Non-Woven Short-Fiber Geotextile: The Versatile and Cost-Effective Engineering

Product Specification

Product Overview:
Our non-woven short-fiber geotextile is a premium, needle-punched polyester fabric engineered for superior performance in separation, filtration, drainage, and protection applications. Its random fiber orientation and porous structure make it an ideal, economical choice for a wide range of civil, environmental, and construction projects. This versatile material is designed to enhance project longevity, stability, and efficiency.

Key Product Characteristics & Advantages:

• Exceptional Separation: Acts as a durable barrier between dissimilar soil layers (e.g., subsoil and aggregate). This prevents intermixing, maintains the structural integrity of the base material, and ensures long-term stability for roads, pavements, and other structures.

• Superior Filtration: Its unique permeable structure allows for the free passage of water while effectively retaining soil particles. This critical function prevents erosion and soil loss, protecting drainage systems from clogging and ensuring their continued performance.

• Reinforcement & Stabilization: Although not a primary geogrid, the fabric provides modest tensile strength to help distribute loads and stabilize soft subgrades, improving the performance of unpaved roads and temporary access areas.

• Puncture & Tear Resistance: The needle-punched manufacturing process creates a robust fabric with high resistance to punctures and tears during installation and throughout its service life, even when subjected to stress from sharp stones or uneven surfaces.

• Excellent Permeability: Offers high water flow capacity in its plane (transmissivity) and across its plane (permittivity), facilitating efficient drainage and dissipation of hydrostatic pressure behind retaining walls or in drainage ditches.

• UV & Chemical Resistance: Offers good resistance to ultraviolet degradation and many soil chemicals, ensuring consistent performance in exposed conditions before backfilling.

• Cost-Effectiveness: Provides an incredibly economical solution without compromising on essential engineering functions, offering outstanding value for large-scale projects.

• Ease of Installation: Lightweight, flexible, and easily cut to size. This simplifies handling and significantly reduces labor costs and construction time.
