Product Introduction
1、 Basic attributes
Geo Woven Fabric are permeable geosynthetic materials made from synthetic fibers such as polyester and polypropylene, processed through industrial processes such as needle punching, weaving, and thermal bonding. According to the process form, it can be divided into three categories: non-woven geotextile (such as short fiber/long fiber needle punched fabric), woven geotextile (such as woven fabric), and composite geotextile (multi-layer functional structure combination), which are commonly used functional materials in civil engineering.
2、 Core functions
Isolation: Separate building materials with different physical properties (such as soil, sand, and stone) to prevent material mixing and loss, and maintain structural layering stability.
Filtering: allowing water flow to pass through while effectively intercepting impurities such as soil particles and fine sand, avoiding structural failure caused by the loss of fine materials in water and soil engineering.
Drainage: By using fiber gaps to form internal water channels, excess liquids or gases in the soil can be quickly discharged, reducing the static water pressure of the structure.
Reinforcement: By enhancing the tensile strength and deformation resistance of soil through its own high strength characteristics, it improves the bearing stability of structures such as roadbeds and dams.
Protection: Disperse concentrated stresses such as water flow erosion and external impact, and protect soil or structures from erosion and damage.
3、 Main features
Stable performance: lightweight (unit area mass 100-1000g/m ²), high strength, able to maintain good mechanical properties in both dry and wet environments, suitable for complex working conditions.
Strong weather resistance: resistant to acid and alkali corrosion, resistant to microbial erosion, can be used for a long time in soil, water and other environments, and has a certain ability to resist UV aging.
Good functional adaptability: with controllable permeability, it can efficiently guide water and accurately filter, and different types of products can be selected according to engineering needs.
Convenient construction: The width is usually 4-9 meters, and the laying is flexible. It can be connected by overlapping, sewing or welding to meet the rapid construction needs of various engineering scenarios.
