When to use non woven geotextile

Non-woven geotextiles are versatile materials commonly used in civil engineering and construction projects for various applications. Knowing when to use non-woven geotextile depends on the specific requirements and conditions of the project. Here are some common scenarios where non-woven geotextiles are beneficial:

Separation: Non-woven geotextiles are often used to separate different soil layers or materials with varying particle sizes. Placing a non-woven geotextile between layers prevents mixing, maintains the integrity of each layer, and enhances the stability of the overall structure. This application is common in road construction, railway embankments, and parking lot installations.
Filtration: Non-woven geotextiles act as filters to allow water to pass through while retaining soil particles. They are used in drainage systems, retaining walls, and erosion control applications to prevent soil loss while allowing water to drain freely. By filtering out fine particles, non-woven geotextiles help maintain the integrity and longevity of hydraulic structures.
Reinforcement: In areas with weak or unstable soils, non-woven geotextiles can reinforce to improve load-bearing capacity and reduce soil settlement. By distributing loads more evenly and increasing soil strength, these geotextiles enhance the stability and performance of embankments, slopes, and other earth structures.

Erosion Control: Non-woven geotextiles are effective in erosion control applications where soil erosion is a concern due to water flow or wind action. By stabilizing soil surfaces and preventing erosion, these geotextiles protect slopes, shorelines, and other vulnerable areas from degradation and loss of soil.
Protection: Non-woven geotextiles can be used to protect geomembranes, liners, and other vulnerable materials from punctures, abrasion, and damage during installation and service life. By providing a durable barrier between the substrate and overlying materials, these geotextiles extend the lifespan of protective liners and enhance their performance.
Drainage: Non-woven geotextiles are commonly used in drainage systems to facilitate water flow while preventing soil migration. They are placed around perforated pipes or wrapped around aggregate drains to create a permeable barrier that allows water to enter while filtering out soil particles and debris.
Vegetation Support: Non-woven geotextiles can be used to support vegetation growth in landscaping and ecological restoration projects. By providing a stable substrate for plant roots to establish and grow, these geotextiles promote vegetation establishment, erosion control, and habitat restoration in various environments.
