3. • Geotextiles are a permeable synthetic textile material, made from either polypropylene or polyester. Geotextiles are used for several different applications in a range of civil and environmental engineering structures that are mainly associated with soil, there are 5 key functions that geotextiles perform: • 1.) Separation • 2.) Reinforcement • 3.) Filtration • 4.) Protection • 5.) Drainage www.nilex.com 3

4. • • What is a Nonwoven Geotextile? Nonwoven Geotextiles are produced by entangling fibres, long or short together, either through needle punching or other methods. Some additional thermal treatment is then applied to further improve the strength of the geotextile. Due to this manufacturing process and their permeable properties, non- woven geotextiles are generally best used in applications of drainage, separation, filtration and protection. Nonwoven fabrics are typically classified by their weight per square yard, for example a square yard of 6 oz. geotextile, weighs 6 ounces. They feel and look like felt. • • What is a Woven Geotextile? Woven Geotextiles are manufactured by blending and weaving fibres together on a loom, forming one uniform length. The result is a product that is not only strong, which makes them a great fit for applications like road construction and parking lots, but also remarkably well equipped to handle ground stabilisation problems. They are relatively impermeable (water does not flow through very well) and do not offer the best separation against fines. www.nilex.com 4
