Exploring the Different Types of Geotextiles and Their Various Applications

In the pursuit of enhancing soil characteristics, erosion management experts developed geotextiles. These synthetic, permeable textile materials are used in various civil and geotechnical engineering projects to improve soil conditions at construction sites. Since geotextiles are applied in roads, landfills, and other civil projects, they come in different types, each designed to suit specific applications.

This article explores the different types of geotextiles used in soil erosion.

Knitted Geotextiles

This type of geotextile is made by interlocking a series of loops of yarn. Knitting is different from weaving or bonding, and it entails using a knitted technique in conjunction with other methods.

Woven Fabric Geotextiles

This geotextile fabric type, also known as open mesh geotextiles, is made by weaving synthetic fibers to form a fabric with the desired qualities and attributes. During the weaving process, fabric stripes are interlocked together to make them strong and stable and more suitable for the project where they are needed.

These polypropylene strips can withstand a large amount of tension, making them ideal for separation and reinforcement purposes. The final product looks like plastic sheets, with the weave only visible after close inspection.

Non-Woven Geotextiles

Non-woven geotextiles are different types of geotextiles made using continuous filament yarn or short staple fibers. Instead of weaving the short staple fibers, the fibers are bonded using different techniques, including chemical, mechanical, or thermal bonding. Sometimes, the bonding combines two or more of these methods.

Non-woven geotextiles made using geothermal techniques usually have a thickness of about 0.5 to 1mm, while those bonded using chemical techniques have a thickness of about 3mm. The thickness means that non-woven geotextiles are suitable for filtration, separation, and protection processes in areas like roadways, landfills, and environmental projects.

Non-woven geotextiles are resistant to chemical and biological media in the soil, and those used in construction materials cannot be dissolved by water.

The Various Uses of Geotextiles

Geotextiles are synthetic fabrics that have a long lifespan, strength, and excellent filtering capabilities. As a result, they have different applications, including:

• Separation: Geotextiles are used to separate dissimilar materials in order to obtain the required soil characteristics.
• Filtration: Geotextiles allow water to move in both directions, which then prevents fine aggregates from moving between soil layers, hence solving drainage problems in a home area.
• Reinforcement: When a geotextile is introduced into the soil, it performs improvement duties, such as supporting loads, restraining movements, and changing the bearing plane in dams and roads built on poorly graded roads.
