Geotextiles are permeable fabrics made from polymers such as polyester, polypropylene, or polyethylene. They are engineered to be used with soil, rock, earth, or other geotechnical materials as a part of civil engineering projects. The primary function of geotextiles is to separate, filter, reinforce, protect, or drain in various construction projects.

One of the key advantages of geotextiles is their ability to increase the stability and load-bearing capacity of soil. They can also prevent the mixing of different types of soil and filter out fine particles to prevent clogging in drainage systems. Geotextiles are also resistant to UV radiation, making them suitable for outdoor applications.

Geotextiles are used in a wide range of applications, including road construction, landfill liners, erosion control, and slope stabilization. They can be used in various forms, such as rolls or sheets, and come in different weights and thicknesses to suit specific project requirements.

The installation of geotextiles typically involves laying them out in the desired location and securing them in place with pins or stakes. It is important to ensure that the geotextile is properly overlapped and sealed to prevent any gaps or leaks. Proper installation is crucial to ensure the effectiveness of the geotextile in the project.

Geotextiles are available in various dimensions, such as rolls with widths ranging from 1.5 meters to 6 meters and lengths up to 100 meters. The specific dimensions required will depend on the size and scope of the project.

In summary, geotextiles are versatile and essential materials in civil engineering projects, offering numerous benefits such as increased stability, filtration, and protection. With proper installation and selection of the appropriate type and size, geotextiles can significantly enhance the performance and longevity of various construction projects.
