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!
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. Constructed from a series of needle punched pores, these fabrics allow water to flow through the material while blocking sediment, silt and other aggregates. This provides effective protection in areas dealing with filtration requirements or erosion control.
When compared to medium or heavy weight models, light weight fabrics offer a higher level of permeability. This has made them a common choice for use around pipes, french drains, asphalt overlay, or separation under pavers.
