Products Introduction：
Cushion Geotextile is a new type of geosynthetic material designed specifically for engineering protection and cushioning needs. It is made of polymer as the core material and processed through special weaving or non-woven processes, combining flexible structure and high strength performance. As a key auxiliary material in engineering construction, its core function is to provide buffering protection, infiltration regulation, and structural enhancement for soil, pipelines, roadbeds, and other structures in various infrastructure projects through its structural characteristics. It is an indispensable and important material in modern civil engineering, water conservancy engineering, transportation construction, and other fields.
Product Features：
1. Excellent cushioning and shock absorption performance: Cushion Geotextile has a unique fluffy fiber structure or multi-layer composite design, which can effectively disperse external load impacts through elastic deformation between fibers. When subjected to external forces such as vehicle crushing, soil settlement, or mechanical vibration, concentrated stress can be converted into dispersed force, significantly reducing the stress intensity on the surface and inside of the structure, reducing problems such as cracking and deformation caused by long-term impact, and providing long-term protection for the foundation structure.
2. Efficient penetration and barrier balance ability: The material itself has a uniform microporous structure, which allows for normal penetration of water and gas while accurately blocking impurities such as soil particles and sand. This feature not only avoids soil erosion caused by water flow erosion, ensures soil and water stability in the engineering area, but also prevents poor drainage caused by pore blockage, maintaining the hydrological cycle balance of the engineering environment.
3. Super durability and environmental adaptability: High molecular materials with strong weather resistance (such as polypropylene, polyester, etc.) are selected, and after special processing, they have excellent ultraviolet resistance, acid and alkali corrosion resistance, and aging resistance. Even in complex and harsh geological and climatic environments such as high temperature, severe cold, and humidity, it can maintain stable physical properties and structural integrity, with a service life of several decades.
4. Flexible and convenient construction characteristics: The product has a lightweight texture, much lower weight than traditional protective materials, and has good flexibility and extensibility. It can be cut and spliced according to the actual needs of the project, easily adapting to different terrain contours (such as slopes, curved surfaces, irregular foundations, etc.). The laying process does not require complex professional equipment, and can be quickly operated manually or mechanically, greatly reducing the construction period and lowering the installation cost of the project.
