The function and application scope of non-woven geotextile

Non-woven geotextile is a textile material made of polypropylene, polyester and other synthetic fibers through thermal bonding or needle punching processes. It has the characteristics of high strength, waterproof, water permeable, breathable, corrosion resistance and other characteristics. It is mainly used in civil engineering, water conservancy engineering, traffic engineering and other fields, and has a variety of functions and application scopes:

1. Prevent soil erosion: Non-woven geotextiles laid on the soil surface can effectively prevent the soil from being eroded by rain erosion, wind erosion, etc., and protect the soil from erosion and remain stable.

2. Soil isolation and reinforcement: Non-woven geotextiles can be used to isolate impurities between different soil layers and prevent different soil layers from penetrating each other. At the same time, they can strengthen the soil structure and improve the bearing capacity of the soil.

3. Drainage and filtration: Non-woven geotextiles have good water permeability and filtration properties, and can be used for drainage and filtration functions in projects, effectively controlling groundwater levels and eliminating surface water accumulation, while blocking concrete from granular soil.

4. Protect vegetation: Non-woven geotextiles can be used to protect vegetation growth, avoid soil erosion, promote vegetation growth and root development, and can withstand harsh climate conditions.

Non-woven geotextiles are widely used in road protection, river embankment protection, soil protection, ecological restoration and other aspects. They can improve the stability and durability of projects and protect the environment and ecological balance. In different engineering fields, non-woven geotextile plays an important role and is a multi-functional geomaterial.
