Composite geotextile is a new type of geosynthetic material made by bonding long-fiber woven geotextile with short-fiber needle-punched nonwoven fabric.
Product Features: The composite geotextile differs from the general woven fabric. Its most distinctive feature is that the intersections of the warp and weft threads do not bend, but remain in a straight state. By using binding lines to securely tie them together, they can uniformly and simultaneously bear external forces and distribute stresses. Moreover, when the material is torn instantly under applied force, the fibers will gather along the initial tear, thereby increasing the tear resistance.
Process: In the composite process, the warp binding line is repeatedly passed through the fiber layers between the warp, weft, and needle-punched geotextile, integrating them into a single structure. Consequently, the warp-knitted composite geotextile boasts high tensile strength and low elongation, while also retaining the properties of needle-punched nonwoven fabric. Therefore, it is suitable for reinforcement and enhancement, isolation and protection, and exhibits good water retention in both three-dimensional normal and horizontal directions. Due to its continuous solid matrix and pores, it provides a multi-porous filtering effect, making it a multifunctional geosynthetic composite material.
Composite geotextile features high tensile strength, low elongation, even longitudinal and transverse deformation, high tear resistance, excellent wear resistance, high permeability, strong anti-backflow properties, etc.
Primary Functions: The main functions of the warp-knitted composite geotextile include reinforcing, drainage, anti-backflow, protection, and isolation.
Application Range: Primarily used for:
1. Reinforced dam drainage, anti-seepage, base stress equalization, prevent ground deformation and sublayer sedimentation, accelerate consolidation drainage, and enhance the stability of ground strength.
Enhance slope backfill to improve stability.
3. Tunnels, pond level changes, soil erosion, underground pipe drainage, etc.
