Geotextiles

A geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. More simply put, if it is made of fabric and buried in the ground it is probably a geotextile! Geotextiles have been in use for thousands of years dating back to the Egyptian Pharaohs. These early geotextile applications were basically natural fibers or vegetation mixed directly with soil. Modern geotextiles are usually made from a synthetic polymer such as polypropylene, polyester, polyethylene and polyamides. Geotextiles can be woven, knitted or non-woven. Varying polymers and manufacturing processes result in an array of geotextiles suitable for a variety of civil construction applications.

It is believed that the first modern applications of geotextiles were woven industrial fabrics used in 1950’s. One of the earliest documented cases was a waterfront structure built in Florida in 1958. This installation involved The Coastal Engineering Lab at the University of Florida and took place on private property that had been severely eroded by storms.

The first modern nonwoven geotextile was developed in 1968 by the Rhone Poulence company in France. It was a comparatively thick needle-punched polyester used in dam construction in France during 1970.

What is now considered as the first International Conference on Geotextiles took place in 1977 in Paris. The word "geotextile" was coined by Dr. J.P. Giroud in a paper presented at the conference.
Non-woven geotextiles resemble felt and provide planar water flow. They are commonly known as filter fabrics, although woven monofilament geotextiles can also be referred to as filter fabrics. Typical applications for non-woven geotextiles include aggregate drains, asphalt pavement overlays and erosion control.

A woven geotextile is a planar textile structure produced by interlacing two or more sets of strands at right angles. There are two types of strands: slit films, which are flat; and monofilaments, which are round. Woven slit-film geotextiles are generally preferred for applications where high strength properties are needed and filtration requirements are less critical. These fabrics reduce localized shear failure in weak subsoil conditions and aid construction over soft subsoils. Woven monofilament geotextiles are preferred for applications where both strength and filtration are a concern, such as shoreline rip rap applications.

Geotextile-related materials such as fabrics formed into mats, webs, nets, grids, or formed plastic sheets are not the same as geotextiles. These would fall under the more general category of geosynthetics. huahaiyuan offers a full line of geotextile products. Geotextile distributors, contractors, geotechnical engineers and homeowners are all welcome to call.

1. Separation For separation, a geotextile can be installed between two different soil materials. The geotextile will help to separate dissimilar materials so that the required soil characteristics can be obtained.

2. Filtration For filtration, geotextiles are used to allow water to move in both directions in a drainage system and can be used to prevent fine aggregates from moving between soil layers. Geotextiles can be used in both vertical and horizontal applications to help solve drainage problems around the home and along the roads.

3. Reinforcement When a geotextile is introduced in the soil for soil improvement, its design is based on factors such as: Friction or movement restraint Support of loads Changes in bearing failure plane Geotextiles are also used on dams and roads being built over poorly graded soils to allow for the steeper embankment.

4. Sealing A geotextile fabric can be filled with asphalt or other mixes to make it impermeable, thereby making it capable of stopping the flow of water in both directions. Geotextiles can be used to prevent contamination of soil or groundwater from pollutants above.

5. Protection For protection, geotextiles can be used to absorb stress and thus reduce or prevent damage and erosion in geotechnical structures. Embedding geotextiles in construction can help prevent significant damage, like soil erosion and wind damage.
