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.
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
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.
