term for products where at least one component is made from a synthetic or natural polymer used in contact with soil and/or other materials in geotechnical and civil engineering applications

Geotextiles are planar, permeable, polymeric textile products and are one type of geosynthetics.

• Improve the structural behaviour of the soil
• Substantial materials and manpower savings
• Fast installation
• Widely available
• Replace difficult designs with natural materials
• Save raw material resources
• Competitive cost (more economical construction)
