Filament Woven Geotextile
Product Introduction
GEOLEED filament woven geotextiles are made from high-modulus, high-strength polypropylene (PP) or polyester (PET) filament fibers through a precision weaving process. Its unique warp and weft arrangement structure gives it extremely high modulus and extremely low creep under tensile loads.
Woven geotextile: width 200-540 cm
Specification:200-2000g/㎡
Bringing in the advanced looms, Hock manufactures various PP woven with width from 2.1m to 4.6m, including reinforced woven, woven geobags, woven composite woven, sand pillows, soft mattress and other industrial fabrics.
Core Technical Specifications
Based on our previous export standards and third-party (SGS/TRI) testing reports, the core parameters are as follows:
Tensile Strength: Range from 20kN/m to 1200kN/m (custom ultra-high strength is available).
Elongation: Extremely low elongation, typically <15%, ensuring the long-term stability of the engineering structure.
CBR Bursting Strength: Up to 2.0kN - 15.0kN, effectively preventing mechanical damage during construction.
UV Resistance: Optimized for the high UV environment of the Middle East, with a strength retention rate of ≥70% after 500 hours.
Working Principle
1. High Modulus Reinforcement Principle
This is the core principle of woven fabric. Soil has high compressive strength but extremely low tensile strength.
Tensile Stress Transfer: When there is a vehicle load or the soil's own weight above, the soil tends to displace laterally outward.
Frictional Constraint: The woven fabric surface generates significant friction and interlocking forces with the soil particles. Through this interfacial shear stress, the tensile stress inside the soil is transferred to the high-strength woven fibers.
"Reinforcing Steel" Function: Like reinforcing steel in concrete, it increases the overall tensile strength of the soil, allowing us to build steeper slopes or construct roads on extremely soft foundations.
2. Separation Barrier Principle
In road engineering, the problem of "overlying gravel settling into lower soft soil" or "lower fine soil squeezing into upper gravel" is frequently encountered.
Preventing Mixing: The woven fabric forms a physical barrier. It ensures the crushed stone layer maintains its skeletal structure, thus preserving its designed load-bearing capacity.
Prevents the "pumping effect": Under dynamic loads, it prevents the underlying soft, fine soil from rising upwards due to moisture (i.e., "flooding"), preventing road structure failure.
3. Filtration and Reverse Filtration Principles: Although the woven fabric appears dense, it still possesses tiny, regularly spaced pores.
Permeable and Soil-Retaining: It allows water to pass freely axially in the vertical plane, releasing hydrostatic pressure within the soil.
Establishing a Natural Filter Layer: Over time, the woven fabric traps larger particles, which in turn trap smaller particles, eventually forming a self-filtering "natural filter layer" on the fabric's surface, thus preventing long-term soil erosion.
4. Drainage and Stress Distribution
Horizontal Stress Distribution: Due to the extremely high tensile strength and low elongation of the filaments, when subjected to vertical point loads, it can rapidly diffuse pressure along the horizontal plane to a wider area, thereby reducing the compressive stress per unit area of the foundation.
Edge Drainage: Even with woven fabrics, the gaps between the fibers can guide water to slowly drain away along the planar direction, mitigating water damage within the structure.

Application Case
Application
Applications of filament woven geotextile should primarily focus on heavy-duty, high-strength reinforcement, and harsh geographical environments.
1. Transportation Infrastructure Construction: This is the largest application area for filament woven geotextile.
Soft Soil Foundation Reinforcement: When constructing highways or railways in coastal areas, swamps, or areas with high water content, laying it as a base layer can effectively prevent subgrade settlement.
Temporary Construction Access Roads: For heavy equipment access in desert or muddy areas, laying high-strength woven geotextile ensures vehicles do not get stuck.
Airport Runways: Used in the runway base layer, it can absorb the enormous impact of takeoffs and landings, extending the life of the ground surface.
2. Marine & Hydraulic Engineering: Due to its high tensile strength and erosion resistance, filament woven geotextile is the first choice for hydraulic engineering.
Breakwaters and revetments: Lay beneath the breakwater stones to prevent waves from eroding the bottom sediment and causing structural collapse.
Land Reclamation: Used as a bottom-layer insulating material in reclamation projects to ensure effective separation of fill material from seabed silt.
Soft rafts: Large areas of woven fabric stitched together to form rafts, submerged to prevent riverbed erosion.
3. Reinforced Slopes & Retaining Walls: Utilizing their low elongation characteristics.
MSE Walls: Embedded in the soil as reinforcing material, allowing for the construction of near-90° vertical retaining walls, saving land space.
Landslide Control: Repairing collapsed slopes and enhancing the shear strength of the soil.
4. Environmental & Industrial Applications
Tailoring Dams and Landfills: Provide high-strength support at the bottom of landfills, protecting the upper geomembrane from punctures by sharp objects.
Geotextile Tubes: Utilizing the high strength and specific permeability of long-filament woven fabric, these are sewn into large tubes, into which sludge is injected for dewatering and consolidation.
