Division of geosynthetics
- Woven geotextiles – manufactured by interlacing two or more arrangements of yarns, fibres, filaments, bands or other elements,
- Non-woven geotextiles – manufactured in the form of a pile of fibres of an ordered or random orientation, joined by friction and/or cohesion and/or adhesion (needled, stitched, thermally, chemically bonded, etc.),
- Geoknit fabric – manufactured by interlacing loops of one or more yarns, fibres, filaments or other elements,
- Woven geomesh.
Permeable polymeric structural materials, which may be in sheet or strip form, is also a group of very heterogeneous products, difficult to define in general terms, to which manufacturing, inspection and testing methods, typical of geotextile products, are applied. Related products include cellular geomesh – products with an open structure of interconnected strips, forming quadrangular or hexagonal “cells” (“honeycomb”), filled after laying with backfill (soil or aggregate)
- Geomesh (geogrids) – flat structures containing a regular, open grid of internally connected tensile strength elements; geomesh is also manufactured using techniques other than weaving: hot-drawing, laying and gluing, and welding,
- Drainage geogrids,
- Cellular geosynthetics,
- Polymeric geosynthetic barriers,
- Geosynthetic clay barriers,
- Geosynthetic bitumen barriers
Composite materials, comprising one or more geotextile or related products, this group includes a wide variety of products, combined with different polymeric, mineral or other materials (e.g. metal); geocomposites used in earthworks are composed of geotextile materials (e.g. geomesh or geogrids combined with a non-woven fabric), as well as mineral additives.
