Non-Woven Geotextile Fabric on Roadway

Geotex 501 Used for Road Project

Geotex 501- Non-woven Geotextile Fabric

Geotextiles have been used for many applications and have become very popular over the years. Starting off, geotextiles were created from other textiles that were available on the market including carpet backing and upholstery fabric. Also, the product has been modified to increase the benefits of road construction. There are two basic kinds of geotextiles, woven and nonwoven which can be confusing when deciding which one you need for your project. Misunderstandings about the use of woven geotextile versus nonwoven geotextile can also be somewhat confusing.  We will cover the two kinds of geotextiles and what they offer. You will know what to look for when choosing the right product for your needs.

Nonwoven Geotextile

The similarities between woven and nonwoven, both are made using a synthetic textile. Woven and nonwoven products have a random structure that is created by interlocking fibers. Woven and nonwoven are used in similar applications which can add to the confusion. The easiest way to distinguish between the two is their physical characteristics. Nonwoven geotextile looks and feels like felt and the material is fuzzy. Woven geotextile looks more like plastic.

There are many different methods for manufacturing nonwoven geotextiles. The most well-known and common method is using needle-punching. Needle-punched nonwoven geotextiles are created by taking a large number of small fibers and using a barbed needle to interlock the fibers together. Nonwoven geotextiles are generally used for separation combined with filtration and drainage functions when used in civil applications. Woven geotextiles are great for the separation of granular fill materials while offering substructure support. It's often used for road building.

While knowing the difference between woven and nonwoven can be challenging, generally, woven has higher strength values while nonwoven has higher flow rates and permittivity. Another easy way to know the difference is by starting with elongation. Nonwovens have much higher elongation than wovens. Nonwoven specifications will list the elongation as greater than 50%, while woven is listed between 5% to 25%.

Even though there are differences between their elongation and permittivity, their tensile strengths are similar as both are manufactured from similar materials. All these specs are important to consider when choosing the right kind of geotextile for your project. It is very important to select the right product for the right application.

If you are also dealing with erosion on your project. We have a wide variety of erosion mats that will meet your project needs.

Nonwoven Weight

Another difference between woven and nonwoven is the weight. The weight of woven geotextile is rarely specified because the product is used for separation and reinforcement and therefore does not rely on the actual fabric weight.

The weight of a nonwoven geotextile is specified if you are looking for a specific weight such as 8oz. For a long time now, nonwoven geotextiles have been measured by weight, such as the finished product would be 8oz per square yard. The other specifications including the strength and puncture resistance would be the result of the product's weight.

The use of geotextiles has grown and developed as the manufacturing processes have changed. Most nonwovens can be manufactured with a lighter weight but still achieve the same strength leading to lower costs. As with other things in life, there are exceptions such as using nonwoven as cushion geotextile underneath geomembranes. In this case, the puncture, weight, and thickness are more important than the permittivity and strength.

Note: If you are installing artificial turf, or pavers we have a Drainage mat roll available in multiple sizes and types.
