Geotextiles have been used for thousands of years. Geotextiles were used
in roadway construction in the days of the Pharaohs to stabilise
roadways and their edges. These early geotextiles were made of natural
fibres, fabrics or vegetation mixed with soil to improve road quality,
particularly when roads were made on unstable soil. Only recently have
geotextiles been used and evaluated for modern road construction.
A geotextile is defined as any permeable textile material that is used with foundation, soil, rock, earth, etc to increase stability and decrease wind and water erosion. A geotextile may be made of synthetic or natural fibers. In contrast, a geomembrane is a continuous membrane-type liner or barrier Geomembranes must have sufficiently low permeability to control migration of fluid in a constructed project, structure or system. A geotextile is designed to be permeable to allow the flow of fluids through it or in it, and a geomembrane is designed to restrict the fluid flow.
Geotextiles can be woven, knitted or non-woven. Different fabric composition and construction are suitable for different applications. The non-woven geotextile is an arrangement of fibres either oriented or randomly patterned in a sheet, resembling felt. These geotextiles provide planar water flow in addition to stabilization of soil. Typical applications include access roads, aggregate drains, asphalt pavement overlays, and erosion control.
