Geotextiles

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or woven monofilament (resembling fine open mesh).

Woven

Woven Geotextiles are planar, permeable textile structures produced by interlacing two or more sets of yarns or fibers. Woven geotextiles are used with soil, rock, earth, or any other geotechnical engineering-related material. They offer separation and some stabilization of various soils/aggregates.

Nonwoven

Nonwoven geotextiles are used for soil separation, drainage in transportation, building site, and water infrastructure projects such as subsurface drainage, permanent erosion control and roadway separation applications.  They are also commonly used as interlayers between hot mix asphalt courses to create a water resistant membrane and add tensile strength in the pavement to resist/retard crack propagation.

Monofilaments

Monofilament Woven Geotextiles are used in situations where high water flow rates are necessary. This type of woven geotextile is manufactured from extruded polypropylene monofilaments which are woven to create a very dimensionally stable and highly permeable geotextile.
