Geotextile is a permeable fabric which, when used in connection with soil, has the ability to separate, filter, strengthen, protect, or drain. Usually made of polypropylene or polyester, the geotextile fabric comes in three basic forms: woven (like a sack bag), needle pressing (resembling feel), or heat bonded (resembling ironed feel).
Composite geotextiles have been introduced and products such as geogrid and nets have been developed. Geotextiles are able to withstand many things, are durable, and are able to soften the fall if a person falls. Overall, these materials are referred to as geosynthetics and any configuration --- geonet, geosynthetic clay liners, geogrids, geotextile tubes, etc. --- can produce benefits in geotechnical and environmental engineering designs.

Histori
Geotextiles were originally intended to be an alternative to granular soil filters. The original term, and sometimes used, the term for geotextile is filter cloth . The work originally began in the 1950s with R.J. Barrett uses geotextiles behind precast concrete walls, beneath precast concrete erosion control blocks, beneath large rock boulders, and in other erosion control situations. He uses different styles of monofilament woven fabrics, all characterized by a relatively high open percentage (varies from 6 to 30%). He discussed the need for adequate permeability and retention of the soil, along with adequate fabric strength and proper elongation and set the tone for the use of geotextiles in filtration situations.

Geotextile and related products have many applications and currently support many civil engineering applications including roads, airfields, railways, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and mud fencing or geotube site construction. Usually geotextiles are placed on the surface of the tension to strengthen the soil. Geotextile is also used for sand sand armoring to protect highland coastal properties from storm surges, wave action and flooding. A large sand-filled container (SFC) inside a dune system prevents storm erosion from processes outside of the SFC. Using a sloping unit rather than a single tube eliminates a damaging scour.
The erosion control guidelines comment on the effectiveness of the slope, the step shape in reducing the damage of coastal erosion from the storm. Geotextile-filled units provide "soft" armor solutions for highland property protection. Geotextiles are used as webbing to stabilize streams in drains and river swales.
Geotextiles can increase soil strength at a lower cost than conventional soil rupture. In addition, geotextiles allow planting on steep slopes, further securing the slopes.
Geotextiles have been used to protect Hominid fossil footprints from Laetoli in Tanzania from erosion, rain, and tree roots.
In building demolition, the geotextile fabric combined with the steel wire fence can contain explosive debris.
Coir (coconut fiber) geotextile is very popular for erosion control, slope stabilization and biotechnology, due to substantial mechanical strength of fabric. Coat geotextiles last about 3 to 5 years depending on the weight of the fabric. The product is degraded into humus, enriching the soil.
Design method
While many possible design methods or combinations of methods are available for geotextile designers, the final decision for a particular application typically takes one of three directions: design based on cost and availability, design based on specification, or design by function. An extensive literature on design methods for geotextiles has been published in journals reviewed by colleagues Geotextiles and Geomembranes.
