Continuous Filament Geotextile is a high-performance geosynthetic material primarily manufactured from continuous filaments (e.g., polyester) via advanced processes such as spunbonding or needle-punching. It exhibits exceptional mechanical properties, with stable tensile strength and elongation under both dry and wet conditions, while its inter-filament void structure endows it with excellent water permeability. Widely used in civil engineering, hydraulic projects, and road construction, it fulfills functions like soil reinforcement, filtration, drainage, and erosion control, effectively enhancing the stability and durability of engineered structures.

Product Feature
1.Stable and reliable mechanical properties: Thanks to its continuous filament structure, it boasts high tensilestrength and appropriate elongation, with consistent performance in dry and wet conditions, effectively withstanding stress from soil deformation and external loads.
2.Balanced permeability and filtration: Uniform pores between fibers enable efficient drainage while retaining soil particles to prevent loss, combining water seepage and filtration functions.
3.Strong environmental adaptability: Core materials (e.g., polyester filaments) feature excellent aging resistance, chemical inertness, and weatherability, maintaining long-term performance stability in complex soil, water, and climatic conditions.
4.Excellent structural integrity: The continuous filament structure, formed via processes like spunbonding and needle-punching, resists shedding or breakage, ensuring functional completeness during construction and use.

FAQ
What is the core material of Continuous Filament Geotextile? How does it different from Staple Fiber Geotextile ?
The core material of Continuous Filament Geotextile is polyester (PET) continuous filament, made from high-molecular-weight polymers. The fibres are formed through melt spinning and stretching into continuous long fibres, then processed into the final product via needle-punching or weaving techniques.
Key differences from staple fiber geotextile:
Fibre length: Filaments are continuous fibres (typically ≥100 mm in length), while short fibres are cut into short lengths (20–50 mm);
Performance: Long-strand geotextiles offer superior tensile strength, tear resistance, and abrasion resistance, making them suitable for high-strength engineering applications (e.g., highway subgrade reinforcement). Staple fiber geotextile are more cost-effective, have slightly better permeability, and are suitable for general waterproofing or filtration applications (e.g., agricultural water conservancy).
What do‘grammage’and‘strength’mean in relation to Continuous Filament Geotextiles? How should they be selected?
Grammage: Refers to the mass per unit area (unit: g/㎡), which is a fundamental parameter directly affecting strength and cost. Common specifications range from 100 to 600 g/㎡. Higher grammage indicates greater fibre usage and typically results in higher strength.
Strength: Core indicators include tensile strength (the force at break, unit: kN/m), tear strength (resistance to tearing, unit: kN), and CBR puncture strength (resistance to local puncture, unit: kN).
Selection criteria: Based on engineering design requirements (e.g., foundation bearing capacity, slope gradient, seepage rate), for example, highway subgrade reinforcement requires ≥30 kN/m tensile strength, corresponding to a basis weight of ≥300 g/m²; general filtration applications can select 200–300 g/m².
How durable is Continuous Filament Geotextile? How long is its service life?
Polyester filament yarn inherently possesses excellent weather resistance, but prolonged exposure to ultraviolet radiation, high temperatures, and acidic or alkaline environments can cause gradual degradation. The addition of antioxidants and UV stabilisers (such as carbon black) can significantly enhance its resistance to ageing.
Standard Continuous Filament Geotextiles (without special additives): outdoor service life of approximately 3–5 years;
Anti-ageing Continuous Filament Geotextiles: in buried or underwater environments, service life can exceed 50 years; in outdoor applications (such as slope protection), service life can be extended to 10–15 years.
When laying geotextile fabric, what should be done if wrinkles, damage, or unevenness in the base layer are encountered?
Crease handling: When laying, allow the material to relax naturally and avoid excessive stretching (allow for 1%-2% deformation). Minor creases can be flattened during subsequent backfilling, while severe creases require cutting and re-laying.
Damage repair: For small-area damage (diameter < 10 cm), patch with geotextile of the same specification (extending at least 10 cm beyond the damaged area); large-area damage requires cutting and replacement, with seams compacted or sewn.
Subgrade Preparation: Before installation, remove sharp debris (stones, rebar ends) from the subgrade. Flatness deviation must be ≤5 cm. Soft subgrades must be compacted or covered with a base layer (e.g., sand layer) beforehand.
