Geotextiles in civil engineering

Geotextiles in civil engineering

The majority of geotextiles are produced using classic or conventional fabric manufacturing techniques. The manufacturing processes for the production of geotextiles can be broadly classified in two categories, (1) classic and (2) special geotextiles.11 In classic geotextiles, the products of the textile industry, such as woven, knitted, nonwoven fabrics, etc., are considered, whereas special geotextiles, while having a similar appearance to classic geotextiles, are not the direct products of textile technology, i.e. webbing, mats, and nets. A typical classification of the production of geotextiles is depicted in Fig. 4.6.11

What is the difference between a woven and nonwoven geotextile?

The use of geotextiles has steadily grown over the past century. Geotextiles were initially derived from existing textiles that were readily available on the market, such as carpet back and upholstery fabric. Manufacturers have modified geotextiles to provide increased benefits to roadway construction. While there are two main types (wovens and nonwovens), there is often still some confusion as to which product to use on your Jobsite. Common misconceptions about the functions of a woven geotextile vs. a nonwoven geotextile can often lead to added confusion. This tech-note will go into detail about the two main types of geotextiles and their functions.  

Nonwoven Geotextiles

Nonwoven Geotextiles

The most common nonwoven is a needle-punched product. Staple fibers or continuous filaments are bonded by mechanically entangling the fibers with barbed needles. It looks and feels like black felt. Occasionally, the product will be manufactured in white or orange. Orange nonwovens serve as a warning barrier indicating contaminated soils.

What Is Geosynthetics Products

Geosynthetics is a general term for synthetic materials used in civil engineering. As a civil engineering material, it uses synthetic polymers (such as plastic, chemical fiber, synthetic rubber, etc.) as raw materials to make various types of products and place them inside, on the surface of, or between various soils. , To play the role of strengthening or protecting the soil.

They also offer excellent corrosion resistance, making them suitable for use in soil and water with different pH levels. both dry and wet conditions due to the use of plastic fibers. They also offer excellent corrosion resistance, making them suitable for use in soil and water with different pH levels.

In addition, nonwoven geotextiles have good water permeability due to the gaps between the fibers. They also exhibit good anti-microbial properties and do not harm microorganisms or insects.

These materials are lightweight and soft, making them easy to transport, lay, and construct, which makes them a convenient option for many different applications. Overall, nonwoven geotextiles offer a range of benefits that make them a popular choice for various civil engineering projects.
